Error: EACCES: permission denied, access '/usr/local/lib/node_modules'
Solution 1:
Change your file permissions... Like this
First check who owns the directory
ls -la /usr/local/lib/node_modules
it is denying access because the node_module folder is owned by root
drwxr-xr-x 3 root wheel 102 Jun 24 23:24 node_modules
so this needs to be changed by changing root to your user but first run command below to check your current user How do I get the name of the active user via the command line in OS X?
id -un OR whoami
Then change owner
sudo chown -R [owner]:[owner] /usr/local/lib/node_modules
OR
sudo chown -R ownerName: /usr/local/lib/node_modules
OR
sudo chown -R $USER /usr/local/lib/node_modules
Solution 2:
To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, you will create and use a hidden directory in your home directory.
Back up your computer. On the command line, in your home directory, create a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
In your preferred text editor, open or create a
~/.profile
file and add this line:
export PATH=~/.npm-global/bin:$PATH
On the command line, update your system variables:
source ~/.profile
To test your new configuration, install a package globally without using sudo
Solution 3:
All you need to do is to add USER to the owner of /local/lib
sudo chown -R $USER /usr/local/lib
EDIT :
To target precisely and only the node_modules folder, try using this command before using the previous one :
sudo chown -R $USER /usr/local/lib/node_modules
Solution 4:
I tried the solution of the answer given by @okanda but it didn't work for me.
However it worked perfectly when I did it for several folders like mentioned in this thread: https://github.com/angular/angular-cli/issues/9676#issuecomment-464857493
sudo chown -R $USER /usr/local/lib/node_modules/
sudo chown -R $USER /usr/local/bin/
sudo chown -R $USER /usr/local/share/
Solution 5:
try appending sudo before whatever command you are trying.
like this : sudo npm install
Using sudo with a command in Linux/UNIX generally elevates your permissions to superuser levels. In Windows, the superuser account is usually called 'Administrator.' In Linux/Unix the superuser account is generally named 'root'.
The root user has permission to access, modify or delete almost any file on your computer. Normal user accounts can access, modify or delete many fewer files. The restrictions on a normal account protect your computer from unauthorized or harmful programs or users. Some processes require you to perform actions on files or folders you don't normally have permissions to access. Installing a program that everyone can access is one of these actions.
In your case, running the installation command with sudo gives you the permissions of the superuser, and allows you to modify files that your normal user doesn't have permission to modify.
