I was having the same problem for the last two days and only have fixed it right now.

I had tried to use <code>--trust-host</code> option with the <code>DigiCert_High_Assurance_EV_Root_CA.pem</code> did not work, I couldn't install the ssl module (It tells it cannot be installed for python versions greater than 2.6), setting the <code>$PIP_CERT</code> variable didn't fix it either and I had <code>libssl1.0.2</code> and <code>libssl1.0.0</code> installed. Also worth mentioning I didn't had a <code>~/.pip/pip.conf</code> file, and creating it didn't solve the bug either.

What finally solved it, was installing python3.6 with <code>make</code> again.
Download the Python-3.6.0.tgz from the website, run <code>configure</code> then <code>make</code>, <code>make test</code> and <code>make install</code>. Hope it works for you.

The problem probably caused by library missing.

Before you install python 3.6, make sure you install all the libraries required for python.

If you are on OSX and have compiled python from source:

Install openssl using brew <code>brew install openssl</code>

Make sure to follow the instructions brew gives you about setting your <code>CPPFLAGS</code> and <code>LDFLAGS</code>. In my case I am using the <code>openssl@1.1</code> brew formula and I need these 3 settings for the python build process to correctly link to my SSL library:

<pre><code>export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"
export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"
</code></pre>

Assuming the library is installed at that location.

Agree with the answer by mastaBlasta. Worked for me. I encountered the same problem as the topic description. 

Environment: MacOS Sierra. And I use Homebrew.

My solution:

<ol>
<li>Reinstall openssl by <code>brew uninstall openssl; brew install openssl</code></li>
<li>According to the hints given by Homebrew, do the following:

<pre><code>echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' &gt;&gt; ~/.bash_profile
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

The <a href="https://devguide.python.org/setup/" rel="nofollow noreferrer" title="python documentation">python documentation</a> is actually very clear, and following the instructions did the job whereas other answers I found here were not fixing this issue. 

<ol>
<li>first, install python 3.x.x from source using, for example with version 3.6.2 <a href="https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz" rel="nofollow noreferrer">https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz</a></li>
<li>make sure you have openssl installed by running <code>brew install openssl</code></li>
<li>unzip it and move to the python directory: <code>tar xvzf Python-3.6.2.tar.xz &amp;&amp; cd Python-3.6.2</code></li>
<li>then if the python version is &lt; 3.7, run </li>
</ol>

<code>CPPFLAGS="-I$(brew --prefix openssl)/include" \
 LDFLAGS="-L$(brew --prefix openssl)/lib" \
 ./configure --with-pydebug
</code>
5. finallly, run <code>make -s -j2</code> (<code>-s</code> is the silent flag, <code>-j2</code> tells your machine to use 2 jobs)

I encountered the same problem on windows 10. My very specific issue is due to my installation of Anaconda. I installed Anaconda and under the path <code>Path/to/Anaconda3/</code>, there comes the <code>python.exe</code>. Thus, I didn't install python at all because Anaconda includes python. When using pip to install packages, I found the same error report, <code>pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.</code>. 

The solution was the following:

1) you can download python again on the official <a href="https://www.python.org/downloads/release/python-372/" rel="noreferrer">website</a>;

2) Navigate to the directory where <code>"Python 3.7 (64-bit).lnk"</code>is located

3) <code>import ssl</code> and <code>exit()</code>

If you are on Windows and use anaconda this worked for me:

I tried a lot of other solutions which did not work (Environment PATH Variable changes ...)

The problem can be caused by DLLs in the Windows\System32 folder (e.g. libcrypto-1_1-x64.dll or libssl-1_1-x64.dll or others) placed there by other software.

The fix was installing openSSL from <a href="https://slproweb.com/products/Win32OpenSSL.html" rel="noreferrer">https://slproweb.com/products/Win32OpenSSL.html</a> which replaces the dlls by more recent versions.

The <code>ssl</code> module is a TLS/SSL wrapper for accessing Operation Sytem (OS) socket (<a href="https://docs.python.org/3/library/ssl.html" rel="nofollow noreferrer">Lib/ssl.py</a>). So when <code>ssl</code> module is not available, chances are that you either don't have OS OpenSSL libraries installed, or those libraries were not found when you install Python. Let assume it is a later case (aka: you already have OpenSSL installed, but they are not correctly linked when installing Python).

I will also assume you are installing from source. If you are installing from binary (ie: Window .exe file), or package (Mac .dmg, or Ubuntu apt), there is not much you can do with the installing process.

During the step of configuring your python installation, you need to specify where the OS OpenSSL will be used for linking:

<pre><code># python 3.8 beta
./configure --with-openssl="your_OpenSSL root"
</code></pre>

So where will you find your installed OpenSSL directory?

<pre><code># ubuntu 
locate ssl.h | grep '/openssl/ssl.h'

/home/user/.linuxbrew/Cellar/openssl/1.0.2r/include/openssl/ssl.h
/home/user/envs/py37/include/openssl/ssl.h
/home/user/miniconda3/envs/py38b3/include/openssl/ssl.h
/home/user/miniconda3/include/openssl/ssl.h
/home/user/miniconda3/pkgs/openssl-1.0.2s-h7b6447c_0/include/openssl/ssl.h
/home/user/miniconda3/pkgs/openssl-1.1.1b-h7b6447c_1/include/openssl/ssl.h
/home/user/miniconda3/pkgs/openssl-1.1.1c-h7b6447c_1/include/openssl/ssl.h
/usr/include/openssl/ssl.h
</code></pre>

Your system may be different than mine, but as you see here I have many different installed openssl libraries. As the time of this writing, python 3.8 expects openssl 1.0.2 or 1.1:

<blockquote>
 Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().
</blockquote>

So you would need to verify which of those installed libraries that you can use for linking, for example

<pre><code>/usr/bin/openssl version

OpenSSL 1.0.2g 1 Mar 2016
</code></pre>

<pre><code>./configure --with-openssl="/usr"
make &amp;&amp; make install
</code></pre>

You may need to try a few, or install a new, to find the library that would work for your Python and your OS.

