The direnv binary is now available in:
|
||
|
|
|
||
|
|
$bin_path/direnv
|
||
|
|
|
||
|
|
The last step is to configure your shell to use it. For example for bash, add
|
||
|
|
the following lines at the end of your ~/.bashrc:
|
||
|
|
|
||
|
|
eval "\$(direnv hook bash)"
|
||
|
|
|
||
|
|
Then restart the shell.
|
||
|
|
|
||
|
|
For other shells, see https://direnv.net/docs/hook.html
