Cannot find module 'pulsar-client@1.12.0' by pnpm

[JeffHu88]

I tried to migrate an old project from NPM to PNPM, but after running pnpm install, when I try to start the project, I encounter a MODULE_NOT_FOUND error. How can I fix this issue?

node:internal/modules/cjs/loader:1247
  throw err;

Cannot find module 'pulsar-client@1.12.0' by pnpm

I came across the same issue. When using pnpm the bindings don't get built automatically.
You can fix this problem with the following workaround:

1. Uninstall the pulsar-client
   pnpm uninstall pulsar-client

2. Add the following post install script to your top level package.json of your pnpm workspace. Replace 1.12.0 with the pulsar-client with the version you are using.

  "scripts": {
    "postinstall": "cd ./node_modules/.pnpm/pulsar-client@1.12.0/node_modules/pulsar-client && pnpm run install"
  },

3. Install the pulsar-client with the version matching in your package.json
   pnpm install pulsar-client@1.12.0

Running into the same issue, and this fix worked thanks!

Any idea on the root cause of this? Does this logic need to move into postinstall step instead directly in pulsar-client?

The workaround seems does not work with node 22.x in MacOS.

Expected in: /usr/lib/libc++.1.dylib █ ┃ in /private/var/www/github/proj/node_modules/.pnpm/pulsar-client@1.16.0/node_modules/pulsar-cl █ ┃ ient/lib/binding/pulsar.node

I think the root cause: The native binary was compiled against an older C++ ABI / Node / V8 version, and Node 22 cannot load it

Which means Pulsar can not use with node 22 and above?
