Issues installing node modules on Windows 10 machine

Question

I'm having an issue installing any modules onto my windows 10 machine, following a fresh nodejs install.

Its my laptop, so I have full access etc.

I have looked across numerous forums, and there doesn't seem to be a definitive answer to this issue.

The npm-debug returns the following:

0 info it worked if it ends with ok
1 verbose cli [ 'C:\\Program Files\\nodejs\\node.exe',

1 verbose cli   'C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js',

Any help would be brilliant.

Answer 1

You're using an old version of npm (3.10.10). I'd recommend updating to the latest (as of this post - 4.4.1 stable):

> npm install -g npm

Or if the above fails:

> npm update -g npm

If you still have a problem, you can try:

> npm config set ca ""

Or (which I'd discourage but should at least confirm the problem):

> npm config set strict-ssl false

As a side note, much of the information you posted is irrelevant. The main problem is found near the end of the output. You seem to be having an SSL issue.
