尝试通过安装 line_profiler时 pip install line_profiler，我不断收到相同的错误：

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:

Traceback (most recent call last):
  File "c:\program files\python36\lib\site-packages\pip\basecommand.py", line 215, in main
    status = self.run(options, args)

    prefix=options.prefix_path,
  File "c:\program files\python36\lib\site-packages\pip\req\req_set.py", line 784, in install
    **kwargs

    line = console_to_str(proc.stdout.readline())
  File "c:\program files\python36\lib\site-packages\pip\compat\__init__.py", line 75, in console_to_str
    return s.decode('utf_8')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 107: invalid start byte

注意：我手动添加cl.exe到 PATH 变量中，因为我无法开始vcvarsall.bat x64工作。

关于如何解决这个问题的任何想法？我正在使用 python 3.6：line_profiler 是否仅适用于 python 2.X？
