升级到V15.1.2后无法通过Angular CLI生成组件

Question

My team recently upgraded a project to Angular V15.1.2 and since then I've not been able to run simple cli commands such as ng g c components/test . I'm not having the same issue in my other project that is running Angular 15.0.1, so at least that should rule out an error with my version of NPM or Node. The following is the error that I receive:

An unhandled exception occurred: Cannot destructure property 'aliases' of 'collection.description.schematics[schematicName]' as it is undefined. See "C:\Users\david\AppData\Local\Temp\ng-4fyV7s\angular-errors.log" for further details.

The following is the further details mentioned above:

[error] TypeError: Cannot destructure property 'aliases' of 'collection.description.schematics[schematicName]' as it is undefined. at GenerateCommandModule.getSchematics (C:\Projects\GitHub\app\node_modules@angular\cli\src\commands\generate\cli.js:141:29) at getSchematics.next () at GenerateCommandModule.getSchematicsToRegister (C:\Projects\GitHub\pau-pe-shutdownreporting\shutdown-app\node_modules@angular\cli\src\commands\generate\cli.js:158:76) at async GenerateCommandModule.builder (C:\Projects\GitHub\app\node_modules@angular\cli\src\commands\generate\cli.js:35:55) at async runCommand (C:\Projects\GitHub\app\node_modules@angular\cli\src\command-builder\command-runner.js:113:5) at async default_1 (C:\Projects\GitHub\app\node_modules@angular\cli\lib\cli\index.js:70:16)

This is on a Windows 10 machine within a Git Bash terminal within VSCode. Others on my team are also having the same issue, so it may be something with the project setup after the upgrade.

Answer 1

Evidently my issue was caused by some issues while the project was being upgraded that caused the angular packages to not all be upgraded correctly. If you are running into this issue, check that @angular/compiler-cli has been upgraded to the same level as @angular/cli.

Answer 2

Hi I was having the same problem today, I fixed with:

npm uninstall -g @angular/cli
npm install -g @angular/cli@latest


npm install
ng g c components/test
