javascript - 错误 : bundle initial-es5 exceeded maximum budget. 预算 6.00 MB 未满足 133.51 kB 总共 6.13 MB

Question

我有一个升级到 11 的 Angular 应用程序。
我做了一个> ng build --prod我看到了这些信息:

√ Browser application bundle generation complete.
√ ES5 bundle generation complete.

但我也收到此错误:

Error: bundle initial-es5 exceeded maximum budget. Budget 6.00 MB was not met by 133.51 kB with a total of 6.13 MB.

但我前段时间已经更改了预算大小:

 "budgets": [
                {
                  "type": "initial",
                  "maximumWarning": "4mb",
                  "maximumError": "6mb"
                },
                {
                  "type": "anyComponentStyle",
                  "maximumWarning": "6kb",
                  "maximumError": "10kb"
                }
              ]

当然，我可以再次增加尺寸。但是，当然，这不是您想要做的。

如何减少 dist 文件夹？
谢谢

有时，当您的应用程序增长时，没有其他选择，您必须提高 angular.json 中的批量大小限制才能编译。
但首先您应该尝试删除无用的代码、依赖项、 Assets 、样式等，以减小大小。
