webpack 5错误“不能解决'uglify-js'，'@swc/core'，'esbuild‘

Question

我有一些错误的webpack 5，表示，github的行动。我使用github操作是因为想要使用github秘密。另外，我使用webpack是因为使用代码中的秘密。

总之，我在下面有错误，

ERROR in ./node_modules/terser-webpack-plugin/dist/utils.js 479:6-26
Module not found: Error: Can't resolve 'uglify-js' in '/Users/luna/workspace/express_api/node_modules/terser-webpack-plugin/dist'

还有15次警告。如果你想听警告，告诉我。

有什么问题吗？

下面是webpack.config.js

const webpack = require("webpack");

module.exports = {
  target: "async-node",
  mode: "production",
  entry: "./app.js",
  output: {
    path: "/dist",
    filename: "main.js",
  },
  plugins: [
    new webpack.DefinePlugin({
      "process.env.PA_URL": JSON.stringify(process.env.PA_URL),
      "process.env.PA5_EMAIL": JSON.stringify(process.env.PA5_EMAIL),
      "process.env.PA5_PASSWORD": JSON.stringify(process.env.PA5_PASSWORD),
    }),
  ],
};

webpack版本是错的吗？

Answer 1

您正在捆绑您的输入文件，但也绑定了您的./app.js所需的任何./app.js，这反过来又试图要求一堆第三方的东西，这些东西是不可用的，因此出现了丢失模块上的错误。

通过扩展webpack配置：node_modules (参见：https://www.npmjs.com/package/webpack-node-externals)，排除那些

const webpack = require("webpack");
const nodeExternals = require("webpack-node-externals");

module.exports = {
  target: "async-node",
  mode: "production",
  entry: "./app.js",
  externalsPresets: { node: true },   // <-- here
  externals: [nodeExternals()],       // <-- and here
  ...etc

这应该把他们排除在外，你应该做得很好。
