有人能帮我解决这个问题吗?

Can anybody help me to resolve this?

推荐答案

我看到你在使用 webpack，我假设你在后端使用 google-cloud 库.

I see you're using webpack, and I'm assuming you're using the google-cloud library in the backend.

尝试将其放入您的 webpack 配置中:

Try putting this in your webpack config:

config = {
    // ...
    externals: {
        '@google-cloud/storage': 'commonjs @google-cloud/storage'
    },
    // ...
}

说明

用于后端的模块实际上并不是为了捆绑它们而制作的(请参阅:Webpack 后端应用).所以我们使用 webpack 的 externals 配置来排除不能很好地处理这种捆绑的库.当应用程序运行时，它们只是像平常一样从 node_modules 目录中require()'ed.

Explanation

Modules meant for the backend aren't really made with the intention of them being bundled (see: Backend Apps with Webpack). So we use webpack's externals config to exclude libraries that don't handle that bundling well. When the app is run, they are just require()'ed from the node_modules directory as normal.

如果您不想一一指定有问题的模块，请尝试使用 webpack-node-externals 自动排除所有模块.

If you don't want to specify your offending modules one-by-one, try out webpack-node-externals to automatically exclude all modules.
