问题
I have a created a new Angular Project using Angular-CLI.
The versions I am using are:
Angular-Cli: 1.0.2
Angular: 4.0.0.
I have added a lot of code in it but now, when I build my project using below command I get bunch of errors
ng build --target=production --env=staging
Errors:
/src/app/views/signup/signup.component.html (21,86): Property 'email' is protected and only accessible within class 'SignUpComponent' and its subclasses.
/src/app/views/signup/signup.component.html (26,80): Property 'password' is protected and only accessible within class 'SignUpComponent' and its subclasses.
Can someone please help me in this regard that how can I remove these errors? The build is successful when I omit --target=production BUT in past I got issue that without specifying target browser cache the old deployment version and user has to delete the browser cache to effect latest changes/deployment.
回答1:
Are your email and password properties defined to be private? Are they used in the component's template? Then they need to be changed from private to public.
When you use the Angular CLI's production mode, you automatically get the following:
--aotis set to true--output-hashingis set to all (fingerprints assets)--sourcemapsis set to false--extract-cssis set to true (makes real css files for global styles, while dev makes .js files as a rebuild optimization)- adds service worker if configured in the CLI json
- replaces
process.env.NODE_ENVin modules with theproductionvalue (this is needed for some libs, like react) - runs uglify on the code
See this for more information: https://github.com/angular/angular-cli/pull/6232
It is the aot compiler that is most likely generating these errors. The aot compiler compiles the template in TypeScript and hence generates more type errors. So another alternative is to use the --prod without aot.

You cloud try to set public visibility on email and password.
