有人可以帮助我解决这个问题：我试图在laravel项目中执行npm运行生产（也使用webpack），并在位置132处获取SyntaxError：Unexpected token / in JSON（以及如何使用vscode捕获它们）尝试转换为JSON似乎有些错误，但我找不到它。谢谢您的帮助这是github repo

当WebPack尝试解析babel配置时，似乎出现了问题。从您提供的存储库URL中查看您的.babelrc，我发现

{

    "presets": [
        "@babel/preset-env", 
        "@babel/env",
        ["es2015", {"modules":false}]
    ]
}

// {
//     "presets": [
//     "@babel/preset-env",
//     "@babel/preset-react",
//     ["es2015", {"modules":false}]
//     ],
//     "plugins": [
//     "transform-class-properties",
//     "transform-object-rest-spread"
//     ]
//     }

Babel配置是一个JSON文件。该文件应仅包含有效的JSON对象。似乎您不知道JSON不支持注释。因此，您应该删除所有以“ //”开头的行。希望你的问题会消失。

如果您想了解有关JSON中注释的更多信息，请参见here的第二个答案
