npm | 用户文件夹上的node_modules

Question

I'm little bit confused after try to solve how to install a module globally using npm.

I installed Node using a .dmg package from official site. This is the final log.

Node was installed at

/usr/local/bin/node

npm was installed at

/usr/local/bin/npm

Make sure that /usr/local/bin is in your $PATH.

From terminal I normally install modules using: for eg

npm install -g bower or npm install bower

But, I never could use

 bower
 -bash: bower: command not found

So I looked for

npm prefix
/Users/cleliodpaula
npm prefix -g
/Users/cleliodpaula/.node

npm ls
/Users/cleliodpaula
├─┬ appbuilder@2.1.1-61

How I can Install properly the Node, NPM and their modules?

edit:

I already installed it. But the installed bower, are not in the

/usr/local/bin

but, int the:

/Users/cleliodpaula/.node/bin/

Answer 1

Bower is not part of NPM, you need to install it separately:

npm install -g bower

Then you will have the executable in /usr/local/bin/bower and you will be able to use the bower command in Terminal.

The difference between npm install -g and npm install is that npm install -g installs the module globally (executable will be placed into /usr/local/bin ). If you just use npm install , then NPM will install the package into node_modules directory under the current one. In that case you can execute the command as ./node_modules/bower/bin/bower .

Edit: As I can see your NPM global path is set to /Users/cleliodpaula/.node/bin/ . If you want packages to be installed in /usr/local/bin , then change the configuration of NPM:

npm config set prefix /usr/local

You can also add /Users/cleliodpaula/.node/bin/ if you prefer packages to be installed in /Users/cleliodpaula/.node/bin/ :

export PATH=/Users/cleliodpaula/.node/bin/:$PATH

Answer 2

SOLVED:

Install Command Line Tools + Open Xcode. The npm and node wasn't installed properly because that.
