I'm trying install psycopg2 into my virtualenv. I've tried pip I've tried easy_install nothing is working... installing from pip is the more desirable choice but it has to be done through nwcell's github package https://github.com/nwcell/psycopg2-windowsheres the command I've been using:
我正在尝试将 psycopg2 安装到我的 virtualenv 中。我试过 pip 我试过 easy_install 没有任何效果...从 pip 安装是更理想的选择，但它必须通过 nwcell 的 github 包 https://github.com/nwcell/psycopg2-windows这里的命令来完成我一直在使用：

As the docssay:
正如文档所说：
pip supports installing from Git, Mercurial, Subversion and Bazaar, and detects the type of VCS using url prefixes: "git+", "hg+", "bzr+", "svn+".
pip requires a working VCS command on your path: git, hg, svn, or bzr.
pip 支持从 Git、Mercurial、Subversion 和 Bazaar 安装，并使用 url 前缀检测 VCS 的类型：“git+”、“hg+”、“bzr+”、“svn+”。
pip 需要在您的路径上使用有效的 VCS 命令：git、hg、svn 或 bzr。
So, if you don't have a working gitcommand on your %PATH%, you can't pip install git+<anything>. To fix it, install git, and make sure it ends up on your %PATH%.
所以，如果你没有工作做git在你的命令%PATH%，你不能pip install git+<anything>。要修复它，请安装git，并确保它最终出现在您的%PATH%.
