@Michaeljurado24 thanks for reporting the issue. Can you please collect a strace of the failing command and share it out so that we can see where things are broken? To collect a trace "strace -o <trace_file> -ff <failing_command>". Also, just FYI there are have been considerable improvements made to this feature, which are not available in general public release. Currently, they are only available in the Windows Insider builds, but will eventually make it to general release.

Okay So the command works now ( I have no clue why).

The terminal output is as follows with some highlighted areas

But, i still can't install certain cpan modules even so.
For example, I recently tried to install the Finance::Robinhood module on cpan:
https://metacpan.org/release/Finance-Robinhood
using this command 'sudo cpanm Finance::Robinhood' but it could not complete it saying that

Also, Thank you all for developing this great service!!!!

This looks like a duplicate of #186. Follow the steps there to set dont_use_nlink => defined; and this will start working.
This appears to be fixed without the need for that change in current Insider build, see #910 .

[Michaeljurado42]

Thank you. I edited the config file and the problem went away. Thanks!
