工作名称“ . . getProjectMetadata”不存在

我将角度更新到 v9，当我试图回到 v8时，我收到了这个错误。 我已经试过以下方法:

  • 卸载-全局角度/cli
  • 卸载 angle/cli
  • 回到我最后一个包裹 Json
  • 删除节点 _ 模块文件夹
  • 删除回购

继续显示此错误。

我的堆栈痕迹是:

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

角度误差日志:

最佳答案

这似乎是一个问题，与 @angular-devkit/build-angular. 。 试着把它降级到一个特定的版本:

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

正如 Occian Fumnanya Dia 在他上面的回答中所说的那样，我也遇到了同样的问题，并且通过将 @angular-devkit/build-angular.版本降级到 0.803.24来解决了这个问题 如果在降级版本之后仍然得到相同的错误，尝试删除文件夹 platforms并用 ionic cordova run <platform>重新运行。用 android或 ios代替 <platform>。

它将使用新内容重新创建文件夹 plaforms。

希望能有帮助。

不要删除整个 node _ module 文件夹，只要重命名它并尝试

npm install
sudo npm install --unsafe-perm //for macOS

请在下面找到我的角包的版本-

"@angular-devkit/build-angular": "0.802.0",
"@angular-devkit/core": "8.2.0",
"@angular/animations": "8.2.0",
"@angular/cli": "8.2.0",
"@angular/common": "8.2.0",
"@angular/compiler": "8.2.0",
"@angular/compiler-cli": "8.2.0",
"@angular/core": "8.2.0",

这个命令暂时修正了这种情况:

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

我的 Jenkins 版本要求我运行 Npm 审计修复程序命令来下载 Dependencyes。此命令使同一错误再次出现。 有人知道怎么让审计指令忽略 Angula-devkit 吗？

也运行 npm i @angular-builders/custom-webpack@8.4.1 --save

对我来说，Occian 的回答是不够的，我还必须改变 @angular-builders/custom-webpack从 latest到 8.4.1，因为它有 build-angular的依赖。下面是如何解决这个问题的方法:

Npm list@angle-devkit/build-angle

reports-web-client@0.0.0 C:\projects\2778\reports-web-client
+-- @angular-builders/custom-webpack@9.1.0
| `-- @angular-devkit/build-angular@0.901.1
`-- @angular-devkit/build-angular@0.803.8

这意味着，我有两个版本的软件包，这就是为什么错误仍然会出现。

如果您使用 npm 审计修复程序，找到您试图修复的包，并将其恢复到稳定版本，并注意漏洞。

根据我的经验，您使用的新模块是为 angular9设计的，您应该升级您的导入，如果可能的话:

 "dependencies": {
"@angular/animations": "^9.1.9",
"@angular/cdk": "^9.2.4",
"@angular/common": "^9.1.9",
"@angular/compiler": "^9.1.9",
"@angular/core": "^9.1.9",
"@angular/forms": "^9.1.9",
"@angular/platform-browser": "^9.1.9",
"@angular/platform-browser-dynamic": "^9.1.9",
"@angular/router": "^9.1.9",
...
}
"devDependencies": {
"@angular-devkit/build-angular": "^0.901.7",
"@angular/cli": "^9.1.7",
"@angular/compiler-cli": "^9.1.9",
"@angular/language-service": "^9.1.9",
...
}

就个人而言，最好的解决办法是:

ng update @angular/cli @angular/core

为什么？因为迟早，你需要升级到角9 + 和其他解决方案只是降级。

我今天遇到了同样的问题，直到我使用了这个解决方案，这个方案非常好用。

我打开就修好了

Json 文件

并更新下一行

@angular-devkit/build-angular": "^0.803.8"

那就跑吧

Npm i

这个 cmd 解决了问题

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

使用下面的版本为目前的角度版本:

@angular-devkit/build-angular@0.8.9 v6-lts

@angular-devkit/build-angular@0.13.10 v7-lts

@angular-devkit/build-angular@0.803.29 v8-lts

@angular-devkit/build-angular@0.901.13 v9-lts

@angular-devkit/build-angular@0.1002.1 v10-lts

参见最新标签版本 @ angle-devkit/build-angle

小开

只需根据您的版本安装@angle-devkit/build-angle 即可 如果你有棱角 V.8然后尝试这个或找到你的版本，并根据你的棱角版本安装它。

npm i @angular-devkit/build-angular@0.803.29
