我正在尝试按照本指南将ECharts集成到Ionic(4)应用程序中:
https://golb.hplar.ch/2017/02/Integrate-ECharts-into-an-Ionic-2-app.html
我按如下方式安装了所有模块(我添加了“离子信息”输出):
D:\e-charts-debug>ionic info

我还修改了tsconfig.json和app.module.ts,如下所示:
"compilerOptions": {
"allowSyntheticDefaultImports": true,
"declaration": false,
...
"baseUrl": ".",
"paths": {
"echarts": ["node_modules/echarts/dist/echarts.min.js"]
}
}
app.module.ts:
import {NgxEchartsModule} from "ngx-echarts";
...
@NgModule({
declarations: [
MyApp,
HomePage
],
imports: [
BrowserModule,
NgxEchartsModule,
IonicModule.forRoot(MyApp)
],
...
在home.ts和home.html中,我刚刚添加了一个图表,例如:
home.ts:
import { EChartOption } from 'echarts';
@Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
chartOption: EChartOption = {
xAxis: {
type: 'category',
data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
},
yAxis: {
type: 'value'
},
series: [{
data: [820, 932, 901, 934, 1290, 1330, 1320],
type: 'line'
}]
}
}
home.html的:
<ion-content padding>
<div echarts [options]="chartOption" class="demo-chart"></div>
</ion-content>
但是,当我提供应用程序时,我收到此错误:
Error: Uncaught (in promise): TypeError: Object(...) is not a function

它只是一个导入或版本问题?如果是这样,我该如何解决?
谢谢你的帮助!
编辑:
像下面的答案建议,我试图安装较旧的ngx-echarts版本(我的角度版本是5.2.10):
D:\e-charts-2.0.0>npm install echarts -S
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.4 (node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.4: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
+ echarts@4.2.0-rc.2
added 2 packages in 38.188s
D:\e-charts-2.0.0>npm install ngx-echarts@2.2.0 -S
npm WARN ngx-echarts@2.2.0 requires a peer of echarts@>=3.1.1 but none is installed. You must install peer dependencies yourself.

added 1 package in 31.035s

+ @types/echarts@4.1.1
added 1 package in 16.213s
现在我在“echarts peer”上看到一个奇怪的npm警告,因为我的版本应该没问题.
当我使用离子服务启动我的应用程序时,我收到此错误:

我使用了一个新项目,执行相同的导入过程,但安装的ngx-echarts版本不同.

"src/**/*.spec.ts",
"src/**/__tests__/*.ts"

}
包括< script src =“../ node_modules / echarts / dist / echarts.min.js”>< / script>在index.html文件中,错误仍然存??在:
Error: Uncaught (in promise): ReferenceError: echarts is not defined
ReferenceError: echarts is not defined
解决方法:
您似乎使用的是Angular 5x版本,但您使用的ngx-echarts版本与Angular 6兼容.从这个警告看来 –
npm WARN ngx-echarts@4.0.0 requires a peer of @angular/core@^6.0.0-rc.0 || >=6.0.0 but none is installed.
它还在ngx-echarts的README中提到过
Latest version @npm:
v4.0.0 for Angular >= 6
v2.3.1 for Angular < 6 (Please refer to https://github.com/xieziyu/ngx-echarts/blob/v2.x/README.md)
Github branches:
master for Angular >= 6
v2.x for Angular < 6
这是Github https://github.com/xieziyu/ngx-echarts/issues/113中的类似问题
所以你可以安装它像 –
npm install ngx-echarts@2.2.0 -S
或者您可以在package.json中为ngx-echarts指定版本
更新的答案
在查看您的项目后,您的离子应用程序似乎未正确加载echarts.min.js的路径.所以我在离子项目的根index.html文件中包含了echarts.min.js的路径.它现在正在运作 –
这是添加的代码 –
<html>
<head>
<script src="../node_modules/echarts/dist/echarts.min.js"></script>
</head>
<body>
<my-app>loading</my-app>
</body>
</html>
您需要根据项目结构调整路径.这是一个stackblitz示例,我使用您使用的相同包版本创建.
https://stackblitz.com/edit/angular-eml14x
您也可以在此处查看2x版本的指南.
https://github.com/xieziyu/ngx-echarts/tree/v2.x
第二次更新
上面的更改适用于角度cli,但对于离子,脚本文件应该在构建后的www文件夹中可用,因此您可以从../node_modules/echarts/dist/echarts.min复制echarts.min.js文件.js到你的src / assets文件夹并使用index.html中的以下路径.
<script src="assets/echarts.min.js"></script>
请检查tsconfig.json文件的位置,echarts库的路径取决于baseUrl中给出的路径.
检查一下
