node.js - 如何解决运行 npm install 时出现的 JSON 错误？

Question

当我在项目中运行 npm install 以安装依赖项时，出现 JSON 错误。

npm ERR! Unexpected end of JSON input while parsing near '...EsfB30RyD1HUtFKPTfwVO'

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/yogesh/.npm/_logs/2019-09-19T16_54_23_816Z-debug.log

我尝试清除缓存，但没有任何反应。

npm cache clean --force

还重新安装了nodejs和所有东西，但没有解决。

这是我的package.json

  "name": "project",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",

  },

    "@types/jasminewd2": "~2.0.3",

    "ts-node": "~7.0.0",
    "tslint": "~5.15.0",
    "typescript": "~3.5.3"
  }
}

如何解决这个问题？

Answer 1

只需卸载并重新安装 Angular cli。清除npm的缓存后

npm cache clean --force

npm uninstall @angular/cli
npm install @angular/cli

这将解决您的问题。
