I encountered the same issue upgrading to version 3.21.1 from 3.20.0

Would love to help in any way if I can :)

I'm having the same issue on macOS:

protoc-gen-js: program not found or is not executable
Please specify a program using absolute path or make sure the program is available in your PATH system variable
--js_out: protoc-gen-js: Plugin failed with status code 1.

I don't see protoc-gen-js in any of the binary downloads; couldn't figure out whether or not there is a separate install for this or if it should be "included" in the protoc binary as before.

I've seen that the release notes for v21.0-rc1 link to a document explaining that javascript has been moved out of the main repository to allow it to evolve independently of protoc. However, the new protobuf-javascript repository does not provide any instructions that helps me resolve this issue.

Note that the v20.1 release provides an additional js asset that I also wasn't able to make use of. Couldn't find any useful instructions.

I downgraded to v20.1 and then I don't get this problem.

PS: I'm new to installing protobuf from the official releases; I've used brew in the past, but it seems the homebrew folks are having some problems with v20.1 as well, with v3.19.4 being the most recent working version.

@haberman 21.x breaks JS and there's no known workaround for OSX / brew
Can you take a look and provide some guidance, please

no release notes on removing JS

no way to downgrade

brew install protobuf@20.1
==> Auto-updated Homebrew!
Updated 1 tap (homebrew/core).

Running `brew update --auto-update`...
Warning: No available formula with the name "protobuf@20.1". Did you mean protobuf@3.6?

 brew install protobuf@3.6
Error: protobuf@3.6 has been disabled because it is a versioned formula!

no releases on the js split

https://github.com/protocolbuffers/protobuf-javascript

no build instructions on the js split

https://github.com/protocolbuffers/protobuf-javascript

the latest known working js release has no build instructions either

protobuf-js-3.20.1.tar.gz

[clehene]

workaround on OSX / brew:

brew install protobuf@3
brew link --overwrite protobuf@3

Installed protobuf 21.4 with homebrew, which uses protoc 3.21.4, and also got the same protoc-gen-js: program not found or is not executable error.

The suggestion by @clehene worked like a charm
