cpan error: Unable to get Terminal Size. The Win32 GetConsoleScreenBufferInfo call didn't work

Question

ActiveState Perl - 5.26 on Windows 10 - 64 bit.

When I am trying to launch cpan from CMD - I see the following error:

C:\Users\orenm>cpan
Unable to get Terminal Size. The Win32 GetConsoleScreenBufferInfo call didn't work. The COLUMNS and LINES environment variables didn't work. at C:\Perl64\lib/Term/ReadLine/readline.pm line 410. 

Why does it happen? What shall I do with it?

Answer 1

It's trying to figure out your terminals size. You can use a 'dumb' terminal.

set TERM=dumb

will eliminate the warning.

This is a reasonable work around, but it seems like the builders of Win versions of perl (Strawberry in my case) aren't including common sense Windows perl modules that are in cpan to their distributions as a default. – Swaraj

Answer 2

In PowerShell the equivalent syntax is

$env:TERM="dumb"
