Error when newest typescript is installed

[julianklose]

v2.0.1 doesn't work with the newest typescript version.
I saw that plugin has a dependency for typescript:^3.9. With this version everything works but when I update typescript to 4.3.5 I get this error:
--ts_out: TypeError: Cannot read property 'kind' of undefined

v1.0.13 didn't have any problems with typescript 4.

This installs fine for me:

npm init -y
npm i @protobuf-ts/plugin@2.0.1 typescript@4.3.5
curl https://raw.githubusercontent.com/timostamm/protobuf-ts/master/packages/test-fixtures/msg-readme.proto > msg-readme.proto
npx protoc --ts_out . -I . --experimental_allow_proto3_optional msg-readme.proto

node_modules/typescript will be 4.3.5.
node_modules/@protobuf-ts/plugin/node_modules/typescript will be 3.9.10.

Can you provide some details how you encountered this error?

I'm using yarn Plug'n'Play:

yarn set version berry
yarn init
yarn add @protobuf-ts/plugin@2.0.1 typescript@4.3.5
curl https://raw.githubusercontent.com/timostamm/protobuf-ts/master/packages/test-fixtures/msg-readme.proto > msg-readme.proto

add script to your package.json: 
"scripts": {"proto": "protoc --ts_out . -I . --experimental_allow_proto3_optional msg-readme.proto"},

yarn proto

The yarn pre-release version gets confused by @protobuf-ts/plugin's typescript peer dependency and updates it's non-peer dependency.

This will likely be fixed before yarn 2.0 is released, but we better drop the peer dependency until then.

Fix is released in @protobuf-ts/plugin@2.0.2. Thanks for the report! Please reopen if you notice something off.