I finally solve this issue. These are the detail of my env: 
Version of Python to install: 3.6.8 
OS: Ubuntu 16.04.6 LTS 
Root access: No 
 
Some people suggest to install <code>libssl-dev</code>, but it did not work for me. I follow <a href="https://help.dreamhost.com/hc/en-us/articles/115000702772-Installing-a-custom-version-of-Python-3" rel="nofollow noreferrer">this link</a> and I fixed it! 
In short, I download, extract, build, and install OpenSSL (openssl-1.1.1b.tar.gz). Then, I modify <code>.bashrc</code> file <a href="https://help.dreamhost.com/hc/en-us/articles/360001435926-Installing-OpenSSL-locally-under-your-username" rel="nofollow noreferrer">follow this link</a>. 
Next, I download and extract Python-3.6.8.tgz. I edit Modules/Setup.dist to modify SSL path (lines around #211). I did <code>./configure --prefix=$HOME/opt/python-3.6.8</code>, <code>make</code> and <code>make install</code>. Last, I modify my <code>.bashrc</code>. Notice that I do not include <code>--enable-optimizations</code> in <code>./configure</code>.

(NOT on Windows!)
This made me tear my hair out for a week, so I hope this will help someone
I tried everything short of re-installing Anaconda and/or Jupyter.
Setup
<ul>
<li>AWS Linux</li>
<li>Manually installed Anaconda 3-5.3.0</li>
<li>Python3 (3.7) was running inside anaconda (ie, <code>./anaconda3/bin/python</code>)</li>
<li>there was also <code>/usr/bin/python</code> and <code>/usr/bin/python3</code> (but these were not being used as most of the work was done in Jupyter's terminal)</li>
</ul>
Fix
In Jupyter's terminal:
<code>cp /usr/lib64/libssl.so.10 ./anaconda3/lib/libssl.so.1.0.0</code>
<code>cp /usr/lib64/libcrypto.so.10 ./anaconda3/lib/libcrypto.so.1.0.0</code>
What triggered this?
So, this was all working until I tried to do a <code>conda install conda-forge</code>
I'm not sure what happened, but conda must have updated <code>openssl</code> on the box (I'm guessing) so after this, everything broke.
Basically, unknown to me, conda had updated openssl, but somehow deleted the old libraries and replaced it with <code>libssl.so.1.1</code> and <code>libcrypto.so.1.1</code>.
Python3, I guess, was compiled to look for <code>libssl.so.1.0.0</code>
In the end, the key to diagnosis was this:
<code>python -c &quot;import ssl; print (ssl.OPENSSL_VERSION)&quot;</code>
gave the clue <code>library &quot;libssl.so.1.0.0&quot; not found</code>
The huge assumption I made is that the <code>yum</code> version of ssl is the same as the <code>conda</code> version, so just renaming the shared object might work, and it did.
My other solution was to re-compile python, re-install anaconda, etc, but in the end I'm glad I didn't need to.
Hope this helps you guys out.

I had the same issue with python3.8.5 installation on Debian9. I have done a build, but when I have tried to download some modules, pip3.8 issued following error:
<pre><code>pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
</code></pre>
I have searched for the root of my problem and found out that there is a system dependent portion of the python build which is called by system independent one. In case of missing ssl you just needed to open python terminal and check whether is _ssl present:
<pre><code>&gt;&gt;&gt; help('modules')
.
.
_sre enum pwd wave
_ssl errno py_compile weakref
_stat faulthandler pyclbr webbrowser
.
.
</code></pre>
If not your system dependent ssl module part is missing. You can check it also by listing content of &lt;python_installation_root&gt;/lib/python3.8/lib-dynload:
<pre><code>&gt;ls ./lib/python3.8/lib-dynload | grep ssl
_ssl.cpython-38-x86_64-linux-gnu.so
</code></pre>
The problem was caused as written by PengShaw by missing libssl-dev during the build. Therefore you have to follow the recommended python installation flow. First install prerequisites and then build and install the python. Installation without devel versions of libs resulted in my case in the missing system dependent part. In this case _ssl.
Note that the devel lib name differs for Debian and CentOS, therefore check whether the installation hints posted on net are suitable for your specific Linux system type:
<pre><code>For Debian:
sudo apt install -y libbz2-dev libffi-dev libssl-dev
./configure --enable-optimizations
make
make altinstall


For CentOS:
sudo yum -y install bzip2-devel libffi-devel openssl-devel
./configure --enable-optimizations
make
make altinstall
</code></pre>
It is for sure a good idea to list configuration options prior the configuration and evtl. use some additional options:
<pre><code>./configure --help
</code></pre>
Last but not least in case you use --prefix for a non-default installation location, remember to add your &lt;python_installation_root&gt;/lib to your LD_LIBRARY_PATH .
