请注意，minimal reproducible example as text 必须在问题本身中。不接受截图。 屏幕图片更不用说了。

【解决方案1】：

希望尝试下面的命令，它会被修复

ng update @angular/cli @angular/core

【讨论】：

我累了...但同样的问题@Dev216
尝试更新 --all --force
如果它不起作用，那么你运行下面的命令---- ng update @angular/cli @angular/core --force
npm i @angular/cdk@8 @angular/compiler-cli@8 @angular/material@8 rxjs@8 --save
@Owais 现在你的问题解决了吗？

【解决方案2】：

尝试添加force flag

ng update @angular/core --force

【解决方案3】：

您需要安装每个依赖项的兼容版本，这是该版本的代码

npm i --save dependencyName@version

【讨论】：

你能从上面的错误中发布一些例子吗...我是角度@Ess的新手
如果您已经安装了依赖项，请使用此ng update swimlane/ngx-charts@~8.2.12，否则以这种方式执行npm i swimlane/ngx-charts@^8.2.12 --save。如果您需要更多详细信息，请查看：checkMe
