刚刚从 ng8 升级到 ng11。
当我运行 ngserve 时它工作正常，但是当我运行 build 进行生产时我收到以下错误：
生成 ES5 包以进行差异加载...
发生未处理的异常：C:\P.....\src\app\9-es2015.dce42a686e45767441f2.js：无法读取未定义的属性“split”
我尝试删除代码以查看导致问题的原因，并在组件中找到以下代码，我将枚举更改为它可以工作的硬编码数字，或者如果删除 console.log。
看来是es2015的问题，改成es5解决了。
import {FormTableData} from '../../../form/service/type/form-table-data';
import {FormFieldTypes} from '../../../form/service/type/form-field-types.enum';
export class FormEditorFormData {
formData: FormTableData;
fieldType = FormFieldTypes;
arr: string[];
constructor(n: number,s:string) {
let type = 0;
const option: string[] = [];
for (const s of this.arr) {
if (s != null) {
switch (type) {
case FormFieldTypes.checkbox:
const cap = 'pp';
option.forEach( (currentValue) => {
console.log(cap);
});
break;
}
}
}
}
}
表单字段类型：
export enum FormFieldTypes {
text = 10,
checkbox = 20,
numeric = 30,
option = 40,
date = 50,
combo = 60,
xiny = 70,
file = 80,
picture = 90,
break = 100,
textArea = 110,
actionButton = 998,
none = 999
}
