I am new to node.js.
I have installed node.js and I tested the installation is ok. node -v and npm -v command are showing the version numbers.
But when I install any module it's not working.
For example when I try to install the connect module using npm install connect, it's showing following result.
C:\>npm install connect
connect#3.3.5 node_modules\connect
├── utils-merge#1.0.0
├── parseurl#1.3.0
├── debug#2.1.3 (ms#0.7.0)
└── finalhandler#0.3.4 (escape-html#1.0.1, on-finished#2.2.0)
C:\>
Kindly help me out.
That installed it. However it installed it "locally" (to the current folder) and not globally. If you want to install it globally then use -g.
npm install -g connect

I have tried any ways I can but still can't install express successfully.
I used
sudo npm install -g express-generator
sudo npm install -g express
The terminal shows
/usr/bin/express -> /usr/lib/node_modules/express-generator/bin/express
express-generator#4.13.1 /usr/lib/node_modules/express-generator
├── sorted-object#1.0.0
├── commander#2.7.1 (graceful-readlink#1.0.1)
└── mkdirp#0.5.1 (minimist#0.0.8)
But when I input express, it still says "command not find". I also added the path"/usr/lib/node_modules/express-generator/bin" in system path, it still failed.
I stuck this problem for two days, it's quite annoying. Please help me.
Try $ sudo npm cache clean and then install express and express-generator without sudo.
I run the following command in my bash and I get the related results:
merianos#merianos-desktop:~$ sudo npm install -g grunt-cli
/usr/local/bin/grunt -> /usr/local/lib/node_modules/grunt-cli/bin/grunt
grunt-cli#0.1.13 /usr/local/lib/node_modules/grunt-cli
├── resolve#0.3.1
├── nopt#1.0.10 (abbrev#1.0.7)
└── findup-sync#0.1.3 (lodash#2.4.2, glob#3.2.11)
and
merianos#merianos-desktop:~$ grunt
/usr/bin/env: node: No such file or directory
I also have try to install bower and gulp but again, when I try to execute them, I get a message related to the grunt above.
Can someone please help me ?
Just to know, I just installed Ubuntu 15.04. I don't know if that helps :)
Ubuntu package nodejs provide a binary as a /usr/bin/nodejs, not a /usr/bin/node, so most of cli tools can't find it. To solve the problem you need to make a symlink:
sudo ln -sT /usr/bin/nodejs /usr/bin/node
npm knows that grunt is installed globally, so why isn't it found?
$ npm install -g grunt
... installs ...
$ npm list -g | grep grunt
│ ├─┬ gruntfile-editor#0.2.0
│ ├─┬ gruntfile-editor#0.2.0
├─┬ grunt#0.4.5
│ ├─┬ grunt-legacy-log#0.1.1
│ ├── grunt-legacy-util#0.2.0
$ grunt
-bash: grunt: command not found
I assume because it's put it somewhere that is not on my PATH.
Why doesn't npm just put it somewhere that is on my PATH by default, like /usr/local/bin?
UPDATE: Weirdly, I get the same grunt: command not found error even after I do npm install grunt to run it locally. What am I doing wrong? There is a Gruntfile.js in my repo.
The package "grunt" is the task runner itself whereas the "grunt-cli" package is the command line interface that includes the grunt executable. You can make sure that it is installed to the correct path.
If you do npm install grunt-cli it still would not work because this would be installed to node_modules in the corresponding directory which is most likely not on your path. However, when you use grunt from the globally installed CLI tool it will look for an installation of grunt that is local to that project as well as the Gruntfile.js
what you have to do is
install grunt-cli globally:
$ npm install grunt-cli -g
install grunt local in your dependencies (optionally save the dependency to your package.json):
$ npm install grunt --save
For me there was another thing missing, adding the path to NPM's folder in Window's env variables
Go to System (My computer->Properties)
Advanced System Settings
In Advanced tab, 'Environment Variables'
Under User variables, choose Path, then Edit
Add this alongside the others you have: '%USERPROFILE%\AppData\Roaming\npm'
Hope this helps, g'luck
My node suddenly stopped working so I removed everything and installed node with homebrew.
Now I cant install grunt, nodemon, bower etc.
Pers-MacBook-Air:backendMD perstrom$ sudo npm install -g grunt-cli
Password:
/Users/perstrom/.node/bin/grunt -> /Users/perstrom/.node/lib/node_modules/grunt-cli/bin/grunt
grunt-cli#0.1.13 /Users/perstrom/.node/lib/node_modules/grunt-cli
├── resolve#0.3.1
├── nopt#1.0.10 (abbrev#1.0.5)
└── findup-sync#0.1.3 (lodash#2.4.1, glob#3.2.11)
Pers-MacBook-Air:backendMD perstrom$ grunt --version
bash: grunt: command not found
Pers-MacBook-Air:backendMD perstrom$
What can be wrong? How do I debug this?
Try to expend your path (make sure this folder contains the bins):
export PATH=/Users/perstrom/.node/bin:$PATH
I'm using NVM to avoid using sudo to install things globally. It works fine for everything from Bower, to Grunt, etc. However, when I do npm install -g express-generator it doesnt work. For example, heres what I get when I globally install Bower:
npm install -g bower
/Users/jrdillon522/.node/bin/bower -> /Users/jrdillon522/.node/lib/node_modules/bower/bin/bower
bower#1.3.12 /Users/jrdillon522/.node/lib/node_modules/bower

Works fine right? When I install the Express Generator I get the classic error:
npm ERR! Please try running this command again as root/Administrator.
So I run sudo npm install -g express-generator. Heres what I get then:
sudo npm install -g express-generator

Why??
It looks like your bin path (/Users/myName/.node/lib/node_modules/express-generator/bin/express) isn't added to your environment.
If you modify your .bashrc file, add the following line to the bottom of your file to make things work as expected:
export PATH=$PATH:/Users/myName/.node/lib/node_modules/express-generator/bin
Then retry the installation.
