Cannot find module '/Users/JounQin/.dts/typescript-installs/next/node_modules/typescript'

I tried deleting yarn.lock and install all dependencies like https://github.com/microsoft/dtslint#faq but it didn't work.

Error: Command failed: yarn dtslint --expectOnly packages/svelte

Could this have been due to concurrent dtslint invocations trampling each other installing TypeScript versions? https://github.com/rx-ts/types/blob/544b5fdcb44a2c6c63ba9391752bef8affad4711/scripts/dtslint.ts#L15

I realize this comes a bit late: that dtslint.ts script has been removed. I just ran into a similar issue with lerna run that I (think) I solved with lerna --concurrency 1 run.
