Google translate of the above says that after an ng build, the generated hash values are incorrect

@asnowwolf My Chinese isn't very good. Can you help us understand or respond to this issue?

@StephenFluin @intellix
His description of the problem is not detailed enough. I would like to investigate with him in Chinese first and then translate the conclusion into English.

@yushk 你能做一个能复现此问题的最小化工程，上传到 github 的一个开放仓库中吗？另外，你所说的没生效是指没有添加 hash 还是指添加了但每次添加的 hash 都一样？在你没有改动源代码的情况下，每次 build 的 hash 就应该是一样的，这本来就是设计意图。
另外，如果用中文提 issue，请直接 @我，或者提到 angular-cn 仓库下（虽然是文档仓库，不过也可以回复一些简单的技术问题），这样就不会给其他成员造成困扰了。

Hashing plugin used here (sha-384): https://github.com/angular/angular-cli/blob/master/packages/%40angular/cli/models/webpack-configs/browser.ts#L75

Hashing done here: https://github.com/waysact/webpack-subresource-integrity/blob/master/index.js#L175

Are those hashes correct? I'm not sure how to verify the integrity of my bundles to be honest

@asnowwolf hi, you are very friendly. I have a very strange problem. Can I ask you by some other way. After I update to the latest version of Angular CLI. Every time I build need 40 minutes.

[asnowwolf]

@zuo305 Yes, if you speak Chinese too, please add my wechat: asnowwolf .

package.json自己加参数 --output-hashing=bundles
demo：
"build": "node --max_old_space_size=4096 ./node_modules/@angular/cli/bin/ng build --aot -prod --output-hashing=bundles --base-href /v2/",
