Failed to rebuild with node-gyp@6.1.0

[rilysh]

Trying to build a nodejs binding, whenever I run node-gyp rebuild it fails with Cannot assign to read only property 'cflags'. However, when I run node-gyp build I was successfully able to build it without any issues.

• Node Version: v19.6.0
• Platform: Linux tinyy 6.1.12_1 x86_64 GNU/Linux
• Compiler: gcc version 12.2.0 (GCC)

Verbose output (from npm or node-gyp):

I'm stuck on this error too. Very cryptic.
It started to happen when I upgraded to latest remix and then had to upgrade from Node 16 to 20.

❯ npm --version
9.8.1
❯ node --version
v20.6.1

Error is:

I can see the gyp info using node-gyp@7.1.0 but I don't have node-gyp installed explicitly. I don't know what package pulls it in.

Tried to follow the instructions, but no luck:

❯ npm install --global node-gyp@latest
npm config set node_gyp $(npm prefix -g)/lib/node_modules/node-gyp/bin/node-gyp.js

Newer versions of npm limit the number of config settings so node_gyp is not a valid npm option…

npm version
npm config list
npm config list -l
npm doctor

I switched to Node 18 and now it worked.
Running out of energy at the moment to go back in there and try again.

When I had Node 20 in my terminal, and in my GitHub action actions/setup-node, it would crash with TypeError: Cannot assign to read only property 'cflags' of object '#<Object>'.
But once I switched to Node 18 in my terminal (using nvm) and in my GitHub Action, now npm ci just works again.

Now I have:

❯ node --version
v18.17.1

❯ npm --version
9.6.7

Sorry @cclauss that I'm not trying those commands there right now. But hopefully this note left here, for someone else, can unblock them if they too tried to fly to close to the sun (i.e. using Node 20).

After hours of headache, downgrading to Node 18 just worked, thanks @peterbe

Adding dev dependencies
"node-gyp": "10.0.1", "nan": "2.18.0"
Also adding
"resolutions": { "nan": "2.18.0" }
to package.json worked for me for Node.JS 20 build failure
