Just installed Node.js v.0.10.20 from source. Target box Ubuntu 12.04.3 LTS. Node is installing ok without errors. After all it seems :

node -v
v0.10.20

npm -v
1.3.11

But just listing my -g modules, I get some odd messages I can't figure out :

esa@fingolfin:~$ npm list -g
npm WARN unmet dependency /usr/local/lib/node_modules/npm/node_modules/normalize-package-data requires semver@'1.x' but will load
npm WARN unmet dependency /usr/local/lib/node_modules/npm/node_modules/semver,
npm WARN unmet dependency which is version 2.1.0

and at a bottom of -g listing, I see more messages :

npm ERR! invalid: [email protected] /usr/local/lib/node_modules/npm/node_modules/semver
npm ERR! extraneous: [email protected] /usr/local/lib/node_modules/npm/node_modules/normalize-package-data
npm ERR! not ok code 0

Also I can see under [email protected] -module the row:

│ ├── [email protected] invalid

This same happens in previous node version (0.10.18) if I remember that right.

Annoying message that I can't solve. I'm sure I haven't installed semver-module manually and quite sure that none of my installed node-modules is using semver.

Edit: thanks to Nirk, re-installing npm will solve this. To be sure, I gave sudo su - and re-installed as root. Maybe just sudo:ing works as well.

Here is what I did :

sudo su -

Note that URL has moved to https://npmjs.org/install.sh

You have an older version of normalize-package-data (the current version depends on semver version 2: https://github.com/meryn/normalize-package-data/blob/master/package.json#L15 )

To forcefully reinstall npm without using npm, try using the shell script

curl https://npmjs.org/install.sh | sh
