Re^2: Using Perlbrew macOS impossible to install distributions

Maybe you can solve my next problem too. If I want to install a new module, it fails saying that there is no permission to write in target folder. I do not see any special setting in my osMac that should prevent it. perl -v confirms I am working with the Perl version installed with Perlbrew.

Just one more comment in addition to kevbot's excellent post: `You are not allowed to write into directory "/Users/ad/.cpan/sources/authors"` This can also mean that a user other than `ad` has been working in that directory, for example if one has done `sudo cpan` in the past. If you still have the permissions problem after you've sorted out the confusion with the `/Users/ad` vs. `/Users/fc`, the simplest thing (although it'll cause a bit of re-downloading) is probably just to clobber the entire `.cpan` directory, making sure to back up the configuration file if you have set up a custom configuration. You may have to do `sudo rm`, but of course be very careful with this command!	[reply] [d/l] [select]

This output looks strange to me. It appears that there are two different user accounts involved (`/Users/ad` and `/Users/fc`). It appears that you are trying to run the cpan command when you are logged into the ad account, but you installed the brewed perl in the fc account. Is that the case? I always use brewed perls from the same account that I used to install them. Try to confirm that you are using the `cpan` executable from your brewed perl. Typing this at the command line, `which cpan` [download] should give you output like this, `/Users/fc/perl5/perlbrew/perls/perl-5.26.1/bin/cpan` [download] If the output is `/usr/bin/cpan`, then you are still using the cpan command that is part of the system perl. After you installed `perl-5.26.1` did you switch to it with the following command? `perlbrew switch perl-5.26.1` [download] If you did not run the switch command then you are still using the system perl (which is probably not what you want). Once you confirm that you are using your brewed perl, I recommend that you install `cpanminus` (see App::cpanminus) using the following command, `curl -L https://cpanmin.us \| perl - App::cpanminus` [download] Then you can use `cpanm` to install modules (I find that its easier to use than the older `cpan` command).

My error: I just erroneously changed fc->ad when I was editing my post (sorry). I was using the correct perl and can was the one supposed to be Again, your suggestion saved my day. After installing cpanminus I can install the modules like a breeze. THANK YOU	[reply]
