Can't install ssh2 node module

Question

I try to install ssh2 from https://github.com/mscdex/ssh2 by issuing command sudo npm install ssh2. But it shows errors as follows:

ERR! Error: No compatible version found: ssh2

I am using nvm and node v0.10.13, but in the error it shows that i'm currently using node v0.6.19.

node -v
v0.10.13

What happen?

Answer 1

Try without sudo: npm install ssh2

Answer 2

Yes, the error is that ssh2 requires node >=0.8.7 and your PATH and/or nvm setup is causing you to execute an old version of npm running under node v0.6. That is definitely the problem. Fix it by installing and correctly executing a specific version of npm with a full filesystem path instead of just npm and it will work.
