我对我的无服务器项目有一个问题。

这是我的webpack配置：

代码语言：javascript
复制
// webpack.config.js
const path = require('path');
const webpack = require('webpack');

module.exports = {
  target: 'node',
  plugins: [
    new webpack.IgnorePlugin({ resourceRegExp: /^pg-native$/})
  ],
  module: {
    rules: [
      {
        loader: 'ts-loader',
        options: {
        transpileOnly: true
        },
      }
    ]
  },
  resolve: {
    extensions: ['.ts', '.js', '.tsx', '.jsx']
  },
  output: {
    libraryTarget: 'commonjs',
    path: path.join(__dirname, '.webpack'),
    filename: 'handler.js'
  },
  mode: 'development'
};

和我的serverless.yml：

代码语言：javascript
复制
provider:
  name: aws
  region: "eu-west-1"
  stage: dev
  timeout: 10

custom:
  webpack:
    webpackConfig: webpack.config.js
    includeModules: false # this is telling webpack to reference all dependencies (non-dev dependencies) in node_modules and serverless would upload the package.json with the node_modules folder
    # forceExclude:
    #    - pg-native
package:
    individually: true

plugins:
  - serverless-webpack
  - serverless-plugin-typescript
  - serverless-offline

和package.json：

代码语言：javascript
复制
"dependencies": {
    "@babel/types": "^7.12.12",
    "@types/aws-lambda": "^8.10.61",
    "@types/bcrypt": "^3.0.0",

    "typescript": "^3.9.7"
  },
  "devDependencies": {
    "@babel/core": "^7.12.9",
    "@babel/preset-env": "^7.12.7",
    "@types/jest": "^26.0.16",
    "babel-jest": "^26.6.3",
    "copy-webpack-plugin": "^7.0.0",
    "jest": "^26.6.3",
    "serverless-webpack": "^5.3.5",
    "ts-jest": "^26.4.4",
    "ts-loader": "^8.0.12",
    "webpack": "^5.11.0",
    "webpack-node-externals": "^2.5.2"
  }

我无法删除的错误是：

     Components Version:        3.4.2

这里有人有什么建议吗？我尝试添加别名，尝试使用排除包(就像当前在webpack.config中一样)，但都无济于事。

关于pg-native是C++的问题的评论忽略了关键点：pg模块在浏览器和节点上都可以工作，但Webpack感到困惑，并试图打包本机模块。

简单的解决方案是在Webpack配置中排除pg-native。这很好用。

一个陷阱是，当我把Webpack从4升级到5的时候，我之前的工作设置坏了。

以下是对我有效的方法：

Webpack 5：

代码语言：javascript
复制
new webpack.IgnorePlugin({ resourceRegExp: /^pg-native$/}),

Webpack 4：

代码语言：javascript
复制
new webpack.IgnorePlugin(/^pg-native$/),
