angular - Job name "..getProjectMetadata" does not exist

Question

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:

uninstall -global angular/cli
uninstall angular/cli
go back to my last package.json
delete node_module folder
delete repo

This error continues to show.

My stacktrace is :

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

angular-errors.log :

[error] Error: Job name "..getProjectMetadata" does not exist.

这似乎是@angular-devkit/build-angular.. 的问题。尝试将其降级到特定版本：

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

score 19 · Accepted Answer

也跑npm i @angular-builders/custom-webpack@8.4.1 --save

对我来说， Occian 的回答还不够，我还必须@angular-builders/custom-webpack从latestto更改8.4.1，因为它也有build-angular依赖关系。这是如何弄清楚的：

npm list @angular-devkit/build-angular

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 2 个版本的软件包，这就是错误仍然会出现的原因。

就个人而言，最好的解决方案是：

ng update @angular/cli @angular/core

为什么？因为迟早你需要升级到 Angular 9+，而其他解决方案只是降级它。

我今天遇到了同样的问题，直到我使用了这个解决方案并且这个解决方案运行良好。

将以下版本用于当前的角度版本：

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

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

此命令暂时修复了这种情况：

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

我的 Jenkins 构建需要我运行npm audit fix命令来下载依赖项。此命令使相同的错误再次出现。任何人都知道如何让审计命令忽略 angula-devkit？

如果您使用 npm audit fix，请找到您尝试修复的软件包并恢复到稳定版本，并注意漏洞。

score 3 · Accepted Answer

我通过打开修复它

包.json 文件

并在下一行更新

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

然后运行

npm 我

我遇到了同样的问题，并通过将@angular-devkit/build-angular.版本降级0.803.24为 Occian Fumnanya Dia 在他上面的回答中所说的那样解决了如果降级版本后仍然出现相同的错误，请尝试删除文件夹platforms并重新运行ionic cordova run <platform>. 替换<platform>为android或ios。

它将plaforms用新东西重新创建文件夹。

希望能帮助到你。

不要删除整个 node_modules 文件夹，只需重命名它并尝试

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

请在我的角度包版本下面找到 -

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

"@angular/compiler-cli": "8.2.0",
"@angular/core": "8.2.0",

根据我的经验，您正在使用的一个新模块是为 angular9 设计的，如果可能的话，您应该升级您的导入：

 "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",
   ...
}

只需根据您的版本安装@angular-devkit/build-angular，就像您有角度 V.8 一样，然后尝试这个或找到您的版本并根据您的角度版本安装它。

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