python - 在虚拟环境中安装 gevent

Question

我刚开始使用 virtualenv，但我正在尝试安装 gevent在 virtualenv 环境中(我正在运行 Windows)。当我在 virtualenv 中使用 PIP 时，出现此错误:

MyEnv>pip install gevent
Downloading/unpacking gevent
  Running setup.py egg_info for package gevent
    Please provide path to libevent source with --libevent DIR

包索引有用于在 Windows 上安装的 MSI 和 EXE (http://pypi.python.org/pypi/gevent/0.13.7)，但我不知道如何将它们安装到 virtualenv 环境(或如果可能的话)。当我从 virtualenv promp 尝试 pip install gevent-0.13.7.win32-py2.7.exe 时，我也收到错误:

ValueError: ('Expected version spec in', 'D:\\Downloads\\gevent-0.13.7.win32-py2.7.exe', 'at', ':\\Downloads\\gevent-0.13.7.win32-py2.7.exe')

有人知道怎么做吗？

Pip 还不支持安装二进制包。如果你想从二进制包安装，你必须使用 easy_install - easy_install gevent-0.13.7.win32-py2.7.exe
