Hello! When i run the npm install --legacy-peer-deps command it seems to try to install the npm packages defined in the package.json file. But it ends in a error and the error message includes the node-re2 package so im asking if you guys can help me. the error is below:

As far as I can tell you are trying to compile re2 on Node 20 and getting an error from node-gyp, which is a required dependency of any binary node extension:

npm ERR! gyp ERR! stack TypeError: Cannot assign to read only property 'cflags' of object '#<Object>'
npm ERR! gyp ERR! stack     at createConfigFile (C:\Users\janjy\OneDrive\Desktop\GiveAways API\node_modules\node-gyp\lib\configure.js:117:21)
npm ERR! gyp ERR! stack     at process.processTicksAndRejections (node:internal/process/task_queues:77:11)

It is likely node-gyp installed on that computer is too old and does not support Node 20:

npm ERR! gyp ERR! node -v v20.0.0
npm ERR! gyp ERR! node-gyp -v v7.1.2

The current version at the time of this writing is 9.3.1 (see https://www.npmjs.com/package/node-gyp).

Another possible concern can be the version of VS:

npm ERR! gyp info find VS using VS2019 (16.11.33529.622) found at:

My advice would be to update other related software when upgrading Node. Generally node-gyp should explicitly support a Node version because APIs and corresponding C++ headers change with every version.

So i tried to update my node-gyp to the latest version now, the error did not got fixed and the version of VS is the latest and i already tried to repair it with the "Repair Visual Studio" button.

What should i do now? Should i try to downgrade to nodejs v18?

I don't really know. Every time I commit a Github action builds the project on all supported platforms and run tests. To wit: https://github.com/uhop/node-re2/actions/runs/5082834983

You can inspect the command-line output of any job — they usually print out their exact configuration. You can see how it is different with your setup.

I got it. It was a issue with a npm package i had in my package.json. im still wondering why this Error happened now because im using this package since i think 1 year and i never had issues. I removed the package and after that it installed everything without any issue.
