Python-使用pip安装时，我收到ValueError

我想用pip安装gevent，但当我尝试它时，最终会得到以下结果：

    ...
   File "c:\users\draffix\appdata\local\temp\pip_build_Draffix\gevent\setup.py", line 237, in build_extension

    result = build_ext.build_extension(self, ext)

  File "C:\Python33\lib\distutils\command\build_ext.py", line 517, in build_extension

    depends=ext.depends)

  File "C:\Python33\lib\distutils\msvc9compiler.py", line 460, in compile

    self.initialize()

  File "C:\Python33\lib\distutils\msvc9compiler.py", line 371, in initialize

    vc_env = query_vcvarsall(VERSION, plat_spec)

  File "C:\Python33\lib\distutils\msvc9compiler.py", line 287, in query_vcvarsall

    raise ValueError(str(list(result.keys())))

ValueError: ['path']

我使用的是Windows7，Python3.3，MicrosoftVisual2010。谢谢

我无法告诉您出现

值错误的具体原因

，但我相信您更关心的是安装gevent。但是，目前它不支持Python3。您可以关注更新。

谢谢，我不知道。无论如何，我把python降级到了2.7。现在一切都很顺利。
