npm经常出现问题,一段时间后,在React项目文件夹中运行npm start
命令,该问题就会发生。
我得到几行日志,包括“无法解析json”和“ package.json必须是实际的JSON,而不仅仅是Javascript”。
在几周不使用后我开始处理该项目之后,问题总是会发生,我的package.json文件似乎很好,这是一个例子
{
"name": "carzyGame",
"version": "0.1.0",
"private": true,
"dependencies": {
"react": "^16.4.2",
"react-dom": "^16.4.2",
"react-scripts": "1.1.4",
"redux": "^4.0.0",
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject",
}
}
另一个:
{
"name": "neighborhood",
"version": "0.1.0",
"private": true,
"predeploy": "npm run build",
"deploy": "gh-pages -d build"
"dependencies": {
"escape-string-regexp": "^1.0.5",
"react": "^16.4.1",
"react-dom": "^16.4.1",
"react-foursquare": "^1.0.3",
"react-scripts": "1.1.4",
"sort-by": "^1.2.0"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
}
}
我尝试通过npm uninstall
卸载npm,但遇到了同样的错误,同样,删除节点模块文件也无济于事(目的是重新安装它)。
那该问题的原因是什么以及如何解决?
答案 0 :(得分:1)
错误的行是:
"redux": "^4.0.0",
"eject": "react-scripts eject",
与JavaScript不同,JSON对象的最后一个键值对中不允许使用逗号结尾。
