We are using the expo-cli as a local dependency to run web:build from a npm script without global installation of expo-cli. When executing npm run build:web we get the exception below.
To create a minimal example we created a blank typescript project with expo init and ran npm install -D expo-cli. Doing the same without typescript everything worked as expected, so we think that the problem has something to do with typescript.
