Question

我尝试在windows cmd上安装flask，在安装MarkupSafe模块时出现UnicodeDecodeError

Exception:
Traceback (most recent call last):
  File "c:\python36\lib\site-packages\pip\compat\__init__.py", line 73, in console_to_str
    return s.decode(sys.__stdout__.encoding)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 5: invalid continuation byte

During handling of the above exception, another exception occurred:

 File "c:\python36\lib\site-packages\pip\basecommand.py", line 215, in main
   status = self.run(options, args)

问题出在Pypi上的MarkupSafe缺少一个轮子。以下是解决方法（Windows上的git bash）：

git clone git@github.com:pallets/markupsafe.git /c/tmp/markupsafe
cd /c/tmp/markupsafe
./setup.py bdist_wheel
The result is a valid wheel: /c/tmp/markupsafe/dist/MarkupSafe-1.0-cp36-cp36m-win_amd64.whl.

在您需要使用它的其他项目中，只需调用

pip install /c/tmp/markupsafe/dist/MarkupSafe-1.0-cp36-cp36m-win_amd64.whl
