How to fix a locale setting warning from Perl?

Question

When I run perl, I get the warning:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset         


        

Answer 1

With zsh ohmyzsh I added this to the .zshrc:

 # You may need to manually set your language environment
 LANGUAGE=en_US.UTF-8
 LANG=en_US.UTF-8
 LC_CTYPE=en_US.UTF-8
 LC_ALL=en_US.UTF-8

By removing the line export LANG=en_US.UTF-8

Reopened a new tab and SSHed in, worked for me :)

Answer 2

on Debian after much searching this did the trick.

first:

sudo apt-get purge locales

then:

sudo aptitude install locales

and the famous:

sudo dpkg-reconfigure locales

This rids the system of locales, then re-installs locales and downgrades libc6 from 2.19 to 2.13 which is the issue. Then configures locales again.

Answer 3

All the previous answers are wrong. The message is clear - missing locale. The solution is to add the appropriate locale. You do that by editing the /etc/locale.gen file, remove the # sign in front of the locale being reported as missing and then issuing the command:

$ sudo locale-gen

This will actually generate the locales specified in /etc/locale.gen and therefore the message will not be shown.

Answer 4

For Ubuntu use this,

#export LANGUAGE=en_US.UTF-8
#export LC_ALL=en_US.UTF-8
#export LANG=en_US.UTF-8
#export LC_TYPE=en_US.UTF-8

Worked for me.

Answer 5

perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_ALL to default locale: No such file or directory

Solution:

Try this (uk_UA.UTF-8 is my current locale. Write your locale, for example en_US.UTF-8 !)

sudo locale-gen uk_UA.UTF-8

and this.

sudo dpkg-reconfigure locales

Answer 6

Add LC_ALL="en_GB.utf8" to /etc/environment and reboot. That's all.
