错误：EACCES：权限被拒绝，mkdir '/usr/local/lib/node_modules/node-sass/build'

Question

I am trying to run an Angular application. I execute the ng serve command, but it then shows:

Error: Cannot find module 'node-sass'

Answer 1

Solution:

You need to change the ownership of folder node_modules , because you use sudo npm install -g node-sass , so its ownership is set to root.

To change the ownership to the current user as group -

sudo chown -R root:$(whoami) /usr/local/lib/node_modules/

sudo chmod -R 775 /usr/local/lib/node_modules/

And never use sudo for an npm -related query.

Answer 2

运行此命令

sudo npm install -g <ModuleName> --unsafe-perm=true --allow-root

Answer 3

Try this

sudo npm install -g --unsafe-perm node-sass

Or this

sudo npm install -g --unsafe-perm --verbose @angular/cli

Answer 4

I was working in Ionic and had this issue, so I solved this by moving one folder back and running this command:

sudo chmod -R 777 project-directory

And after this:

npm install node-sass --save

Answer 5

This is due to the user's permission. The user from which you are running the command of npm install is probably doesn't have permission. So you are getting errors.

For that user just give the permission for that project folder. In Mac , use the below steps and give read and write permission to the user for that project folder

• On your Mac, select a disk, folder, or file, and then choose menu File → Get Info .

• If the information in Sharing & Permissions isn't visible, click the arrow.

• If the lock at the bottom right is locked, click it to unlock the Get Info options, and then enter an administrator name and password.

• Click a user or group in the Name column, and then choose a privilege setting from the pop-up menu.

  • Read & Write: Allows a user to open the item and change it.

  • Read-only: This allows a user to open the item but not change its contents.

  • Write only (Drop Box): Makes a folder into a drop box. Users can copy items to the drop box, but can't open it. Only the owner of the dropbox can open it.

  • No Access: Blocks all access to the item.

This helped me to solve the problem.

Answer 6

This worked for me -

sudo chown -R `whoami` ~/.npm
sudo chown -R `whoami` /usr/local/lib/node_modules

Answer 7

If you have not added Node.js pakage.json yet, try running node init . If you already have this, npm install node-sass .

If both are present and you are using Ubuntu , try changing the permission of the folder using chmod -R <path to node module> .

Answer 8

Try this: npm install node-sass@version

If you want the latest, then just try npm install node-sass .

If you're getting an access problem then:

1. Windows: command prompt in administrator mode, and then run the above.

2. Mac:

    sudo npm install node-sass

References

• ERROR in Cannot find module 'node-sass'

• Windows: 'npm install node-sass' fails when module 'install.js' cannot be found. #603

Answer 9

Make sure you are not in the home directory or other places. You need to go back to root.

Use this command

cd ..
cd ~

Your current location should look like:

~$

After this, run the command to create a project.

Answer 10

u need to use a "root" user in your shell,

with this command:

sudo su -

then you should enter your password

and then try to install the package, i think it will work with any package that you try to install globally
