ImportError:没有名为build\u lib的模块

Question

我正试图以这种方式运行pip install命令：pip install pyverdict --upgrade，但出现以下错误：ImportError: No module named build_lib。我如何解决这个问题？ 更详细的错误：

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.
