当我在 virtualenv 中时无法 pip 安装包

Question

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，当我像这样使用 git bash 时：

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

我收到以下错误：

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: )
No matching distribution found for requests

但是，当我不在 virtualenv 中时，我可以 pip 安装包就好了。我已经阅读了很多关于类似错误的 SO 问题，但没有一个与我的情况非常匹配。

我尝试过的一些事情：卸载并重新安装 python；升级点子；切换 python 版本。

如果您能指出正确的方向，我将不胜感激

老问题，但我刚刚遇到了一个非常相似的问题，没有发布答案。

当我的 repo 在我的 G: 驱动器上，而 python 安装在 C: 上时。将 repo 移动到 C: 驱动器解决了我的问题，并且我能够使用 pip 安装我的 venv requirements.txt。

在 G:\

(env) G:\repo\>pip install -r requirements.txt
Collecting flask>=0.11 (from -r requirements.txt (line 1))
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connec

在 C:\
