betterproto v2.0.0b4

[Liu-Weijie]

When I used the command as follow:
protoc -I . --python_betterproto_out=lib e2sm_rc.proto
I got the error as follow:
--python_betterproto_out: protoc-gen-python_betterproto: Plugin failed with status code 1.
My version of the protobuf compiler is 3.15
I don't know where it goes wrong?

I can't tell from your issue, try using the latest version from GitHub.

[Liu-Weijie]

Ok, thanks, I found the version of the jinja2 is out of date, so I update it manually and it can work normally now

[chitalian]

I am also hitting the same issue! @Liu-Weijie Can you please elaborate what you mean by I found the version of the jinja2 is out of date, so I update it manually and it can work normally now?

I ran
pip install jinja2 -U and reran the command

python3 -m grpc_tools.protoc -I . --python_betterproto_out=. api.proto
--python_betterproto_out: protoc-gen-python_betterproto: Plugin failed with status code 1.

With the same error

@chitalian try importing jinja2 in some other script first. Don't know how, but it worked for me

[Liu-Weijie]

I am sorry that I just see the message.
you should pip uninstall jinja2 and pip install --upgrade jinja2
you can try it.

I tried importing jinja

I also tried pip uninstall jinja2 and pip install --upgrade jinja2 without any luck.

I even tried with pip install --upgrade --no-cache-dir jinja2 and this didnt work either

What does api.proto look like?

[chitalian]

@Gobot1234

syntax = "proto3";

package sisu.v1.api;

message AnalysesResultRequest {
  int64 limit = 1;
  int64 starting_after = 2;
  int64 csv = 3;
  int64 top_drivers = 4;
}

[chitalian]

I just tried in a brand new docker container and it failed the same way

[Gobot1234]

What does pip freeze look like?

[Gobot1234]

It looks to me like you didn't install "betterproto[compiler]", try pip install -U "betterproto[compiler]" --pre

[chitalian]

solved! Thank you!

[Gobot1234]

Seems like both of the issues here were fixed
