protobuf have issue with typescript long : Cannot find name 'Long'

[chloe2018s]

I'm new to protobuf. I'm using "protobufjs": "^6.8.8" for generating typescript. And imported this generated file to my component.spec.ts , then got compilation error when run ng serve
[ERROR] target/generated-sources-js/xxx.d.ts(4253,40): error TS2304: Cannot find name 'Long'.

I included the "@types/long": "^4.0.0", "long": "^4.0.0", in my package.json dependencies. Still got the same error.

Please advise. Many thanks

You need to add the following configuration

{ "compilerOptions": { ... "types": [ ..., "Long"] } ... }

in the tsconfig.jsonfile

compilerOptions.types add "Long" to array

Greetings! I think we fixed this over in #1166

Is there a plan to release a new version anytime soon? This bug exists in 6.8.8, and the fix was never released.

i fixed Cannot find name 'Long' problem in my angular project.

solution steps:

1. add "@types/long": "^4.0.0", "long": "^4.0.0", in my package.json dependencies
2. add configuration { "compilerOptions": { ... "types": [ ..., "Long"] } ... } in my tsconfig.app.json.
