Even though Python is an interpreted language, you may need to install Windows C++ compilers in some cases. Unlike Linux, compilers for Windows are not included by default in the OS.

For example, you will need to use them if you wish to:

Microsoft provides official C++ compilers called Visual C++, you can find them bundled with Visual Studio or, for some versions, in standalone distributions. Some alternative compilers exist like MinGW, but incompatibilities may occur with a CPython official distribution that is built with Microsoft Visual C++.

The compiler's architecture must be the same as Python's (for example: if you use Python 64bit, you have to use an x64 compiler).

Which Microsoft Visual C++ compiler to use with a specific Python version ?

Each Python version uses a specific compiler version (e.g. CPython 2.7 uses Visual C++ 9.0, CPython 3.3 uses Visual C++ 10.0, .). So, you need to install the compiler version that corresponds to your Python version :

Visual C++

CPython

14.0

3.5

10.0

3.3, 3.4

9.0

2.6, 2.7, 3.0, 3.1, 3.2

Compilers Installation and configuration

Compatible architectures are specified for each compiler in brackets.

Microsoft Visual C++ 14.0 standalone: Visual C++ Build Tools 2015 (x86, x64, ARM)

This is a standalone version of Visual C++ 14.0 compiler, you don't need to install Visual Studio 2015.

You have to run your commands from Visual C++ Build Tools Command Prompt (C:\Program Files (x86)\Microsoft Visual C++ Build Tools\) each time you want compile with Python.

(!) If you want automatic use of this compiler with Python, you can also edit the C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat and replace its contents with the following text :

   1 rem Vcvarsall for Visual C++ Build Tools 2015
   2 @echo off
   3 set vcprogramfiles=%ProgramFiles(x86)%
   4 if "%vcprogramfiles%"=="" set vcprogramfiles=%ProgramFiles%
   5 call "%vcprogramfiles%\Microsoft Visual C++ Build Tools\vcbuildtools.bat" %*

Microsoft Visual C++ 14.0 with Visual Studio 2015 (x86, x64, ARM)

Visual Studio 2015 contains Visual C++ 14.0 compiler. Distutils will automatically detect the compiler and use it.

Microsoft Visual C++ 10.0 standalone: Windows SDK 7.1 (x86, x64, ia64)

This is a standalone version of Visual C++ 10.0 compiler, you don't need to install Visual Studio 2010.

You have to run your commands from Windows SDK 7.1 Command Prompt (C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd) each time you want to compile with Python. By default, SetEnv.cmd uses the x86 architecture, use /x64 or /ia64 arguments to change it.

(!) If you want automatic use of this compiler with Python, you can also edit the C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat file and replace its contents with the following text :

   1 rem Vcvarsall for Windows SDK 7.1
   2 @echo off
   3 if /i "%1" == "x64" (
   4     set vcvararch=x64
   5 ) else if /i "%1" == "amd64" (
   6     set vcvararch=x64
   7 ) else if /i "%1" == "x86_amd64" (
   8     set vcvararch=x64
   9 ) else if /i "%1" == "ia64" (
  10     set vcvararch=ia64
  11 ) else if /i "%1" == "x86_ia64" (
  12     set vcvararch=ia64
  13 ) else (
  14     set vcvararch=x86
  15 )
  16 set vcprogramfiles=%ProgramFiles(x86)%
  17 if "%vcprogramfiles%"=="" set vcprogramfiles=%ProgramFiles%
  18 call "%vcprogramfiles%\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd" /%vcvararch%

Microsoft Visual C++ 10.0 with Visual Studio 2010 (x86, x64, ia64)

Visual Studio 2010 contains Visual C++ 10.0 compiler. Distutils will automatically detect the compiler and use it. The Express edition of Visual Studio 2010 only bundles a compiler for x86.

Microsoft Visual C++ 9.0 standalone: Visual C++ Compiler for Python 2.7 (x86, x64)

This is a standalone version of Visual C++ 9.0 compiler, you don't need to install Visual Studio 2008.

pip install --upgrade setuptools

{i} Even though this package's name refers to Python 2.7 specifically, you can use it with all Python versions that use Visual C++ 9.0.

Microsoft Visual C++ 9.0 standalone: Windows SDK 7.0 (x86, x64, ia64)

This is a standalone version of Visual C++ 9.0 compiler, you don't need to install Visual Studio 2008.

/!\ The use of Microsoft Visual C++ Compiler for Python 2.7 is recommended (If you don't need to compile for ia64). See the previous paragraph to install it.

You have to run your commands from Windows SDK 7.0 Command Prompt (C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0\Bin\SetEnv.cmd) each time you want to compile with Python. By default, SetEnv.cmd uses the x86 architecture, use /x64 or /ia64 arguments to change it.

Microsoft Visual C++ 9.0 standalone: Windows SDK 6.1 (x86, x64, ia64)

This is a standalone version of Visual C++ 9.0 compiler, you don't need to install Visual Studio 2008.

/!\ Windows SDK 6.1 was upgraded by Microsoft to Windows SDK 7.0. See the previous paragraph to install it.

You have to run your commands from Windows SDK 6.1 Command Prompt (C:\Program Files (x86)\Microsoft SDKs\Windows\v6.1\Bin\SetEnv.cmd) each time you want to compile with Python. By default, SetEnv.cmd uses the x86 architecture, use /x64 or /ia64 arguments to change it.

Microsoft Visual C++ 9.0 with Visual Studio 2008 (x86, x64, ia64)

Visual Studio 2008 contains Visual C++ 9.0 compiler. Distutils will automatically detect the compiler and use it. The Express edition of Visual Studio 2008 only bundles a compiler for x86.

MinGW (x86)

MinGW is an alternative C++ compiler that works with all Python versions.

  • Install Minimalist GNU For Windows into C:\MinGW.

  • Open MinGW Installation Manager, check mingw32-base and mingw32-gcc-g++, and Apply Changes in the Installation menu.

  • Add C:\MinGW\bin to the PATH environment variable (With ";" before if PATH is not empty).

  • Create a distutils.cfg file with the following contents in the folder \Lib\distutils in Python install directory :

   1 [build]
   2 compiler=mingw32
   3 
   4 [build_ext]
   5 compiler=mingw32
