Description

Running yarn && yarn build works fine on macOS with node v14.15.0. Yet when I run the build inside the node:14-buster docker image, it fails.

Here's my repo. Running yarn && yarn build will work, but running docker build . fails with the error below.

Any suggestions on how I can debug this? Is there something different between macOS and debian in how ncc works? I'm at a loss as to how to investigate...

ncc: Version 0.25.1
ncc: Compiling file index.js
ncc: Using typescript@3.9.7 (local user-provided)

Research direction

Reproduce the difference by running yarn && yarn build and docker build . with the reported Node 14 environment. Inspect tsconfig.json and the build entry point index.js, then compare the TypeScript configuration and ncc behavior between macOS and node:14-buster. Done means the Docker build completes without TS18002.
