Question

我手动更新了package.json中的angular libraries和webpack。现在，当我运行应用程序时，我得到以下错误：

System.Exception: Call to Node module failed with error: WebpackOptionsValidationError: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
 - configuration.resolve.extensions[0] should not be empty.

Answer 1

你在resolve.extensions中使用了一个空字符串，这在webpack 2中不再允许或不需要。

而不是：

resolve: {
  extensions: ['', '.js', '.json']
}

你只需要：

resolve: {
  extensions: ['.js', '.json']
}

升级到webpack时，您需要修改其他重大更改2.阅读官方Migration Guide，了解您需要更改的内容。

在升级packaje.json条目时获取WebpackOptionsValidationError
