使用 esbuild 的项目失败如下...

node_modules/htmlparser2/lib/Parser.js:133:36: error: Could not resolve "events" (set platform to "node" when building for node)
require("inherits")(Parser, require("events").EventEmitter);
                                    ~~~~~~~~

      text: 'Could not resolve "events" (set platform to "node" when building for node)'
    }
  ],
  warnings: []
}

...但是如果安装了包裹...

npm install --save-dev parcel-bundler

……它成功了。

测试是...

import '@virtualpatterns/mablung-source-map-support/install'
import _Bundler from 'esbuild'
import Path from 'path'

const { 'build': Bundle } = _Bundler
const FilePath = __filePath
const Require = __require

async function main() {

  try {

    await Bundle({
      'entryPoints': [ Require.resolve('../library/utility.js') ],
      'outfile': `process/esbuild${Path.extname(FilePath)}`,
      'minify': false,
      'bundle': true
    })
    
  } catch (error) {
    console.error(error)
  }

}

main()

...但我也尝试从命令行运行以下命令，但出现相同的错误（无堆栈跟踪）...

esbuild distributable-esmodule/library/utility.js --bundle --outdir=process/esbuild --sourcemap --platform=browser --log-level=info --strict
node_modules/htmlparser2/lib/Parser.js:133:36: error: Could not resolve "events" (set platform to "node" when building for node)
require("inherits")(Parser, require("events").EventEmitter);
                                    ~~~~~~~~
1 error

冒犯require("events")来自html-to-vdom. 我的utility.js 很小，包含以下导入的...

import _ConvertToVirtualNode from 'html-to-vdom'
import CreateVirtualNode from 'virtual-dom/h.js'
import VirtualNode from 'virtual-dom/vnode/vnode.js'
import VirtualText from 'virtual-dom/vnode/vtext.js'

我正在使用 esbuild v0.7.19。帮助。我还应该提供什么？

由于错误消息说set platform to "node" when building for node，我认为由于您没有这样做，这意味着您正在捆绑浏览器，而不是 node.js 。该events包内置于节点中，但未内置于浏览器中。

看起来parcel-bundler取决于取决于node-libs-browser哪个取决于crypto-browserify哪个取决于events。这解释了为什么安装 Parcel 会修复此错误。如果您的项目需要依赖events包 ( https://www.npmjs.com/package/events )，您应该自己安装它，使其成为您项目的一部分：

npm install events
