require addon reports `ELF SyntaxError: Invalid or unexpected token` #46856

Closed Zvicii closed 1 year ago

Zvicii commented 1 year ago

Version

v16.19.1 & v18.14.2

Platform

Linux e0b3b5af329d 5.10.16.3-microsoft-standard-WSL2 #1 SMP Fri Apr 2 22:23:49 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Subsystem

No response

What steps will reproduce the bug?

I wrote a node addon using node-api, it works fine on Windows and macOS, but on Linux, it reports SyntaxError. After browsing though the community and the internet, I found people who are getting the same error.

https://github.com/vercel/pkg/discussions/1643 https://github.com/Unitech/pm2/issues/4775

How often does it reproduce? Is there a required condition?

Stable recurrence

I'm testing using ubuntu 1604 with node 16.19.1 and ubuntu 2204 with nodejs 18.14.2. Getting the same error.

What is the expected behavior?

nodejs loads node-nim.node and treat it as a node addon

What do you see instead?

Can you show the contents of test.js?

Zvicii commented 1 year ago 
const test = require('/home/conan/nim-cross-platform-sdk/build/lib/node-nim.node')
console.log('test')
mscdex commented 1 year ago

Your error output shows this filename being loaded:

/home/conan/nim-cross-platform-sdk/build/lib/node-nim.node.9.9.2

instead of

/home/conan/nim-cross-platform-sdk/build/lib/node-nim.node

Perhaps that is the cause? Is the latter a symlink to the former or is your code being transformed somehow to require the former?

Zvicii commented 1 year ago

Sorry I didn't make myself clear，node-nim.node is just a symlink to node-nim.node.9.9.2. change test.js to 

const test = require('/home/conan/nim-cross-platform-sdk/build/lib/node-nim.node.9.9.2')
console.log('test')

has the same output

mscdex commented 1 year ago

I believe you need a .node at the end of the filename for node to treat it as an addon.

Zvicii commented 1 year ago

I believe you need a .node at the end of the filename for node to treat it as an addon.

yes! thats it, so Im actually requiring node-nim.node.9.9.2 which is not ended by .node. After changing it to node-nim.node and remove the symlink, its working now, Many thanks!
