If you get an EACCESS error, the simplest way to fix this is to rerun the command, in either of the following ways:
- On unix shells, prefix the command with sudo
sudo npm install --global javascripting
- On Windows and if using either PowerShell or CMD, ensure you open the shell with administrator privilege.
You can also fix the permissions so that you don't have to use sudo. Take a look at this npm documentation:
