作业名称"..getProjectMetadata"不存在 [英] Job name "..getProjectMetadata" does not exist

问题描述

我将我的角度更新为v9，当我尝试在v8中返回时，收到此错误. 我已经尝试了以下方法:

I updated my angular to v9 and when I try to go back in v8, I receive this error. I have already tried the following:

• 卸载-global angular/cli
• 卸载angular/cli
• 回到我的上一个package.json
• 删除node_module文件夹
• 删除存储库

此错误继续显示.

我的堆栈跟踪是:

An unhandled exception occurred: Job name "..getProjectMetadata" does not exist.
See angular-errors.log for further details.

推荐答案

@angular-devkit/build-angular似乎是一个问题. 尝试将其降级为特定版本:

It seems to be an issue with @angular-devkit/build-angular.. Try downgrading it to a specific version:

npm i @angular-devkit/build-angular@0.803.24
