I solved this problem using this command:

I have Python 3.7 in my machine.

Cool way to solve this issue for all your python version and without checking your version on macOS

<pre class="lang-sh prettyprint-override"><code>bash /Applications/Python*/Install\ Certificates.command
</code></pre>

This command is equivalent to:

<pre><code>...
bash /Applications/Python\ 2.7/Install\ Certificates.command
bash /Applications/Python\ 3.6/Install\ Certificates.command
bash /Applications/Python\ 3.7/Install\ Certificates.command
...
</code></pre>

A cheap way around this is just using python3.5 if you still have it installed.

Pushing to PyPI:

<code>python3.5 setup.py register -r pypitest</code>

<code>python3.5 setup.py sdist upload -r pypitest</code>

pipping seems to work fine with 3.6 out of the box..

I faced the same problem, when I tried to run Python with Keras data loading. The error for me was:

<pre><code>Exception: URL fetch failure on AWS_URL: None -- [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:833)

I fixed my problem by upgrading the certificate as:

<pre><code>pip install --upgrade certifi

For me, it was a misspecification of the request. I'd made a <code>https</code> call instead of a <code>http</code> call. Changing to http solved it.

Ensure that you do not have <code>SSL_CERT_FILE</code> environment variable set. I had the same problem, it took a while before I figured out some application was setting this variable as an empty string inside my bash profile.

If you're using MacOS go to Applications &gt;&gt; python3.8 &gt;&gt; and double-click Install Certificates.command.
This worked for me.

Just REINSTALL your Python on your Mac

sometimes if you're using conda or poetry you may be in a virtual environment shell. you can check with:
<code>which python</code>
for me the solution was as simple as <code>cmd+t</code> to open a new shell.

Many operations in python require accessing things via https. This includes pip install, or just using http.client.HTTPSConnection, or any modules or applications that use these things internally.

If python was installed from the official python pkg installer, downloaded from <a href="https://python.org" rel="noreferrer">https://python.org</a>, then it uses an internal version of openssl, and contains no root certificates. Anything that uses an SSL connection results in this error:

<pre><code>ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)
</code></pre>

How can I install root certs to make the above error go away?

python中的许多操作都需要通过https访问。这包括pip安装，或者只使用http.client.HTTPSConnection，或者在内部使用这些东西的任何模块或应用程序。如果python是从官方的python pkg安装程序安装的，从下载的，那么它使用的是openssl的内部版本，并且不包含根证书。任何使用SSL连接的操作都会导致以下错误：ssl.SSLError: [SSL: CERTI
