npm not ok
System prompts that node and npm versions are incompatible. Maybe it's a problem that the apt-get source has not been updated.
2. Download the source code from github and install it successfully
Below you need to find a compatible version and install it manually.
Uninstall the newly installed node and npm first
The code copy is as follows:
~ sudo apt-get autoremove npm
~ sudo apt-get autoremove nodejs
Find the official release download of nodejs: https://github.com/joyent/node
In ubuntu, install git first
Copy the code as follows: ~ sudo apt-get install git
Then, download the nodejs source code from github
Copy the code as follows: ~ git clone git://github.com/joyent/node.git

Enter the node directory
Copy the code as follows: ~ cd node
~ pwd
/home/conan/workspace/nodejs/node
Switch the latest release version v0.11.2-release
Copy the code as follows: ~ git checkout v0.11.2-release
Branch v0.11.2-release set up to track remote branch v0.11.2-release from origin.
Switched to a new branch 'v0.11.2-release'
Carry out installation
Copy the code as follows:./configure
Make
sudo make install
Installation is complete, view node version
Copy the code as follows: ~ node -v
-bash: /usr/bin/node: No such file or directory
The prompt is error, the node is not found, check the node installation location
Copy the code as follows: ~ whereis node
node: /usr/local/bin/node
Add soft links: node and npm to /usr/bin
Copy the code as follows: ~ sudo ln -s /usr/local/bin/node /usr/bin/node
~ sudo ln -s /usr/local/bin/npm /usr/bin/npm
Let's check the node and npm versions again
Copy the code as follows: ~ node -v
v0.11.2
~ npm -v
1.2.21
Install express below
Copy the code as follows:~ sudo npm install express -g
[email protected] /usr/local/lib/node_modules/express
├── [email protected] ([email protected])
└── [email protected] ([email protected], [email protected], [email protected], [email protected], [email protected], [email protected])
Installation was successful.
3. Establish an express project and start the first project
The code copy is as follows:
~ express -e nodejs-demo
create : nodejs-demo
create : nodejs-demo/package.json
create : nodejs-demo/app.js
create : nodejs-demo/public
create : nodejs-demo/public/javascripts
create : nodejs-demo/public/images
create : nodejs-demo/public/stylesheets
create : nodejs-demo/public/stylesheets/style.css
create : nodejs-demo/routes
create : nodejs-demo/routes/index.js
create : nodejs-demo/routes/user.js
create : nodejs-demo/views
create : nodejs-demo/views/index.ejs
install dependencies:
$ cd nodejs-demo && npm install
run the app:
$ node app
Install dependency package
Copy the code as follows: ~ cd nodejs-demo
~ sudo npm install
[email protected] node_modules/express
├── [email protected] ([email protected])
└── [email protected] ([email protected], [email protected], [email protected], [email protected], [email protected], [email protected])
Start the program
Copy the code as follows: ~ node app.js
