npm 运行构建生产不分发生产

Question

I have a problem with my Angular project. Especially on the build of the project.

When I build my Angular poject with

ng build

it creates the dist-folder with the correct build. When I use the following command:

ng build --prod

it creates the production build (correct)

When I use NPM (used by build server) I use this:

run build

But I want the production build. Whatever I do, it doesn't work locally or on the buildserver. I used these:

npm run build --prod
npm run build --target=production
npm run build --environment=prod
npm run build --environment=production
npm run build --env=production
npm run build --env=prod
npm run build *projectname* --environment=production
npm run build *projectname* --env=production
npm run build *projectname* production

And probably a lot more. It just does not build the production!

I have a environment.prod.ts ( production = true ). It is set in the Angular.json. I have no clue what I am doing wrong.

Answer 1

npm run build should have the script in the package.json have a look there and maybe add the line in the scripts

{
...
 scripts: {
    "build": "ng build --prod"
 },
...
}

this should do the trick

Answer 2

What you can do is update the build script in the package.json as

scripts:{
   "build": "npm run ng build --",
   "ng": "ng"
}

-- allows you to pass arguments to a script.

Then you can pass the arguments to ng build like ng build --prod

Answer 3

You could also use -- to separate the params passed to npm command itself and params passed to your script. So the correct syntax for your case would be:

npm run build -- --prod

Answer 4

Try this if your environment is "production":
npm run build -- --configuration=production
or this if it's "prod":
npm run build -- --configuration=prod

if you don't specify the "configuration" parameter name you may see this error:
npm run build -- --prod
Error: Unknown argument: prod
npm run build -- --production
Error: Unknown argument: production
