generate stub doesn't work

[kevin-sakemaer]

When i launch this command :
protoc --dart_out=grpc:lib/src/generated -Iprotos protos/metadata.proto
i got the following error :

protoc-gen-dart: program not found or is not executable
--dart_out: protoc-gen-dart: Plugin failed with status code 1.

i have installed everything (protoc and the protoc_plugin)

The error indicates that you don't have protoc-gen-dart on your PATH. If you've installed it using pub global activate protoc_plugin, you'll also need to add ~/.pub-cache/bin to PATH.

Alternatively, you can point protoc at the plugin by adding --plugin=protoc-gen-dart=<full path to>/protoc-gen-dart to the protoc command line.

I can launch both from my terminal :/
Will try with the full path alternative

[jakobr-google]

What happens when you launch protoc-gen-dart directly? If everything works, it should "hang" (waiting for stdio input from protoc).

[kevin-sakemaer]

it's exactly what happend the program is waiting for input

[jakobr-google]

Then you've got me stumped. What version of protoc do you have?

[kevin-sakemaer]

libprotoc 3.4.0

[jakobr-google]

protoc 3.4.0 works for me, so that should be fine. Are there any spaces or other "weirdness" in the path to protoc-gen-dart? What OS are you running on?

If you can't get it to work using pub global activate, another alternative is to clone dart-lang/dart-protoc-plugin and use --plugin=protoc-gen-dart=<path/to/dart-protoc-plugin>/bin/protoc-gen-dart.

[kevin-sakemaer]

i have compile the source from the cpp release here https://github.com/google/protobuf/releases/tag/v3.4.0

[kevin-sakemaer]

no weird spaces or other in my path /home/kleak/.pub-cache/bin for protoc-gen-dart
I'm running on linux

[jakobr-google]

Pretty similar setup to mine. What does strace -f protoc --dart_out=... say? Does protoc look for protoc-gen-dart in the right place?

[kevin-sakemaer]

Ok i have found what is the problem
in my .profile i had and it doesn't work.

PATH="$PATH:~/.pub-cache/bin"

i have change to

PATH="$PATH:/home/kleak/.pub-cache/bin"

and it work now :)

[jakobr-google]

Ah, yes. Looks like protoc doesn't do ~ expansion, so we need the full path in PATH.

I'll close this one, then. Thanks for confirming!

[kevin-sakemaer]

yes problem solved :) thanks for the help

If you come across this, try replacing all mentions of ~ in your $path to /home/yourname. That fixed it for me.
