Build script using pbjs fails when called with bun, but not npm. Works when build script uses npm, but called with bun run.

[losh11]

What version of Bun is running?

1.0.31+e25675121

What platform is your computer?

Darwin 23.2.0 x86_64 i386

What steps can reproduce the bug?

My library has a build command which previously worked when doing npm run build. This build command runs another command calls bun run protobuf, this command in return runs another commands which uses pbjs to generate js from a .proto file.

package.json

"build": "rm -rf dist && mkdir dist/ && bun run protobuf && bun tsc -p ./src",
"protobuf": "bun run protobuf:rpc & ...",
"protobuf:rpc": "mkdir -p dist/protos && pbjs -t static-module -w commonjs -o dist/protos/rpc.js src/protos/rpc.proto && pbjs -t static-module src/protos/rpc.proto | pbts -o dist/protos/rpc.d.ts - && cp dist/protos/rpc.* ./src/protos/",

What is the expected behavior?

Changing from npm -> bun in the build scripts fails to run with error below. However previously when build scripts use npm, running bun run build worked as expected.

What do you see instead?

$ bun run build
$ rm -rf dist && mkdir dist/ && bun run protobuf && bun tsc -p ./src
$ bun run protobuf:rpc && bun run protobuf:walletunlocker && bun run protobuf:stateservice && bun run protobuf:wtclient
$ mkdir -p dist/protos && pbjs -t static-module -w commonjs -o dist/protos/rpc.js src/protos/rpc.proto && pbjs -t static-module src/protos/rpc.proto | pbts -o dist/protos/rpc.d.ts - && cp dist/protos/rpc.* ./src/protos/

Additional information

Weirdly, running the bun run build script after it first errors, seems to work as expected.

Based on the output of the command, even though you are running bun run, the script is using node. What if you try bun --bun run build?

No error if I omit the --bun flag.

Thank you!

https://github.com/carrismetropolitana/discord-bot Can reproduce here. Had to add a node install to my Dockerfile to actually bundle stuff properly.

Try to run bun run --bun gen.
