如何在特定环境下构建角度cli项目

Question

I used angular cli 6.2.4 project and created an angular6 project.

I want to use the environment/configuration option to create the specific configuration for dev and prod.

I thought that I need to execute ng build --configuration=production

but that gives me the following error:

ERROR in: Encountered undefined provider! Usually, this means you have a circular dependency. This might be caused by using 'barrel' index.ts files.

running ng build without any parameter doesn't give me any issues.

in src/environments I created an environment.dev.ts besides that environment.prod.ts that already existed.

this is my full angular.json file:

what am I missing ?

Answer 1

I should have listened to @Suresh-Kumar-Ariya from the beginning but that subject was a bit confusing form me.

@user184994 also helped me after reading this post for the 5th time that I really should check my providers since it's a problem only detected when I use AOT.

so anyhow I use Document as a provider, I read somewhere that I needed to use that in order to use document which was false. removing it solved the problem

thanks all
