生成（Webpack）时出现TypeORM'找不到模块'

标签： typescript webpack node-gyp typeorm

我用一段时间搜索了这个问题，并在typeorm github上找到了几篇文章，但是由于没有提供解决方案，它们都被关闭了。这似乎是一个webpack问题，但我不知道问题到底是什么。该示例对我来说编译很好。

一旦我调用createConnection导入的typeorm，就会发生这种情况。我得到的错误如下。我删掉了大多数“无法解决...”的问题，但您明白了。

我的package.json（我删除了一些依赖项以将其缩短一点）

const path = require('path')

const commonConfig = {
  output: {

    filename: '[name].js'

          }
        ]
      }
    ]
  },
  node: {
    __dirname: false,
    __filename: false
  },
  resolve: {
    extensions: ['.js', '.ts', '.tsx', '.jsx', '.json']
  }
}

module.exports = [
  Object.assign(
    {
      target: 'electron-main',
      entry: { main: './src/main.ts' }
    },
    commonConfig),

  Object.assign(
    {
      target: 'electron-renderer',
      entry: { gui: './src/gui.tsx' },
      plugins: [new HTMLWebpackPlugin({
        title: 'something',
        template: './src/index.html'
      })]
    },
    commonConfig)
]

感谢您的帮助！

在设置项目时遇到了同样的问题。

要解决此问题，您可以将以下插件添加到您的webpack配置中，以删除有关您不想使用的插件的警告

new FilterWarningsPlugin({
    exclude: [/mongodb/, /mssql/, /mysql/, /mysql2/, /oracledb/, /redis/, /sqlite3/, /sql.js/, /react-native-sqlite-storage/]
})

希望对您有帮助：）
