问题 I noticed this strange behavior which is not a big deal, but bugging the heck out of me. In my package.json file, under the "scripts" section, I have a "start" entry. It looks like this: "scripts": { "start": "APPLICATION_ENV=development nodemon app.js" } typing npm start on a Mac terminal works fine, and nodemon runs the app with the correct APPLICATION_ENV variable as expected.

问题 I have a core library with the following in package.json : "main": "dist/cjs/index.js", "module": "dist/esm/index.js", "es2015": "dist/es2015/index.js", "types": "dist/es2015/index.d.ts", "typings": "dist/es2015/index.d.ts", The library builds TypeScript code into dist/ folder for distribution.
