Getting a permission error when installing with bower

问题

Everytime I try to install something with Bower I get a permission error like this:

Andreass-MacBook-Air:openMedia Andreas$ bower install jquery
/usr/local/lib/node_modules/bower/node_modules/configstore/index.js:56
            throw err;
                  ^
Error: EACCES, permission denied '/Users/Andreas/.config/configstore/bower-github.yml'
You don't have access to this file.

I imagine there might be an easy solution to this. But this is my first experience with Bower. Thanks in advance.

回答1:

Tried with sudo ?

sudo bower install --allow-root
sudo bower install jquery

Another solution is to change the chown of your configstore folder

sudo chown -R Andreas:Andreas /Users/Andreas/.config/configstore/
bower init
bower install jquery

If there are more errors with eaccess, expand the chown to your whole home folder

回答2:

Here is the fix, run below commands. it should work.

sudo chown -R $USER:$GROUP ~/.npm
sudo chown -R $USER:$GROUP ~/.config

回答3:

Change the json bower configuration file .bowerrc which looks like

{
    "directory": "www/lib"
}

to look like

{
    "directory": "www/lib",
    "allow_root": true
}

回答4:

you can just copy and paste this on your terminal

sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
