Why can’t you find the problem of package.json with npm

  node.js, question

Recently, I started playing node and installed it normally with bower. However, when reading the online tutorials and installing things step by step, I always report an error, which may not have been set up before. If it is troublesome to set up now, is there any good way to delete all the previous ones and reinstall them normally?图片描述
