How To Fix - "error: Unable to find vcvarsall.bat"


In this post, we will see How To Fix - "error: Unable to find vcvarsall.bat". This is one of the errors commonly found while installing some packages in Python.


error: Unable to find vcvarsall.bat
  • When you try to install a package using say "pip install", if a wheel is available for your running version of Python, it gets downloaded and extracted. You do not need compilers as the extension modules included in wheels are already compiled.
  • When you see this error, this means you’re trying to install some package that has an extension module - however the compilation of that source code is not available.
  • “vcvarsall.bat” is part of the compiler that is required to compile the module.
  We will see how to fix this error.  

Solution 1 : 

  • Look for wheels of your respective package in the below link and try to use the wheel while installing the Python package.
https://www.lfd.uci.edu/~gohlke/pythonlibs/

  • Use the below command to install now -

python -m pip install <wheel\_file\_downloaded>
 

Solution 2:

  • Use a different Python distribution e.g. Anaconda - https://www.anaconda.com/products/individual#Downloads
 

Solution 3 :

  • Create a setup.py loading setuptools (Skip using distutils). setuptools will help patch-up and find vcvarsall.bat. Additional infocan be read from official cpython page - http://docs.cython.org/en/latest/src/reference/compilation.html

try:
  from setuptools import setup
  from setuptools import Extension
except ImportError:
  from distutils.core import setup
  from distutils.extension import Extension
 

Solution 4 :

  • Python modules has lots of components written in C or C++.
  • When you install such a Python package with pip (or setup.py), it is required to compile the C/C++ code. By default, pip assumes that you already have the MS Visual C++ compiler installed. But in case if you don't, then this error can occur.
  • So you can install - MS Visual C++ compiler or MinGW and then give it a try.
 

Solution 5 :

  • Try changing the compiler

python setup.py build --compiler=mingw32
  • Then install the package

python setup.py install
Do the steps below if not already done -

  • mingw32's should already be part of the environment PATH variable
e.g. append PATH with C:\programs\mingw\bin

  • Modify distutils.cfg - C:\Python27\Lib\distutils\distutils.cfg -

    \[build\]
    compiler=mingw32
  Hope this helps.
