TypeError:无法读取未定义的属性“”tapPromise“”
TypeError:无法读取未定义的属性“”tapPromise“”
提问于 2020-12-05 18:49:39
我在Angular 9项目中使用了Angular Build Optimization，并使用了下面的代码来生成包，但得到了下面的错误。我在谷歌上搜索了这个错误，但没有找到任何具体的答案。
如错误所示，问题只存在于库本身。我也做了npm安装和npm审计修复，但一次又一次地得到相同的错误。

我也遇到过这个问题，不过是React。造成这个问题的原因是压缩插件版本和Webpack版本不兼容。
在你的例子中，我认为你通过"@angular-builders/custom-webpack"“间接”使用了Webpack，因为我在你的package.json中看不到它
你的Webpack有没有可能是这样的呢？
"@angular-builders/custom-webpack": "^10.0.1" -> "webpack-merge": "^4.2.2" -> "webpack": "^5.3.2"
不管怎样，"compression-webpack-plugin": "^7.0.0"需要"webpack": "^5.9.0"。所以我建议你降级到依赖于"webpack": "^5.3.2"的"compression-webpack-plugin": "^6.0.5"。
尝试这个版本或更低的版本，看看会发生什么。

我在使用REACT进行开发时遇到了这个问题。我使用：
npm audit fix --force它改变了两件事：
压缩-webpack-从^2.0.0到^8.0.1的插件
webpack-开发-服务器从^3.11.0到^0.64.2
该命令中断了我的开发系统，它按以下顺序抛出了错误：
然后，我将webpack-dev-
Error: Cannot find module 'webpack/bin/config-optimist'恢复到^3.11.0，错误是modified.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。
