Question

I'm getting the following error while doing npm install:

I'm not completely sure what is breaking the install, if fibers or somehow that python SyntaxError: invalid syntax However, trying to install fibers individually throws same error. npm i -g fibers doesn't fix, neither changing npm configure set python /path/to/python. Deleting fibers momentarily keeps throwing same Python SyntaxError: invalid syntax error, this time with another node_module.

This is the solution to this issue.

Explanation:

Notice this part of your NPM error log:

npm ERR! gyp ERR! node-gyp -v v3.8.0

This means your code is trying to install node-gyp of the version 3.8.0

What is probably happening (this was in my case) you have a wrong NodeJS version, for node-gyp.

I searched for the right version of NodeJS for node-gyp 3.8.0, and the answer is below.

Solution:

Uninstall current NodeJS version
Install NodeJS Version 6.17.1 (if you need multiple NodeJS versions use NVM tool (Instructions For Windows/Linux/MacOS) https://www.nubo.eu/Install-Multiple-Node-Versions-On-Windows/
Run npm install in your project again

Downgrading indeed solved the problem, in my case I've used Node version manager as this [comment](https://stackoverflow.com/a/7718438/13784272) – Jesus Jimenez Jun 22 '21 at 00:53
In my case I downgraded to Node 14.17.6 (npm 6.14.15) – Alex Pappas Jan 02 '23 at 17:15

I got this error when I set a PATH variable incorrectly which meant npm and node couldn't be found correctly.

To diagnose this, I ran

npm --version
node --version

It said command not found, so I checked env | grep PATH which showed me that the location of npm and node weren't on PATH as they needed to be. Once I fixed that, everything worked as expected.

I got the same/similar issue without making any changes to version of node. I hate to be that guy, but after a day of struggling with it I decided to restart my machine. That fixed it...

The issue is that node-gyp tries to build with Python 2 syntax: print "%s.%s.%s" % sys.version_info[:3]; which throws an error probably because you have Python 3 on your computer.

This usually occurs when installing an outdated npm module which is not compatible with the current Node version on your system. Try installing Python 2 and set it to the path, or locate the offending module in package.json and then upgrade the version number to the one that is compatible with your current Node version.
