Question

我在运行pip install requests[security]==2.10.0时出现问题。

我是使用virtualenv bento/debian-7.8在Python 2.7.3上运行此内容。

这是错误：

Collecting cryptography>=1.9 (from pyOpenSSL>=0.13->requests[security]==2.10.0->-r requirements.txt (line 22))
Exception:

NameError: name 'python_implementation' is not defined

这个问题很可能是因为你的virtualenv中有一个过时的pip版本。尝试使用以下命令升级它：

pip install --upgrade pip

pip install requests [security] NameError：name＆＃39; python_implementation＆＃39;没有定义
