json - NPM 命令返回错误：package.json 必须是实际的 JSON，而不仅仅是 JavaScript

问题描述

...而且我知道我的 json 是完全有效的 json。当我向 package.json 添加一些开发依赖项时，问题就开始了，但它似乎在第一行就被绊倒了。我已经验证并清理了缓存，更新了 npm，并且我已经梳理了一段时间的文件和有关此问题的帖子，但无法弄清楚发生了什么。我还尝试了一些我在这里看到的建议，比如将所有 " 字符更改为 ' 字符。Nada。

我的 package.json 如下，以及运行命令时的完整错误消息：

任何帮助将不胜感激！

PS 我在 Windows 10 上运行 Gitbash，但我试图确保没有特定于 Windows 的字符。也许我错了。

解决方案

问题可能比你忽略的更简单？

我在网上看到（近乎依赖）你缺少一个逗号：

    "webpack-dev-server": "^3.11.0"
    "yo": "^3.1.1"

建议你加个逗号，然后再运行npm install试试？

    "webpack-dev-server": "^3.11.0",
    "yo": "^3.1.1"
