For the past few weeks everytime I have downloaded a package using pip i get this: WARNING: Ignoring invalid distribution -ip (path to packages) . Any ideas why I get this?
This occurs due to files names with the '~' prefix in site-packages. Please remove those files / folders. It will solve your problem.
You can list them with
ls -a /xx/xx/xx/lib/pythonx.x/site-packages | grep "^~"`
Then remove files/folders prefixed by '~'.
go to 'site-packages' directory, delete folders whose name start with ~ (tilde)
This happens due to multiple versions installation of libraries, at times conda or pip failed to uninstall the versions instead rename it to "~ip" so, suggest we find site-packages in our python installation and search for "~ip" and delete such folders which begin with ~ip. Then the problem will get resolved and we will not get any such warnings. Otherwise, it is only a warning because of such folders existing in the installation that we can ignore.
