While you can set the locale exporting an env variable  you will have to do that every time you start a session  Setting a locale this way will solve the problem permanently   sudo apt-get install locales sudo locale-gen en US UTF-8 sudo echo  LANG en US UTF-8   gt   etc default locale

The error message indicates a problem with the locale setting  To fix this as indicated by other answers you need to modify your locale   On Mac OS X Sierra I found that the best way to do this was to modify the   bash profile file as follows   export LANG  en US UTF-8  export LC ALL  en US UTF-8  export LC CTYPE  en US UTF-8    This change will not be immediately evident in your current cli session unless you reload the bash profile by using  source    bash profile   This answer is pretty close to answers that I ve posted to other non-identical  non-duplicate questions  i e  not related to pipenv  but which happen to require the same solution   To the moderator  With respect  my previous answer got deleted for this reason but I feel that was a bit silly because really this answer applies almost whenever the error is  problem with locale     but there are a number of differing situations  languages  and environments which could trigger that error   Thus it A  doesn t make sense to mark the questions as duplicates and B  doesn t make sense to tailor the answer either because the fix is very simple  is the same in each case and does not benefit from ornamentation

The root cause is  your environment variable LC ALL is missing or invalid somehow    Short answer-   just run the following command     export LC ALL C   If you keep getting the error in new terminal windows  add it at the bottom of your  bashrc file   Long answer-  Here is my locale settings     locale LANG en US UTF-8 LANGUAGE  LC CTYPE  C  LC NUMERIC  C  LC TIME  C  LC COLLATE  C  LC MONETARY  C  LC MESSAGES  C  LC PAPER  C  LC NAME  C  LC ADDRESS  C  LC TELEPHONE  C  LC MEASUREMENT  C  LC IDENTIFICATION  C  LC ALL C   Python2 7        uname -a     Linux debian 3 16 0-4-amd64  1 SMP Debian 3 16 7-ckt11-1 deb8u6  2015-11-09  x86 64 GNU Linux       python --version     Python 2 7 9       pip --version     pip 8 1 1 from  usr local lib python2 7 dist-packages  python 2 7        unset LC ALL       pip install virtualenv     Traceback  most recent call last         File   usr local bin pip   line 11  in  lt module gt          sys exit main          File   usr local lib python2 7 dist-packages pip   init   py   line 215  in main         locale setlocale locale LC ALL            File   usr lib python2 7 locale py   line 579  in setlocale         return  setlocale category  locale      locale Error  unsupported locale setting       export LC ALL C       pip install virtualenv     Requirement already satisfied  use --upgrade to upgrade   virtualenv in  usr local lib python2 7 dist-packages

Someone may find it useful  You could put those locale settings in  bashrc file  which usually located in the home directory  Just add this command in  bashrc  export LC ALL C then type source  bashrc Now you don t need to call this command manually every time  when you connecting via ssh for example
