我正在为 Angular 开发一个小型 npm 包,它基本上是一个指令,可以在您放置的元素上进行拖动/移动。我昨天确实设法发布了它(甚至认为这需要一段时间,因为这是我第一次将 angular 包发布到 npm)。我用来ngc
编译 Angular 的代码。用于捆绑的汇总和用于缩小的 unglify。
现在,我想修复我发现的几个错误。我修复了它们,运行了编译器,运行了汇总等。但是汇总一直向我显示@angular/core
未定义的内容,因此它将其视为外部依赖项,并且 - 我无法解决的问题 -this is undefined
在我的两个文件中(https: //github.com/rollup/rollup/wiki/Troubleshooting#this-is-undefined)。无论如何,模块已经构建,我能够发布并使用它。问题是,当我尝试ng build --prod --aot
使用包含该软件包的应用程序时,它会大喊:
ERROR in Unexpected value
'DragOnlyModule in .../ng-dragonly-demo/node_modules/ng-dragonly/index.d.ts'
imported by the module
'AppModule in .../ng-dragonly-demo/src/app/app.module.ts'.
Please add a @NgModule annotation.
我猜这是因为我上面写的警告。所以我试图修复它们,但没有成功。我至少能够通过添加到文件中来修复@angular/core
警告,但仍然存在。我还意识到我编译的文件与昨天的不同。exports: ['@angular/core']
rollup.config.js
this is undefined
在几次提交之前编译的文件等:
import { NgModule } from "@angular/core";
import { DragOnlyDirective } from "./dragonly.directive";
var DragOnlyModule = (function () {
function DragOnlyModule() {
}
DragOnlyModule.decorators = [
{ type: NgModule, args: [{
declarations: [DragOnlyDirective],
exports: [DragOnlyDirective]
},] },
];
/** @nocollapse */
DragOnlyModule.ctorParameters = function () { return []; };
return DragOnlyModule;
}());
export { DragOnlyModule };
//# sourceMappingURL=dragonly.module.js.map
今天编译的文件:
var __decorate = (this && this.__decorate) || function (decorators, target, key, desc) {
var c = arguments.length, r = c < 3 ? target : desc === null ? desc = Object.getOwnPropertyDescriptor(target, key) : desc, d;
if (typeof Reflect === "object" && typeof Reflect.decorate === "function") r = Reflect.decorate(decorators, target, key, desc);
else for (var i = decorators.length - 1; i >= 0; i--) if (d = decorators[i]) r = (c < 3 ? d(r) : c > 3 ? d(target, key, r) : d(target, key)) || r;
return c > 3 && r && Object.defineProperty(target, key, r), r;
};
import { NgModule } from "@angular/core";
import { DragOnlyDirective } from "./dragonly.directive";
var DragOnlyModule = (function () {
function DragOnlyModule() {
}
DragOnlyModule = __decorate([
NgModule({
declarations: [DragOnlyDirective],
exports: [DragOnlyDirective]
})
], DragOnlyModule);
return DragOnlyModule;
}());
export { DragOnlyModule };
//# sourceMappingURL=dragonly.module.js.map
看起来装饰器的创建方式不同,我真的不知道我是否更改了tsconfig.json
文件或任何其他配置文件中的任何内容。
我正在执行构建模块的步骤是:
node_modules/.bin/ngc -p tsconfig.json
node_modules/.bin/rollup -c
node_modules/.bin/uglify ... (that's a long one)
我的文件结构是:
app
|
- src/
- dragonly.directive.ts
- dragonly.module.ts
- index.ts
- package.json
- tsconfig.json
- rollup.config.js
...我正在将输出编译到dist/
应用程序根目录中的目录中。
