Dear Team:
I have a problem with my virtualenv and this library the page that use this library show me the following error "ModuleNotFoundError No module named 'matplotlib" I have it installed in the server but not in my virtualenv I tried to install it again but I have problem with the instalation, the bash console show me this message "Defaulting to user installation because normal site-packages is not writeable"
I also tried to install it into viertualenv folder with same result I also try to install it with this command "python -m pip install -U matplotlib" this install it, the libray again but not in my virtualenv folder
My last chance was to install it indicating the folder in which I want install the library but, unfortunately don't work for folder permission ( i dont know why because give to all folder 777 permision)
would you mind telling me how to install the library in my virtualenv
regards
