2.0.1 throwing error on install

[sachaw]

Using TS 4.3.5, upgrading from 2.0.0 to 2.0.1 throws:

An unexpected error occurred: "could not find a copy of typescript to link in ~/node_modules/@protobuf-ts/plugin/node_modules".

This is a bug in yarn 1.x, see yarnpkg/yarn#6285 (comment).

The following works without error in yarn 1.22.10:

yarn init -y && yarn add typescript@4.3.5 && yarn add @protobuf-ts/plugin

Did you find a workaround?

No workaround ATM, I may be switching to pnpm though.
As I wish to use the latest TS version, I will leave the package at 2.0.0 for now,
Thanks.

Thank you. Since yarn init -y && yarn add typescript@4.3.5 && yarn add @protobuf-ts/plugin does install, I presume the error only manifests when a node_modules directory is present. I recommend deleting that directory before updating, or - in case that should be insufficient - deleting the lock file as well.
