repo

cause of the problem

microsoft/TypeScript#44710 adds the call of directoryExists method.

https://github.com/microsoft/TypeScript/blob/40fa0c9f118aa1ed2b06ae0b3eed3946d5d2c612/src/compiler/utilities.ts#L6593

This PR makes ts.parseJsonConfigFileContent return above error and empty fileNames array.

workaround

The workaround is just changing the tsconfig.json path to the absolute one.

- compiler_options: "./tsconfig.json",
+ compiler_options: path.resolve(__dirname, "./tsconfig.json"), // we cannot use <rootDir> here

resolution

I have no idea.

Is there anybody who has ideas for this issue?
