npm 在 windows 10 中运行构建

Question

This is the error I got when I execute the command in windows 10

 npm ERR! code EJSONPARSE
        npm ERR! file C:\Users\Dana\Desktop\Bootstrap_Coursera\Bootstrap4\conFusion\package.json
        npm ERR! JSON.parse Failed to parse json
        npm ERR! JSON.parse Unexpected token } in JSON at position 886 while parsing near '... npm 
        run usemin",
        npm ERR! JSON.parse   },
        npm ERR! JSON.parse   "author": "",
        npm ERR! JSON.parse  ...'
        npm ERR! JSON.parse Failed to parse package.json data.
        npm ERR! JSON.parse package.json must be actual JSON, not just JavaScript.

Answer 1

There's an excess comma after npm run usemin" (on the line with ... npm run usemin", ) in your package.json file. You have to remove this comma, since JSON does not allow trailing commas, causing a JSON parsing error.
