安装MAC OS X El Capitan后出错

Question

I have NodeJS installed on my mac.

$ node -v
v4.2.1

I'm trying to install bower. Here is the result:

npm ERR! Darwin 15.0.0

I tried to do:

$ sudo chown -R $(whoami) ~/.npm
chown: /Users/Kevin/.npm/_locks: Operation not permitted
chown: /Users/Kevin/.npm/bower/1.6.3/package/package.json: Operation not permitted
chown: /Users/Kevin/.npm/bower/1.6.3/package: Operation not permitted
chown: /Users/Kevin/.npm/bower/1.6.3/package.tgz: Operation not permitted
chown: /Users/Kevin/.npm/bower/1.6.3: Operation not permitted
chown: /Users/Kevin/.npm/bower: Operation not permitted
chown: /Users/Kevin/.npm/n: Operation not permitted

It seems like I don't have permission at all. I can not install anything.

How can I fix that?

Answer 1

You can run the following commands in a terminal to fix this permission error.

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

Then you will no longer need to use sudo with any npm installs.

Answer 2

The only solution I found was to reinstall mac OS X El Capitan. After that it worked.

I'm now using docker to do not have this kind of problem again.
