Почему node.js устанавливает две папки node_modules?

Всякий раз, когда я пытаюсь запустить npm install или npm start, я получаю эту ошибку:

bash: line 0: cd: packages/react-scripts: No such file or directory
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] start: `cd packages/react-scripts && node bin/react-scripts.js start`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the [email protected] start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR!     C:\Users\Aristophanes\AppData\Roaming\npm-cache\_logs\2018-11-09T12_14_19_704Z-debug.log

Понятия не имею, почему я начал это получать. Кто-нибудь может пролить свет? Я пробовал удалить и снова установить, но это не помогает. Кроме того, я не знаю почему, но node.js устанавливает 2 папки node_modules на моем компьютере - одну в моем каталоге C://Program Files/nodejs/, а другую в C://Users/Aristophanes/. Два файла package.json в каждом разные.
