I see steps are scattered in different answers. Based on my recent experience with this pytesseract error on Windows, writing different steps in sequence to make it easier to resolve the error:
1. Install tesseract using windows installer available at: <a href="https://github.com/UB-Mannheim/tesseract/wiki" rel="noreferrer">https://github.com/UB-Mannheim/tesseract/wiki</a>
2. Note the tesseract path from the installation. Default installation path at the time of this edit was: <code>C:\Users\USER\AppData\Local\Tesseract-OCR</code>. It may change so please check the installation path.
3. <code>pip install pytesseract</code>
4. Set the tesseract path in the script before calling <code>image_to_string</code>:
<code>pytesseract.pytesseract.tesseract_cmd = r'C:\Users\USER\AppData\Local\Tesseract-OCR\tesseract.exe'</code>

If you are getting an error like

<pre><code> tesseract is not installed or it's not in your path

 and 

 OSError: [Errno 12] Cannot allocate memory
</code></pre>

That might be and issue with the swap memory allocation issue

You can check this answer allocating more swap memory Hope that helps :)

I had the same issue on Windows. 
I tried to update the environment variables for the path of tesseract which did not work.

What worked for me was to modify the pytesseract.py which can be found at the path <code>C:\Program Files\Python37\Lib\site-packages\pytesseract</code> or usually in the <code>C:\Users\YOUR USER\APPDATA\Python</code>

I changed one line as per below:

<pre><code>#tesseract_cmd = 'tesseract' 
#tesseract_cmd = 'C:\Program Files\Tesseract-OCR\\tesseract.exe'
</code></pre>

Note I had to put an extra <code>\</code> before tesseract as Python was interpreting same as <code>\t</code> and you will get the below error message:

<blockquote>
 pytesseract.pytesseract.TesseractNotFoundError: C:\Program Files\Tesseract-OCR esseract.exe is not installed or it's not in your path
</blockquote>

blocks|key|1908466|text|也许这是因为，即使Tesseract被正确安装，您还没有安装您的语言，就像我的情况一样。幸运的是，这很容易修复，而且我甚至不需要处理tesseract_cmd。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1908467|sudo+apt-get+install+tesseract-ocr+-y

Perhaps this is happening because, even if Tesseract is correctly installed, you have not installed your language, as was my case. Fortunately this is very easy to fix, and I did not even need to mess with <code>tesseract_cmd</code>.
<pre><code>sudo apt-get install tesseract-ocr -y
sudo apt-get install tesseract-ocr-spa -y
tesseract --list-langs
</code></pre>
Note that in the second line we have specified <code>-spa</code> for Spanish.
If installation has been successful, you should get a list of your available languages, like:
<pre><code>List of available languages (3):
eng
osd
spa
</code></pre>
I found this at <a href="https://parzibyte.me/blog/2019/05/18/instalar-tesseract-ocr-idioma-espanol-ubuntu/" rel="nofollow noreferrer">this blog post</a> (Spanish). There is also a post for <a href="https://parzibyte.me/blog/2019/05/11/instalar-tesseract-ocr-windows-10/" rel="nofollow noreferrer">installation of Spanish language in Windows</a> (not as easy apparently).
Note: since the question uses <code>lang = 'eng'</code>, it is likely this is not the answer in that specific case. But the same error may happen in this other situation, which is why I posted the answer here.

There are already many nice answers to this problem but I would like to share a wonderful site that I came across when I couldnt solve the 'TesseractNotFound Error: tesseract is not installed or it's not in your path” Please refer this site: <a href="https://www.thetopsites.net/article/50655738.shtml" rel="nofollow noreferrer">https://www.thetopsites.net/article/50655738.shtml</a>
I realised that I got this error because I installed pytesseract with pip but forget to install the binary.
You are probably missing tesseract-ocr from your machine. Check the installation instructions here: <a href="https://github.com/tesseract-ocr/tesseract/wiki" rel="nofollow noreferrer">https://github.com/tesseract-ocr/tesseract/wiki</a>
On a Mac, you can just install using homebrew:
<code>brew install tesseract</code>
It should run fine after that!
Under Windows 10 OS environment, the following method works for me:
<ol>
<li>Go to <a href="https://github.com/tesseract-ocr/tesseract/wiki" rel="nofollow noreferrer">this link</a> and Download tesseract and install it. Windows version is available here: <a href="https://github.com/UB-Mannheim/tesseract/wiki" rel="nofollow noreferrer">https://github.com/UB-Mannheim/tesseract/wiki</a>
</li>
<li>Find script file pytesseract.py from C:\Users\User\Anaconda3\Lib\site-packages\pytesseract and open it. Change the following code from tesseract_cmd = 'tesseract' to: tesseract_cmd = 'C:/Program Files (x86)/Tesseract-OCR/tesseract.exe'
(This is the path where you install Tesseract-OCR so please check where you install it and accordingly update the path)
</li>
<li>You may also need to add environment variable C:/Program Files (x86)/Tesseract-OCR/
</li>
</ol>
Hope it works for you!

