BadValue Invalid or no user locale set. Please ensure LANG and/or LC_* environment variables are set correctly

Question

When I run mongo, I get the warning:

Failed global initialization: BadValue Invalid or no user locale set. Please ensure LANG and/or LC_* environment variables are set correctly.

Solution 1

Generating locales

Missing locales are generated with locale-gen:

locale-gen en_US.UTF-8

Alternatively a locale file can be created manually with localedef:[1]

localedef -i en_US -f UTF-8 en_US.UTF-8

Setting Locale Settings

The locale settings can be set (to en_US.UTF-8 in the example) as follows:

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
locale-gen en_US.UTF-8
dpkg-reconfigure locales

The dpkg-reconfigure locales command will open a dialog under Debian for selecting the desired locale. This dialog will not appear under Ubuntu. The Configure Locales in Ubuntu article shows how to find the information regarding Ubuntu.

Solution 2

you can use the below command on terminal

export LC_ALL=C

Solution 3

vim /etc/default/locale

add to it:

LC_ALL="en_US.UTF-8"

Solution 4

Amazon Linux AMI

Permanent solution for ohmyzsh:

$ vim ~/.zshrc

Write there below:

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

Update changes in current shell by: $ source ~/.zshrc

Solution 5

adding the following lines to my /etc/environment file worked

LC_ALL=en_US.UTF-8
LANG=en_US.UTF-8

To have it in all seasons : echo "export LC_ALL=C" >> ~/.bashrc

The other answers are not permanent solutions. We have to enter those commands each time we connect. Edit that file only once is the perfect solution! Thank you

Only execute on your terminal. not server

This is the only permanent solution that worked for me. Definitely deserves more upvotes!

This way just for current seesion, Just for one time, Not for forever!

Worked. Importing thing to note is that you need to logout and login again in order for this to work.

hi, I have accidently downvoted this question and missed it. Now I cannot remove it. It says my vote is locked. I 'am really sorry. If there is any other way, let me know.
