Custom { kind: PermissionDenied, error: "failed to invoke protoc (hint: https://docs.rs/prost-build/#sourcing-protoc): (path: \"F:\\\\.protoc\\\\bin\"): 拒绝 访问。 (os error 5)" }' #44

Running https://docs.rs/prost-build/latest/prost_build/ under win10 system prompts Custom { kind: PermissionDenied, error: "failed to invoke protoc (hint: https://docs.rs/prost-build/#sourcing-protoc): (path: "F: \\.protoc\\bin"): Denied access. (os error 5)" }', you are already a super administrator, but you will still be prompted with an error similar to insufficient permissions

It has been troubled for several days, I hope someone can help me to solve it

Can you invoke protoc by itself?

Can you invoke protoc by itself?

Yes, it is possible to call protoc directly from the command line.

same error

I am not sure then, I would need to find a way to reproduce this. One option is to start using protox as it is a pure rust implementation and wouldn't require you to have protoc available.

same error, any solution about that?

I encountered a similiar error. I'm running with GitHub Actions.

Project: https://github.com/DiscreteTom/shremdup

I use the following command to put protoc in PATH:

wget https://github.com/protocolbuffers/protobuf/releases/download/v3.20.3/protoc-3.20.3-linux-x86_64.zip
unzip protoc-3.20.3-linux-x86_64.zip -d protoc3
mv protoc3/bin/* /usr/local/bin/

Got the following error:

Error: Custom { kind: NotFound, error: "failed to invoke protoc (hint: https://docs.rs/prost-build/#sourcing-protoc): (path: \"/usr/local/bin/protoc\"): No such file or directory (os error 2)" }

My issue is fixed by using a newer version of protoc: 23.2

Hi, I have the same error on Windows 11 and WSL2 (Ubuntu 22) with protoc 23.4 and 24.2

W11 Error: Custom { kind: PermissionDenied, error: "failed to invoke protoc (hint: https://docs.rs/prost-build/#sourcing-protoc): (path: \"W:\\\\protoc\\\\bin\"): Access is denied. (os error 5)" }

WSL2 Error: Custom { kind: PermissionDenied, error: "failed to invoke protoc (hint: https://docs.rs/prost-build/#sourcing-protoc): (path: \"/root/protoc/bin\"): Permission denied (os error 13)" }

Any progress here? Was anyone able to handle this error? I am facing this on windows with protoc 24.2

The environment variable must point to the exe file
