Question

Deprecated version of express doesn't upgrade

Posted November 24, 2014 3.9k views

The version of express in the MEAN stack remains 2.5.8 which is supposed to be deprecated. How do I get it to release 3.x.x or higher ?

I have tried

npm install -g express@3.x.x

and the feedback is that it is installing 3.18.4

/usr/local/bin/express -> /usr/local/lib/node_modules/express/bin/express 
express@3.18.4 /usr/local/lib/node_modules/express

but then after successful install still version 2.5.8 is shown

root@olivettatest:~/projects/getting-MEAN# express --version 
2.5.8

Anybody any Idea ?

What’s the output of which express ? You seem to have another version installed somewhere on your PATH I suspect you may have installed the version directly from the Ubuntu repositories.

The MEAN sample project installed to /opt/mean on the DigitalOcean one-click app currently installs express 4.9.7:

head -n 1 /opt/mean/node_modules/express/History.md 
4.9.7 / 2014-10-10

With express >= 4.0 the command line tool has move to the express-generator package. It can be installed with:

npm install -g express-generator

Here’s the output of that command:

/usr/local/bin/express -> /usr/local/lib/node_modules/express-generator/bin/express
express-generator@4.9.0 /usr/local/lib/node_modules/express-generator
├── mkdirp@0.5.0 (minimist@0.0.8)
└── commander@1.3.2 (keypress@0.1.0)
root@mean-test:/opt/mean# which express
/usr/local/bin/express
root@mean-test:/opt/mean# express --version
4.9.0
