系统win10 64位，python版本3.7.4。
在网上下载了scikit-learn-0.22.tar，解压后利用python setup.py install进行安装时报错。
代码如下：
PS C:\Users\TH.Liu> cd E:\python\Scripts\scikit-learn-0.22\scikit-learn-0.22
PS E:\python\Scripts\scikit-learn-0.22\scikit-learn-0.22> python setup.py install

实际上，这俩错误我都在网上找过许多解决方式，但都没有用。下载了VS2010并尝试过在cmd中设置VS90COMNTOOLS =％VS100COMNTOOLS％，依然无效。
抱着最后的希望来这里求助……希望能得到解决。

2019.12.17 更新：
在安装了VS2015之后，vcvarsall.bat的问题消失了，剩下的只有：
E:\python\lib\distutils\dist.py:274: UserWarning: Unknown distribution option: 'project_urls'
warnings.warn(msg)
E:\python\lib\distutils\dist.py:274: UserWarning: Unknown distribution option: 'python_requires'

warnings.warn(msg)
No module named 'numpy.distutils._msvccompiler' in numpy.distutils; trying from distutils
这些问题了。
大家说PowerShell容易出BUG，我换用CMD后依旧如此。
我依旧没有找到这些报错的解决方案，希望得到大佬的帮助！
