I can't download selenium because of Permissions

Question

I'm trying to install selenium, but it says I can't do it because of permissions.By the way I'm doing that on MacOS Mojave 10.14

I just entered ''brew reinstall selenium-server-standalone''and then it fails cause of permissions, you can see that in code part.

==> Caveats
To have launchd start selenium-server-standalone now and restart at login:
  brew services start selenium-server-standalone
Or, if you don't want/need a background service you can just run:
  selenium-server -port 4444

Answer 1

It's suggesting pip install --user selenium

To fix this, the homebrew docs suggest the following :

Note on pip install --user The normal pip install --user is disabled for brewed Python. This is because of a bug in distutils , because Homebrew writes a distutils.cfg which sets the package prefix.

A possible workaround (which puts executable scripts in ~/Library/Python/<X>.<Y>/bin ) is:

python -m pip install --user --install-option="--prefix=" <package-name>

Answer 2

First, run:

brew clean all && brew doctor

It looks like you're using the system Python instead of the homebrew one, so it may benefit you to:

brew install python

And make sure that /usr/local/bin is before /usr/bin in your $PATH environment variable.