There looks to be an issue with the latest version of the pip module pytesseract=0.3.7.
I have downgraded it to pytesseract=0.3.6 and don't see the error.

For Windows in simple steps:
<ol>
<li>Download Windows version from <a href="https://github.com/UB-Mannheim/tesseract/wiki" rel="nofollow noreferrer">https://github.com/UB-Mannheim/tesseract/wiki</a>
</li>
<li>Install
</li>
<li>Write following in your .py file (check installed location)
<pre><code> pytesseract.pytesseract.tesseract_cmd = r&quot;C:\Program Files\Tesseract-OCR\tesseract.exe&quot;
 img_text = pytesseract.image_to_string(Image.open(filename))

for me it worked by putting single quote
<pre><code>pytesseract.pytesseract.tesseract_cmd =r'C:/Program Files/Tesseract-OCR/tesseract.exe'

actually putting inside double quotes was automatically inserting unwanted chracter

The above tips did not help me fix the problem, because the error specified in the section occurred when installing pytesseract (pycharm, python 2.7). The oddity was also that tesseract worked from the command line, so the installation was done correctly.
I was able to fix this problem by following these steps:
<ol>
<li>download pytesseract.py from the vault <a href="https://github.com/madmaze/pytesseract" rel="nofollow noreferrer">https://github.com/madmaze/pytesseract</a></li>
<li>remove all syntax errors related to the difference in the interpreters (2.7 and 3.*), including the try catch methods</li>
<li>import the edited script into your program as a self-written one and configure the tesseract_cmd variable according to the recommendations in the repository.</li>
</ol>
Subsequently, the image-to-text translation function worked in python 2.7

I am also facing an same error while installing tesseract in windows.
Based my recent problem solving i am following thsese below steps
<ol>
<li>Install tesseract using windows installer available in the gievn link: <a href="https://github.com/UB-Mannheim/tesseract/wiki" rel="nofollow noreferrer">https://github.com/UB-Mannheim/tesseract/wiki</a>
</li>
<li>Note the tesseract path from the installation. Default installation path at the time of this edit was: C:\Users\USER\AppData\Local\Tesseract-OCR. It may change so please check the installation path.
</li>
</ol>
After installations, still it is showing error or not installing error you are facing then press windows + R keys and run your file path (C:\Program Files\Tesseract-OCR\tesseract.exe) it wil work for me,
<pre><code>3. pip install pytesseract
</code></pre>
<a href="https://i.stack.imgur.com/AQu5d.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/AQu5d.png" alt="using command promt" /></a>
<ol start="4">
<li>Set the tesseract path in the script before calling ```image_to_string:``
</li>
<li>For windows file path -
</li>
</ol>
<pre><code>pytesseract.pytesseract.tesseract_cmd=r'C:\Program Files(x86)\Tesseract-OCR\tesseract.exe'
</code></pre>
<ol start="6">
<li>For installing opencv please - refer this <a href="https://stackoverflow.com/questions/70941904/opencv-facing-an-error-for-tesseract-moule-not-found-even-after-installations/70941905#70941905">question link</a>
</li>
<li>For linux installations
</li>
</ol>
<pre><code>$ sudo apt install tesseract-ocr
$ sudo apt install libtesseract-dev

</code></pre>
2.After running this command, you should something like this:
<pre><code>tesseract 4.0.0-beta.1 
 leptonica-1.75.3
</code></pre>
3.Once your tesseract installation is successful, you can run the following command to check
<pre><code>$ tesseract --list-langs
</code></pre>
4.You can expect the following output:
<pre><code>List of available languages (2):

5.linux file path was given below
<pre><code>pytesseract.pytesseract.tesseract_cmd = r'home/user/bin/tesseract'

this helped in my case

I'm trying to run a basic and very simple code in python. 

<pre><code>from PIL import Image
import pytesseract

im = Image.open("sample1.jpg")

text = pytesseract.image_to_string(im, lang = 'eng')

print(text)
</code></pre>

This is what it looks like, I have actually installed tesseract for windows through the installer. I'm very new to Python, and I'm unsure how to proceed? 

Any guidance here would be very helpful. I've tried restarting my Spyder application but to no avail.

Pytesseract : "TesseractNotFound Error: tesseract is not installed or it's not in your path", how do I fix this?
