scikit-image 无法安装

Question

我正在尝试scikit-image使用 python 3.5 在我的 Windows 7 64 位机器上安装该软件包。安装scikit时，满足要求：

Requirement already satisfied: six>=1.7.3 in c:\users\x\appdata\local\programs\python\python35\lib\site-packages (from scikit-image)
Requirement already satisfied: networkx>=1.8 in c:\users\x\appdata\local\programs\python\python35\lib\site-packages (from scikit-image)
Requirement already satisfied: pillow>=2.1.0 in c:\users\x\appdata\local\programs\python\python35\lib\site-packages (from scikit-image)
Requirement already satisfied: PyWavelets>=0.4.0 in c:\users\x\appdata\local\programs\python\python35\lib\site-packages (from scikit-image)
Requirement already satisfied: decorator>=4.1.0 in c:\users\x\appdata\local\programs\python\python35\lib\site-packages (from networkx>=1.8->scikit-image)
Requirement already satisfied: numpy>=1.9.1 in c:\users\x\appdata\local\programs\python\python35\lib\site-packages (from PyWavelets>=0.4.0->scikit-image)

但最终，安装失败：

UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 114: character maps to <undefined>

  Failed building wheel for scikit-image
Command "C:\Users\X\AppData\Local\Programs\Python\Python35\python.exe -u -c "import setuptools, tokenize;__file__='C:\\Users\\X\\AppData\\Local\\Temp\\pycharm-packaging\\scikit-image\\setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record C:\Users\X\AppData\Local\Temp\pip-3hy8fcuv-record\install-record.txt --single-version-externally-managed --compile" failed with error code 1 in C:\Users\X\AppData\Local\Temp\pycharm-packaging\scikit-image\

我已经尝试过：

pip install -U wheel
pip install -U setuptools
pip install -U scipy

并且还升级 pip 本身，没有任何效果。

实际的解决方案是chcp 65001在安装命令之前键入。这将控制台的默认字符编码更改为 UTF-8，然后它就可以工作了。
