Python2 and 3 issues when using PIP

WIN10, the computer is equipped with Anaconda,python2. Because Python3 is needed, the Python3 is installed directly. Python3 the default path in the C drive. I moved it to the D drive and modified the two environment variables. The default Python version of the computer should be python3.

At this time, I think with PIP3 can be installed to python3 under, but there is a problem, said there is a space error. Don't understand

At this point, I use the PIP,PIP will be installed under the Python2.

There are several different workarounds:

1) Use command python pip.exe install yourpackage under your Python3 scripts.

The command for the PIP version update is given in the figure.

2) prefix (Not for me)

Run Python2:py-2 hello.py

Run Python3:py-3 hello.py

Similarly installed: py-2-m pip install xxxx or py-3-m pip install xxxx

3) python-m pip install Django (not for me)

4) Change Pip and Python.exe name
