我有很多问题，我不懂python及其不同的版本。 我正在做一个CS50 Web在线课程，我需要pip3用于python 3.6或更高版本。 情况是我不能使用pip for python 3.6。
在/usr/local/bin下，我可以找到不同的pip文件：pip，pip2，pip2.7，pip3和pip3.4。 无论如何，如果我运行"pip"，我收到消息bash：

/usr/local/bin/pip: /usr/bin/python: defect interpreter. File could
been not found.

如何在python3.6版本中使用pip命令？
对于课程项目，我应该使用"pip3 install -r requirements.txt"，其中requirements.txt包含以下项目：

我尝试使用"python3.6 -m pip install -r requirements.txt"，我得到以下消息：
