Attempt to install Amber.js on OS X fails because grunt client not installed?

Question

I have installed node.js and npm on my OS X box running 10.11.5. But, following the instructions at http://docs.amber-lang.net/getting-started.html, when I type:

npm install -g amber-cli

in the Terminal, I get the following result:

npm WARN amber-cli@0.100.2 requires a peer of grunt-cli@^0.1.13 but none was installed.

And the installation halts. Since this is only a warning from npm, I wonder if I really need grunt installed.

FWIW, it does appear I have a version of grunt in my npm directory because using locate to find it produces a billion lines, one of which is:

/Users/me/.npm/grunt

In fact, it looks like I have a bunch of grunt installs (most version 0.4.0). Which makes me reluctant to install grunt again since it doesn't seem to work anyway.

Answer 1

More than likely, it's a problem with your path.

If nothing returns when you execute which grunt, it means that you need to add the location of grunt to your path.

If you installed grunt using npm install -g, you'll need to add /usr/local/bin to your path.

Since you found your grunt cli under ~/.npm, you will need to add that to your path.

You should also add ./node_modules/bin to your path which will cause your shell to check for npm-installed modules in the node_modules/bin directory in your current directory.

You can always run grunt directly, irrespective of its location, by typing: npx grunt using the tool included with npm for running npm-installed commands.

It's good practice to add all of the paths above, to catch all possible npm-installed commands.

You can update your path in the ~/.*rc file for your shell (~/.bashrc for bash, etc.), by adding this line to the end of your rc file:

export PATH=/usr/local/bin:~/.npm:./node_modules/bin:$PATH

Try the following command

npm install -g grunt-cli@0 grunt-init bower amber-cli
