尝试在 OS X 上安装 Amber.js 失败，因为没有安装 grunt 客户端？

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

试试下面的命令

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

Answer 2

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
