[lit-starter-ts] missing type definition for mocha

[majidsajadi]

Which package(s) are affected?

Starter Kits (@lit/lit-starter-js / @lit/lit-starter-ts)

Description

I tried to use lit-element-starter-ts to check out docs functionality but pnpm run docs throws a type error.

error TS2688: Cannot find type definition file for 'mocha'.
  The file is in the program because:
    Entry point of type library 'mocha' specified in compilerOptions

  tsconfig.json:30:15
    30     "types": ["mocha"]
                     ~~~~~~~
    File is entry point of type library specified here.


Found 1 error.

Reproduction

git clone https://github.com/lit/lit-element-starter-ts
cd lit-element-starter-ts
pnpm i
pnpm run docs

Workaround

pnpm i -D @types/mocha

Is this a regression?

No or unsure. This never worked, or I haven't tried before.
