运行后ng update ng-zorro-antd
我们得到:
[error] TypeError: Class extends value undefined is not a constructor or null
at Object.<anonymous> (C:\Users\<user name>\Desktop\Work\<project name>\node_modules\ng-zorro-antd\schematics\ng-update\upgrade-rules\checks\calendar-input-rule.js:4:49)
这也发生在一个全新的 Angular 8 项目中。升级到 Angular 9 工作正常,但只有 NG-Zorro 更新失败。
这些是calendar-input-rule.js
错误中文件的内容:
"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
const schematics_1 = require("@angular/cdk/schematics");
class CalendarTemplateRule extends schematics_1.MigrationRule {
constructor() {
super(...arguments);
this.ruleEnabled = this.targetVersion === schematics_1.TargetVersion.V9;
}
visitTemplate(template) {
schematics_1.findInputsOnElementWithTag(template.content, 'nzCard', ['nz-calendar'])
.forEach(offset => {
this.failures.push({
filePath: template.filePath,
position: template.getCharacterAndLineOfPosition(offset),
message: `Found deprecated input "nzCard" component. Use "nzFullscreen" to instead please.`
});
});
}
}
exports.CalendarTemplateRule = CalendarTemplateRule;
//# sourceMappingURL=calendar-input-rule.js.map
我看到有人说这可能是由于循环依赖,但应用程序运行正常,所以错误可能来自 NG-Zorro 的导入?这有什么解决方法吗?
