发生未处理的异常：项目不存在。 Angular SSR

Question

I implemented Angular universal in my angular project but after that whenever I am building the project I am getting below error

[error] Error: Project does not exist. at WorkspaceNodeModulesArchitectHost.findProjectTarget (/home/atif/Desktop/Code/BlogFE/blogui/BlogApp/node_modules/@angular/cli/node_modules/@angular-devkit/architect/node/node-modules-architect-host.js:122:19) at WorkspaceNodeModulesArchitectHost.getBuilderNameForTarget (/home/atif/Desktop/Code/BlogFE/blogui/BlogApp/node_modules/@angular/cli/node_modules/@angular-devkit/architect/node/node-modules-architect-host.js:23:39) at RunCommand.runSingleTarget (/home/atif/Desktop/Code/BlogFE/blogui/BlogApp/node_modules/@angular/cli/models/architect-command.js:174:55) at RunCommand.runArchitectTarget (/home/atif/Desktop/Code/BlogFE/blogui/BlogApp/node_modules/@angular/cli/models/architect-command.js:217:35) at RunCommand.run (/home/atif/Desktop/Code/BlogFE/blogui/BlogApp/node_modules/@angular/cli/commands/run-impl.js:14:25) at RunCommand.validateAndRun (/home/atif/Desktop/Code/BlogFE/blogui/BlogApp/node_modules/@angular/cli/models/command.js:134:39) at async Object.r unCommand (/home/atif/Desktop/Code/BlogFE/blogui/BlogApp/node_modules/@angular/cli/models/command-runner.js:201:24) at async default_1 (/home/atif/Desktop/Code/BlogFE/blogui/BlogApp/node_modules/@angular/cli/lib/cli/index.js:62:31)

Basically I get this error whenever I run npm run build:ssr

Answer 1

The issue is resolved as the code changes done in package.json by running the command

ng add @ng-toolkit/universal

referred to wrong project name

"build:ssr": "ng build --prod && ng run **universal-website**:server:production && npm run compile:server"

which I replaced to

"build:ssr": "ng build --prod && ng run blogapp:server:production && npm run compile:server",
