尝试在 Python 3.6.0 :: Anaconda 4.3.0（64 位）中安装 html5lib-1.1-py2.py3-none-any.whl 时遇到以下错误。
C:\Users\xyz\Desktop\Module>pip install html5lib-1.1-py2.py3-none-any.whl
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
