It says that this is a node-gyp bug. That's all I know. I don't know which directory it tries to access.

[rvagg]

That's not a happy error, it seems to be saying it can't read necessary files from your node install. You could try reinstalling Node.js (delete it first), or maybe npm install npm -g (upgrade npm in place which should reinstall these files) and see how that goes.

[KittyLe]

Upgrading npm did nothing, going to try reinstalling Node

[KittyLe]

Nothing changed, still this error.

[bzoz]

@KittyLe looks like you broken your Node installation, try reinstalling it. The robotjs doc says you need a compiler, make sure you have run npm install --global --production windows-build-tools from an elevated prompt as described in their doc.

If the problem persists, please provide verbose log by running npm i robotjs --verbose

[KittyLe]

@bzoz I already reinstalled it, rvagg said me to do that.
Also, there are logs.

[bzoz]

I see you have C:\Projects\caches\. That is something that is not standard. Could you share the result of env? Also, can you rerun the windows-build-tools installation with --verbose?

[KittyLe]

@bzoz, I don't know where to run env. Tried running it in npm and PowerShell.
This is the output of windows-build-tools --verbose

@KittyLe here's why that's an odd error and why we're saying your node install is "broken":

gyp ERR! command "C:\\Program Files\\nodejs\\node.exe" "C:\\Projects\\caches\\npm\\node_modules\\npm\\node_modules\\node-gyp\\bin\\node-gyp.js" "rebuild"

there's a package called "request" inside of node-gyp, which is inside of npm, that does simple HTTP requests to download headers tarballs for compiles. In that package, its index.js file is doing this on line 15: var cookies = require('./lib/cookies'), i.e. it's just loading a file of its own, located at C:\Projects\caches\npm\node_modules\npm\node_modules\request\lib\cookies.js. That's where the EPERM error is coming from, a standard Node require() call which simply loads a text file (that happens to contain JavaScript).

So, the user that's running npm i robotjs --verbose doesn't seem to have permission to read that particular file on your system.

Probably the most interesting thing here is _why_ it's doing anything in C:\Projects\caches and not C:\Program Files\nodejs\ where npm should actually be installed. Maybe the EPERM is more about the file not existing than not having permission. You may have some environment variable set that's redirecting it to a different location. Which is why you're being asked for an env. Run that in a cmd.exe window and paste the output here -- run your eye over it first to make sure there's nothing sensitive.

[KittyLe]

Which is why you're being asked for an env. Run that in a cmd.exe window and paste the output here

C:\Windows\system32>env

yeah.. env is not normally on a Windows box :)

And npm config list?

; node bin location = C:\Program Files\nodejs\node.exe

; "npm config ls -l" to show all defaults.

One thing I have noticed, windows-build-tools installed successfully on my laptop with Win8.1. And robotjs installed too and works fine.

@KittyLe it's the prefix that's causing problems. Run npm config delete prefix and it'll go back to using C:\Program Files\nodejs\node_modules (I think) as its global install location, which is where node-gyp should be located (inside npm).

[KittyLe]

Nothing changed.

ok, but now you have this unset, can you first try: npm install npm@latest -g to see if we can get npm properly reinstalled at that location. And second, if that still doesn't work, try uninstalling Node and reinstalling it again.

[hellojt9040]

Can you please continue. I am getting the same error. Please help.
