if i show global dependencies, i have @angular/cli... so, why this error ?, what im doing wrong ?.

searching on stackOverflow, i decide install node-pre-gyp, and install xCode. but, nothing change.

Answer 1

Well I did this and it worked for me.

1. rm -rf /usr/local/lib/node_modules
2. brew uninstall node
3. brew install node --without-npm
4. echo prefix=~/.npm-packages >> ~/.npmrc
5. curl -L https://www.npmjs.com/install.sh | sh

6. add the following line to your ~/.bash_profile (export PATH="$HOME/.npm-packages/bin:$PATH")

7. Unistall your current @angular/cli (sudo npm uninstall -g @angular/cli)

8. npm cache clean --force / npm cache verify
9. xcode-select --install
10. npm install -g node-gyp
11. npm install -g @angular/cli (without sudo).

Let me know if it works

Answer 2

You're not doing anything wrong, there is some error related to (probably) fsevents, both official package from node.js (lts and current) and homebrew installs have this issue.

Follow answers on this thread: How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)

[basically you need to remove node, npm, ng files and folders manually]

and install nvm and then node with nvm.
