Python rpy2 Package Installation problem Resolution

In Python direct pip install Rpy2, error, not carefully read the error, directly downloaded the WHL file (https://www.lfd.uci.edu/~gohlke/pythonlibs/) to install.

You can import rpy2 at this time, but you will be prompted with the import rpy2.robjects "Rpy2 error Wac-a-mole:r_user not defined", the workaround:

1. Add R.dll to the system path (for example, mine is C:\Program files\r\r-3.4.4\bin\x64);
2. Add environment variable R_home (I am C:\Program files\r\r-3.4.4);
3. Add the environment variable R_user, which is the user name (for example, I am administrator).

At this time again import rpy2.robjects, through, problem solved.
