Windows 上的 Python 2.7.9 安装请求

Question

我一直在尝试安装请求，但每次我这样做都会启动，然后给我这个错误。有什么办法可以解决这个问题或修复这个错误，以便我可以使用请求？

Storing debug log for failure in C:\Users\l--l\pip\pip.log

我已正确进入文件，但似乎无法让它下载请求。

重新安装 pip

curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
python2.7 get-pip.py

安装请求

python2.7 -m pip install requests

或手动安装

git clone git://github.com/psf/requests.git
cd requests
python2.7 -m pip install .
