Grunt安装错误：“应与-g一起安装”

Question

I'm trying to install Grunt on my machine. I have read some tutorials and followed the installation docs , but I can't get it working.

The CLI installs ok using this command:

sudo npm install -g grunt-cli

When I select a local directory (containing the package.json and Gruntfile) and npm install , I see the following message:

npm WARN prefer global grunt-cli@0.1.9 should be installed with -g

Why is this happening? I did install with -g - meaning 'globally', I understand.

After this, it seems that I cannot run grunt, eg:

$ grunt
-bash: grunt: command not found
$ grunt --version
-bash: grunt: command not found

How can I fix this? What am I missing?

Here is my full log:

Answer 1

You shouldn't use sudo to install package.
If you use sudo something went wrong when you installed node and npm.
I see that you use OSX so, trust me, install node with brew packet manager ( http://brew.sh ) and make it handle node and npm for you.

Remove node first and then just install Brew following the instruction. Then you can just type brew install node and everything works like a charm.

When you install your locale packages npm install , it's possible a package request grunt-cli as a dependency. Don't worry about it, this warning don't mean it broke anything.

The grunt: command not found mean that the grunt binary is not added to your Path. Add it and you'll be fine: https://unix.stackexchange.com/questions/26047/how-to-correctly-add-a-path-to-path

The path to add should be this one from the output of your terminal: /Users/tonyMac/.node/bin

In Bash: PATH=$PATH:/Users/tonyMac/.node/bin (if you run it in command line, then add export command before).
