Question

我试图运行npm install而我得到了这个：

这是我的package.json文件：

}

任何帮助将不胜感激！

JSON似乎有效（我通过在线解析器运行它）。我在Windows下运行了相同的package.json并获得了以下输出：

所以，在预感中，我将您的devDependencies更改为dependencies，这样就有效了。所以我没有一个坚定的答案，但是你的文件中肯定存在npm存在问题 - 它只是一个JSON错误。

出于某种原因，我的package.json中存在错误的代码。不知道它是如何到达那里但我绝对没有把它放在那里。我重新安装了一切，它现在已经修复，正确的代码就在那里。

Package.json语法错误？
