 Set this variable in ``.bashrc`` or ``.zshenv`` to make it persistent.
 Alternatively, this option can be specified in ``pip.conf``, e.g.:

+
 .. code:: console
 
-    $ cat ~/.config/pip.conf
+    $ cat ~/.config/pip/pip.conf
     [global]
     constraint = /home/username/constraints.txt

+
+    $ cat $HOME\AppData\Roaming\pip\pip.ini
+    [global]
+    constraint = '$HOME\Roaming\pip\constraints.txt'

+The conf file are dependent of the user, so If you use multiple users you must define config file for each of them.
