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'm working on a OSX 10.10.4, I have worked with node.js and express before on this computer.
But now when I want to start a new application, the computer won't recognize the command express anymore.
I've tried installing it with all these commands:
- npm install express
- npm install -g express
- npm install express -g
- sudo npm install -g express
- sudo npm install express -g
- npm install express-generator
- npm install -g express-generator
- npm install express-generator -g
- sudo npm install -g express-generator
- sudo install express-generator -g
- sudo npm install -g express-generator#3
- sudo npm install -g express-generator#4
But it still doesn't recognize the command express
This is the output when I install without the -g
npm install express

I have tried some other stuff like the PATH and nodejs-legacy, but none of them work.
With the sudo apt-get install nodejs-legacy the computer doesn't find the command apt-get.
The reason I got express:command not found after I installed was because my $PATH didn't know where express was.
To anyone wanting to install the express command line tools I did this
sudo npm install express-generator -g
which resulted in
/usr/local/share/npm/bin/express -> /usr/local/share/npm/lib/node_modules/express-generator/bin/express

when I tried express --version I got a command not found
Open your bash_profile from terminal with open ~/.bash_profile
After that add the path you got after you installed express, in my case it was
/usr/local/share/npm/lib/node_modules/express-generator/bin/express
Add this to your bash_profile
export PATH=/usr/local/share/npm/lib/node_modules/express-generator/bin:$PATH
Save the file and go back to terminal. Enter hash -r and then quit terminal and start it again.
Now if you try express --version for example you should see that the command line tools are working.
There's kind of a mishmash of problems you're describing here, so I'll try to address them one at a time.
Express is a popular framework for node.js. The typical way to add it to your project is to do npm install --save express and then it will save it into your package.json file and install it into node_modules. Adding -g to that command would attempt to install it globally, but that's not how express is used. Express is used on a per-project basis. See their website for details.
In the big list of commands you've run, you mention express-generator. Express-generator is a tool that lets you quickly build out some boilerplate to make starting an express project a bit easier. Since express-generator is meant to be run globally and not inside a project, you DO install it with the -g flag. See their website for details on use and installation.
You're trying to install some more node stuff with the apt-get command. That command is used for package management on Linux (typically Ubuntu/Debian) machines. Mac OS X doesn't come with it (and you absolutely don't need it). Any instructions that mention running apt-get are not targeted towards Mac users.
Essentially, I don't think you have a problem, the logs you show are exactly what I'd expect to see. Generate a boilerplate project with express-generator and you should be all set to start working on your express project. Good luck!
I run the following command in my bash and I get the related results:
merianos#merianos-desktop:~$ sudo npm install -g grunt-cli

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
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
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

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.
