我希望SO能够帮助解决这个问题。
当我在virtualenv中时，我无法pip安装任何软件包。我在Windows 7和python 2.7.12上。
例如，当我这样使用git bash时：

(venv2)
me@myhost ~/git/myrepo (master)
$ pip install requests

出现以下错误：

Collecting requests
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x02A438F0>: Failed to establish a new connection: [Errno 11003] getaddrinfo failed',)': /simple/requests/
Retrying (Retry(total=3, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x02A43790>: Failed to establish a new connection: [Errno 11003] getaddrinfo failed',)': /simple/requests/

Could not find a version that satisfies the requirement requests (from versions: )

然而，当我不在virtualenv中时，我可以很好地pip安装包。我读过很多关于类似错误的问题，但没有一个与我的情况非常匹配。
我试过一些事情：卸载并重新安装python;升级PIP;切换Python版本。
如果你能给我指明正确的方向，我将不胜感激

老问题，但我只是有一个非常相似的问题，并没有张贴答案。
当我的回购协议在我的G：驱动器，而Python安装在C：上。将存储库移动到C：驱动器解决了我的问题，我能够使用pip安装我的venv requirementsidertxt。
在G上：\

尝试运行上面的命令。2这可能会有帮助。3有时候安装软件包的问题可能与你的防火墙或网络提供商有关，所以我们将其保存为永久性的。
