line_探查器安装失败：UnicodeDecodeE

Question

当试图通过pip install line_profiler安装line_profiler时，我总是得到相同的错误：

Installing collected packages: line-profiler
  Running setup.py install for line-profiler ... error
Exception:
Traceback (most recent call last):
  File "c:\program files\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 0xff in position 107: invalid start byte

During handling of the above exception, another exception occurred:

    status = self.run(options, args)

    return s.decode('utf_8')

注意：我手动地将cl.exe添加到路径变量中，因为我无法使vcvarsall.bat x64工作。在

有什么办法解决这个问题吗？我使用的是Python3.6:line\u profiler是否仅适用于Python2.X？在
