TLDR run vcvars64 bat After endlessly searching through similar questions with none of the solutions working  -Adding endless folders to my path and removing them  uninstalling and reinstalling visual studio commmunity and build tools  and step by step attempting to debug I finally found a solution that worked for me   background notes if anyone is in a similar situation  I recently reset my main computer and after reinstalling the newest version of python  Python3 9  libraries I used to install with no troubles  main example pip install opencv-python  gave cl     is not a full path and was not found in the PATH   after adding cl to the path from C  Program Files  x86  Microsoft Visual Studio 2019 Community VC Tools MSVC 14 27 29110 bin Hostx64 x64 and several different windows kits one at a time getting the following  The C compiler   quot C  Program Files  x86  Microsoft Visual Studio 2019 Community VC Tools MSVC 14 27 29110 bin Hostx64 x64 cl exe quot   is not able to compile a simple test program   with various link errors or  quot  Run Build Command s  jom  nologo cmTC 7c75e fast  amp  amp  The system cannot find the file specified quot  upgrading setuptools and wheel from both a regular command line and an admin one did nothing as well as trying to manually download a wheel or trying to install with --only-binary  all  Finally the end result that worked for me was running the correct vcvars bat for my python installation namely running  quot C  Program Files  x86  Microsoft Visual Studio 2019 Community VC Auxiliary Build vcvars64 bat quot  once  not vcvarsall or vcvars32   because my python installed was 64 bit  and then running the regular command pip install opencv-python worked

As the other responses pointed out  one solution is to install Visual Studio 2015  However  it takes a few GBs of disk space  One way around is to install precompiled binaries  The webpage http   www lfd uci edu  gohlke pythonlibs   mirror   contains precompiled binaries for many Python packages  After downloading the package of interest to you  you can install it using pip install  e g  pip install mysqlclient-1 3 10-cp35-cp35m-win amd64 whl

Use the link to Visual C   2015 Build Tools  That will install Visual C   14 0 without installing Visual Studio

User · Answer

Your path only lists Visual Studio 11 and 12  it wants 14  which is Visual Studio 2015  If you install that  and remember to tick the box for Languages- gt C   then it should work    On my Python 3 5 install  the error message was a little more useful  and included the URL to get it from   error  Microsoft Visual C   14 0 is required  Get it with  Microsoft Visual C   Build Tools   http   landinghub visualstudio com visual-cpp-build-tools   Edit  New working link  Edit  As suggested by Lightfire228  you may also need to upgrade setuptools package for the error to disappear   pip install --upgrade setuptools

This works for me  pip install --only-binary  all  mysqlclient

User · Answer

Binary install it the simple way   I can t believe no one has suggested this already - use the binary-only option for pip  For example  for mysqlclient   pip install --only-binary  all  mysqlclient   Many packages don t create a build for every single release which forces your pip to build from source  If you re happy to use the latest pre-compiled binary version  use --only-binary  all  to allow pip to use an older binary version

I had the same exact issue on my windows 10 python version 3 8  In my case  I needed to install mysqlclient were the error occurred Microsoft Visual C   14 0 is required  Because installing visual studio and it s packages could be a tedious process  Here s what I did   step 1 - Go to unofficial python binaries from any browser and open its website    step 2 - press ctrl F and type whatever you want  In my case it was mysqlclient   step 3 - Go into it and choose according to your python version and windows system  In my case it was mysqlclient-1 4 6-cp38-cp38-win32 whl and download it      step 4 - open command prompt and specify the path where you downloaded your file  In my case it was C  Users user Downloads  step 5 - type pip install   mysqlclient-1 4 6-cp38-cp38-win32 whl and press enter   Thus it was installed successfully  after which I went my project terminal re-entered the required command  This solved my problem  Note that  while working on the project in pycharm  I also tried installing mysql-client from the project interpreter  But mysql-client and mysqlclient are different things  I have no idea why and it did not work

To expand on the answers by ocean800  davidsheldon and user3661384    You should now no longer use Visual Studio Tools 2015 since a newer version is available   As indicated by the Python documentation you should be using Visual Studio Tools 2017 instead      Visual C   Build Tools 2015 was upgraded by Microsoft to Build Tools for Visual Studio 2017    Download it from here  You will require also need setuptools   if you don t have setup tools run   pip install setuptools   Or if you already have it  be sure to upgrade it   pip install setuptools --upgrade   For the Python documentation link above you will see that setuptools version must be at least 34 4 0  for VS Tools to work

If you have already installed Visual Studio Build Tools  as in other comments   and upgraded setuptools but it still doesn t work  Make sure to run pip under x86 or x64 Native Tools Command Prompt  It can be found under VS folder in Windows start menu  The default command line prompt may NOT provide Pip the path to the VS build tool  as is in my case

I had the same issue while installing mysqlclient for the Django project   In my case  it s the system architecture mismatch causing the issue  I have Windows 7 64bit version on my system  But  I had installed Python 3 7 2 32 bit version by mistake    So  I re-installed Python interpreter  64bit  and ran the command  pip install mysqlclient   I hope this would work with other Python packages as well

If Visual Studio is NOT your thing  and instead you are using VS Code  then this link will guide you thru the installer to get C   running on your Windows   You only needs to complete the Pre-Requisites part  https   code visualstudio com docs cpp config-msvc   prerequisites  This is similar with other answers  but this link will probably age better than some of the responses here   PS  don t forget to run pip install --upgrade setuptools
