在MAC上安装后出现角度倾斜错误

Question

I'm trying to install the MEAN stack on my Mac Book Pro. I'm getting an error consistently after install node and angular-cli.

when running the command 'ng help, or ng -v' I get the error: "ng help -bash: ng: command not found" .

Here are my specs: node -v v6.11.3 npm -v 3.10.10 MAC Sierria 10.12.6

I've tried several steps in forums and uninstalling and reinstalling node and npm several times.

Also, I've tried installing and uninstalling from BREW. I keep getting the same error though.

Is there a correct way to install the MEAN stack on a MAC? Specifically for the issue I'm experiencing with the angular-cli?

Also, I've set permissions to my npm folders according to this site: https://docs.npmjs.com/getting-started/fixing-npm-permissions

Answer 1

it looks like you do not have @angular/cli installed globally. Use -g flag to install it globally:

npm i @angular/cli -g

to check your globally installed packages run:

npm ls -depth 0 -g

if your list is very long, you can narrow it with grep :

npm ls -depth 0 -g | grep angular

make sure that you have angular CLI listed there.

I personally prefer installing angular CLI locally per project and accessing it via node_modules/.bin :

node_modules/.bin/ng -v

Found this here: https://github.com/angular/angular-cli/issues/5021 Worked for me.

npm install -g @angular/cli

Make sure the ng path is correct
    cd ~/npm-global/bin
    ls and make sure ng exists

create .bashrc file on your home directory
    touch ~/.bashrc
    vim ~/.bashrc

Add ng as alias
    press a (enables edit mode) then type in the following
    alias ng="~/npm-global/bin/ng"
    press esc (to get out of edit mode) then :wq (in vim will save)

Temporarily Update .bashrc reference
Your terminal wont take bash updates until a restart but the following command will let you use the updates during the terminal session:
    source ~/.bashrc

Check that ng works
    ng --version

Answer 3

npm install -g @angular/cli

https://github.com/angular/angular-cli/blob/master/README.md

if you have problem with your node, you may need nvm
