使用pip安装python插件的时候出现Microsoft Visual C++ 9.0缺失错误

：

  Running setup.py install for gevent

    building 'gevent.corecext' extension

    error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from http://aka.ms/vcpython27

    Complete output from command C:\Python27\python.exe -c "import setuptools, tokenize;__file__='c:\\users\\hello\\appdata\\local\\temp\\pip_build_hello\\gevent\\setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record c:\users\hello\appdata\local\temp\pip-okbpxc-record\install-record.txt --single-version-externally-managed --compile:

Cleaning up...【以下为红色】

Command C:\Python27\python.exe -c "import setuptools, tokenize;__file__='c:\\users\\hello\\appdata\\local\\temp\\pip_build_hello\\gevent\\setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record c:\users\hello\appdata\local\temp\pip-okbpxc-record\install-record.txt --single-version-externally-managed --compile failed with error code 1 in c:\users\hello\appdata\local\temp\pip_build_hello\gevent

Storing debug log for failure in C:\Users\hello\pip\pip.log

 

尝试解决方案

到http://aka.ms/vcpython27下载vc4python27 安装后重试

结果：解决了部分问题，然后又提示zlib缺少，可以看pip.log
