python module installation problems encountered and solutions

 

 Want a word cloud, when writing code, you need to install wordcloud module, run after installation, incorrect report:

  moudule 'pip' has no attribute 'main'

Baidu most questions, findings may be due to pip10 version no 'main', so I searched for a downgrade of several methods, one of which is:

  python -m pip install --upgrade pip==9.0.3

After the error again:

  ModuleNotFoundError:No module named 'matplotlib'

In the absence of prompt matplotlib module, but I run "pip install matplotlib" Without this module, also had this problem before, the settings can also be directly mounted display search:

    

 

 So https://www.lfd.uci.edu/~gohlke/pythonlibs/ download matplotlib of whl file to start the installation:

  1. Open cmd, input python -m pip install matplotlib.whl

  2. After another error as shown:

   

   3. Enter the python -m pip install --upgrade pip updated version pip

Question everyone you meet is not the same, the same error may be caused by different circumstances, require specific analysis of specific issues.
