如何在Windows 7上编译和安装python 2.7的pysqlcipher

Question

I have recently installed Python 2.7 on Windows 7. I have also installed setuptools and pip for python, MinGW, Visual C++ for Python , and OpenSSL over the course of my trials. All have entries in my %PATH% and I have the environment variables VS90COMNTOOLS and VS100COMNTOOLS pointing to "C:\\Users\\username\\AppData\\Local\\Programs\\Common\\Microsoft\\Visual C++ for Python\\9.0\\VC\\bin".

I have tried several different ways to install this. I will outline each below. (all of there were run from an elevated command prompt.)

1. Download source and compile.

   python setup.py install

This gives the output:

running install
running build
running build_py
running build_ext
building 'pysqlcipher._sqlite' extension
error: Unable to find vcvarsall.bat

2. Compile source using MinGW

Since after installing VS for Python I still got the same error, I decided to try:

setup.py install build --compiler=mingw32

Output:

running install
running build
running build_py
running build_ext
building 'pysqlcipher._sqlite' extension

3. I installed OpenSSL and tried again. Still the same output. I also installed pyopenssl. Still the same error.

4. I tried going the easy way:

   easy_install pysqlcipher

   pip install pysqlcipher

These also complain about not being able to find 'openssl/rand.h'

Does anyone have any ideas how to resolve this so I can compile this package for Windows? Thanks!

Answer 1

This is most common issue, I have faced. But I used pytools for Visual Studio 2012 to solve this. After installing pytools a new project category is added in New Project

Select your python project. Add python environment from your project Solution Explorer, right click on it and select "Add / Remove Python Environment...". A window will appear with check box option, select your current python version (installed in your system).

An environment will be added like (Here Python 2.7). Again right click on it and select "Install Python Package" option.

A window is rise with pip and easy_install option. Now just type your package name eg. pyopenssl. Check run as administrator. Click ok button

Console output determines is your package installed perfectly or not.

I hope this'll help you.

Method 1

Install the Microsoft Visual C++ Compiler for Python 2.7

Update pip

python -m pip install -U pip

Update setuptools

pip install -U setuptools

Use pip to install pysqlcipher

pip install pysqlcipher

pip should be able to find your install of the Visual C++ Compiler, and compile the needed extensions.

If for some reason you can't use pip, then try method 2 below.

Method 2

Look in your setup.py If it is an older package it may be importing distutils.core.setup() rather than setuptools.setup() .

I ran in to this (in 2015) with a combination of these factors:

1. The Microsoft Visual C++ Compiler for Python 2.7 from http://aka.ms/vcpython27

2. An older package that uses distutils.core.setup()

3. Trying to do python setup.py build rather than using pip .

If you use a recent version of pip, it will force (monkeypatch) the package to use setuptools, even if its setup.py calls for distutils. However, if you are not using pip, and instead are just doing python setup.py build , the build process will use distutils.core.setup() , which does not know about the compiler install location.

Step 1: Install the Microsoft Visual C++ Compiler for Python 2.7

Step 2: Open the appropriate Visual C++ 2008 Command Prompt

Open the Start menu or Start screen, and search for "Visual C++ 2008 32-bit Command Prompt" (if your python is 32-bit) or "Visual C++ 2008 64-bit Command Prompt" (if your python is 64-bit). Run it. The command prompt should say Visual C++ 2008 ... in the title bar.

Step 3: Set environment variables

Set these environment variables in the command prompt you just opened.

SET DISTUTILS_USE_SDK=1
SET MSSdk=1

Reference http://bugs.python.org/issue23246

Step 4: Build and install

cd to the package you want to build, and run python setup.py build , then python setup.py install . If you want to install in to a virtualenv, activate it before you build.
