There is a problem when npm install

[IOAyman]

Make sure you have the C++ compiler installed on your system.

sudo apt install build-essential

[sammaina]

Also having issues with the installation on Windows (10). Installed G++ and still didn't work

npm: '3.10.8'

[IOAyman]

@sammaina In your case it's looking for the python executable (Line 2 of the error stack). Please add it to your %PATH% variable.

Linux-based OSes wont have issues concerning python because most of those OSes have it installed out of the box

[yangzgnay]

@IOAyman I have gcc installed. The same error is still here. I screen shot the whole message for your reference.

What possibly can it be? Thanks in advance.

[yangzgnay]

@sammaina You can follow the A.3 step of the following link to install python or add python to your PATH. Windows do not have python pre-installed. If you want to install python, please install python 2.7., since npm do not support 3.

Similar happens with macOS, It searches for XCode or CLT but fails and crashes.

I'm having the same issue in Ubuntu 16.04. I verified that I have C++ compiler and Python 2.7.1 installed and in path. Had Node 4, tried updating to 6.9.1, still didn't work. NPM 3.10.9.

This is my stack running npm install (directory = [...]):

@IOAyman @yangzgnay Thanks it helped. Landed into the same error.
Error: gyp failed with exit code: 1

[jotaporras]

Guys, it seems it's a bug with the robotjs dependency. I updated line 23 of package.json to
"robotjs": "^0.4.5",

and now npm install works.

[yangzgnay]

@jotaporras
Still not work on my side after changing ^0.3.7 to ^0.4.5. The same error appears.

[jotaporras]

@yangzgnay Maybe take a look at octalmage/robotjs#17 ?
The people there speak about a couple of other dependencies that might be needed. Also consider switching to node 6

[mercuryw]

I have problem when npm install. I think it has something to do with Robotjs package.
I have Visual Studio, python2.7.

Can someone help me? Thanks.

[EduardoHillebrand]

Idk but i guess it only works on mac OS.

[HusainZafar]

@jotaporras Works for me. Thanks
