# Plugin fail to install

![Blocking at around 90% of the installation process](/files/-M-JwB_syqTgQjRq-cP8)

### Coraye require a specific folder to be accessible

You may create or unlock a specific folder that is used by Coraye to install dependencies. This folder is `/usr/local/lib`.

**Does the folder exist ?**

To check if the folder exist you will need make a specific command into your **terminal** (Space + Cmd then ask for "terminal"). The command you will need to enter is :

`sudo mkdir /usr/local/lib` 

Then your password will be required, so enter it. What have we done :

* **sudo** mean "as an admin, please do the following command".
* **mkdir** mean "create this folder if it does not exist yet
* **/usr/local/lib** is the folder we want to create/check that it exist

**Does we have the right to read & write inside the folder ?**

To allow Coraye to write and read inside the folder we will do a second and final command inside our terminal :

`sudo chmod ugo+rw /usr/local/lib`

This time it won't ask for your password since you already enter it. \
With this last command what have we done :

* **sudo** still mean "as an admin, please do the following command".
* **chmod** mean "change the folder access right to..."
* **ugo+rw** mean "... read and write mode"
* **/usr/local/lib** is the folder we want to read and write in

Now you can quit Coraye that should be still be blocked (Force exit if needed) then re-start it.

And we're done 🎉
