Can't setup protoc-gen-firebase_rules (Missing input file)

[nilsreichardt]

I try to set up this library. Unfortunately I have problems with step no. 3:

3. Either put the plugin binary on your $PATH or use the --plugin=protoc-gen-firebase_rules=./path/to/protoc-gen-firebase_rules option

If I do this, I get this error message: Missing input file.

What I tried:

• protoc --plugin=protoc-gen-firebase_rules
• protoc --plugin=protoc-gen-firebase_rules=/Users/nils/Desktop/SDKs/protoc-gen-firebase_rules
• protoc --plugin=protoc-gen-firebase_rules=./protoc-gen-firebase_rules
• protoc --plugin=protoc-gen-firebase_rules=protoc-gen-firebase_rules

Additional information:

• I already added protoc-gen-firebase_rules to my $PATH (export PATH=/Users/nils/Desktop/SDKs:$PATH)
• protoc --version: libprotoc 3.13.0
• MacOS: 10.15.5

@AndroidNils you're missing one more argument: the proto files you want to compile.

I did this and got your error:

$ protoc --plugin=~/Downloads/protoc-gen-firebase_rules --firebase_rules_out=./gen
Missing input file.

And then I pointed to the .proto file and it worked:

$ protoc --plugin=$HOME/Downloads/protoc-gen-firebase_rules --firebase_rules_out=./gen rules.proto
