试图在我的Ubuntu上安装djnago，但我没有这样做 . 我想这是因为我在Ubunutu上有python 2/7和python 3：

pip3 install django
Traceback (most recent call last):
  File "/usr/local/bin/pip3", line 5, in <module>
    from pkg_resources import load_entry_point

    dists = ws.resolve(reqs, Environment())
  File "/home/itaybz/.local/lib/python2.7/site-packages/pkg_resources/__init__.py", line 784, in resolve
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'pip==9.0.1' distribution was not found and is required by the application

以下是安装在ubunuto上的：
