Node_01_ Custom Module (create Package.json first)

Package.json must be in JSON format

You must make sure that all strings, including property names , are used in  double quotes instead of single quotes

{"Name": "163", "Version": "1.0.0", "description": "A vue.js Project", "private": True, "dependencies": {"exp Ress ":" ^4.16.2 "," Vue ":" ^2.5.2 "," Vue-router ":" ^3.0.1 "}, view all the properties of the Package.json file document, you can use the following command:

$ NPM Help JSON

Tip: If you do not want to publish your module, add "private" to Package.json: "true". This avoids mis-publishing.
