grpc_tools_node_protoc in [email protected] fails with ENOENT

[josephharrington]

Problem description

When trying to run protoc from the [email protected] package on linux, it fails with "No such file or directory".

This also manifests as ENOENT when trying to run grpc_tools_node_protoc:

# ./node_modules/.bin/grpc_tools_node_protoc
/toolstest/node_modules/grpc-tools/bin/protoc.js:41
    throw error;
    ^

Error: spawn /toolstest/node_modules/grpc-tools/bin/protoc ENOENT
    at Process.ChildProcess._handle.onexit (internal/child_process.js:246:19)
    at onErrorNT (internal/child_process.js:427:16)
    at processTicksAndRejections (internal/process/next_tick.js:76:17)
    at process.runNextTicks [as _tickCallback] (internal/process/next_tick.js:51:3)
    at Function.Module.runMain (internal/modules/cjs/loader.js:804:11)
    at internal/main/run_main_module.js:21:11

From what I can tell, this is due to the protoc executable being a 32-bit binary in 1.7.0, whereas it was a 64-bit binary in 1.6.6:

$ npm install [email protected] && file node_modules/grpc-tools/bin/protoc
node_modules/grpc-tools/bin/protoc: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.18, BuildID[sha1]=1b2e70e2faad598dfc7849be2c4bd1e11190dde7, stripped

Reproduction steps

(run on macos via docker. similarly reproducible on linux.)

$ docker run --rm -it node /bin/bash
root:/# mkdir toolstest && cd toolstest/
root:/# npm install [email protected]
root:/# npx grpc_tools_node_protoc --version
spawn /toolstest/node_modules/grpc-tools/bin/protoc ENOENT

Environment

• OS name, version and architecture: Ubuntu 16.04.5 LTS(xenial), and also reproducible on the node docker image mentioned above
• Node version: 8.12.0 and 11.10.0
• Node installation method: nvm and node docker image
• Package name and version: [email protected]

Additional context

Here is the post that led me to believe this is related to the 64-bit/32-bit change: https://askubuntu.com/a/133460

Thank you for reporting this. It looks like there was an error in our build process. I think I have fixed it for 1.7.0. Would you mind trying it again?

[josephharrington]

Awesome, looks like it's fixed now. Thank you!!

[murgatroid99]

I'm going to keep this open for now. I haven't resolved the underlying build problem yet; I just uploaded a fixed tarball.

I have a similar issue for node:10-alpine docker image

Reproduction steps

$ docker run --rm -it node:10-alpine /bin/sh
/ # uname -a

/ # npm install [email protected]
/ # ./node_modules/.bin/grpc_tools_node_protoc
...
Error: spawn /node_modules/grpc-tools/bin/protoc ENOENT

Protoc is not able to execute too

@theanurin: this is a different issue altogether, and this package will likely never work on Alpine Linux.

[garenyondem]

@nicolasnoble Thanks! I was banging my head to the wall until I read your comment and switched to buster-slim. By the way, what is the problem with Alpine Linux?

[borfig]

The problem with Alpine images is the lack of a glibc compatability layer. So either you apk it or protoc directly.

[nathanweeks]

I encountered this issue with [email protected] on alpine:3.14, and apk add libc6-compat was enough to resolve it.

@nathanweeks It did solve it for me too, thanks! FTR: I'm working with docker image node:12.18.2-alpine3.12 and package [email protected]
