Answer 1

Do you use a proxy? and did you find these entry here seems to be the same problem with an other module. https://github.com/npm/npm/issues/8048

I had similar errors

npm ERR! Windows_NT 6.1.7601 ... and I had to turn off my Firewall and AntiVir

also this one here https://forums.tessel.io/t/error-using-npm-install-on-windows/212 there are a lot solutions for this problem what did you tried so far?

But it seems the directory that npm installs into is not on your path.

Did you try this stuff

When I did it on Windows, I then had to launch the 'node command shell' or whatever it's called. Basically, if you're on windows 8, and you search for 'node', you should see one item that is a command shell configured to run node. It has the standard 'cmd' looking black terminal icon.

Not to be confused with the 'node shell', which has the node.js logo. that one is an interactive REPL for node, which is NOT what you want to be in.

The command shell has the right path stuff already setup. If you just run a regular command shell, or PowerShell, the path won't be configured, unless you go into the system and configure it yourself.

Are you new to node or is this bug just happening in development? Maybe you should add your package json

This is how I solved the issue on Windows 8.1

• Go to your nodejs install (usually C:\Program Files\nodejs)
• Right click node_modules folder and go to properties
• Click the Security tab and advanced
• At the top you will see "Owner: SYSTEM". Click change.
• Enter the user you want permissions for and click ok
• Check the box at the bottom of the advanced settings "Replace all child object permission entries with inheritable permission entries from this object" and click ok
• Do whatever npm install/update you need
