类型错误：无法读取未定义的属性"tapPromise"

Question

我在Angular 9项目中使用Angular Build Optimization，并使用以下代码生成捆绑包，但出现以下错误。我用谷歌搜索了一下这个错误，但没有找到任何具体的答案。

正如错误所表明的那样，问题只出在图书馆本身。我也做了npm安装和npm审计修复，但一次又一次地得到同样的错误。

错误详细信息

我遇到了这个问题，但使用了React。原因是压缩插件版本和Webpack版本之间不兼容。

在你的情况下，我认为你使用Webpack"；间接地"；通过"@angular-builders/custom-webpack"，因为我在您的package.json中看不到

你的Webpack可能有以下来源吗？

"@angular-builders/custom-webpack": "^10.0.1"->"webpack-merge": "^4.2.2"->"webpack": "^5.3.2"

无论如何，"compression-webpack-plugin": "^7.0.0"需要"webpack": "^5.9.0"。因此，我建议您降级到"compression-webpack-plugin": "^6.0.5"，这取决于"webpack": "^5.3.2"。

试试那个版本或更低的版本，看看会发生什么。

信用

更新

这并不能改变我的结论：降级

一年多后，我发现自己再次检查Webpack的可能来源，显然我犯了一个错误，因为现在我发现"webpack-merge": "^4.2.2"依赖于"webpack": "^1.15.0"，而不是"webpack": "^5.3.2"。请注意，这是一个开发依赖项(devDependencies(。

我还发现了Webpack的另一个可能来源，这对我来说更有意义：
"@angular-devkit/build-angular": "^0.1100.3"->"webpack": "4.44.2"。注意，@angular-devkit/build-angular是@angular-builders/custom-webpack的依赖项。

此外，您分享的错误消息的第六行给了我们一个好主意，并证实了之前的假设：

(…(@angular builders\自定义webpack\node_modules\webpack\(…(

请注意，custom-webpack与webpack没有直接依赖关系。

现在，"compression-webpack-plugin": "^7.0.0"实际上具有以下依赖项：

peerDependencies: { "webpack": "^5.1.0"}
devDependencies: {"webpack": "^5.9.0"}

另一方面，"compression-webpack-plugin": "^6.0.5"实际上具有以下依赖关系：

peerDependencies: { "webpack":  "^4.0.0 || ^5.0.0"}
devDependencies: {"webpack": "^5.3.2"}

据我所知，compression-webpack-plugin是一个webpack插件，所以我认为在这个场景中重要的依赖是peer，它告诉我们支持的webpack版本。这可以解释"compression-webpack-plugin": "^6.0.5"工作的原因(对等依赖"webpack": "^4.0.0 || ^5.0.0"，通过build-angular: "^0.1100.3"可以获得"webpack": "4.44.2"(。

所有这些我都是通过复习许多"；package.json"；，安装软件包、阅读博客和使用NPMGraph(请参阅软件包的依赖关系图(
依赖关系比我想象的更复杂，所以我不排除某些方法是错误的，欢迎更正。

Answer 2

我在使用REACT进行开发时遇到了这个问题。我用过：

npm audit fix --force

它改变了两件事：

压缩webpack插件从^2.0.0到^8.0.1

webpack开发服务器从^3.11.0到^0.64.2

该命令破坏了我的开发系统，并按以下顺序抛出错误：

1. Error: Cannot find module 'webpack/bin/config-optimist'然后，我将webpack-dev服务器恢复到^3.11.0，并修改了错误
2. TypeError: Cannot read property 'tapPromise' of undefined然后我将压缩webpack插件恢复到^2.0.0

它解决了问题。
