我正在使用3.4.0版的React Boilerplate,当从语义UI反应导入组件时,出现以下错误:
Dynamic page loading failed TypeError: __webpack_require__.i(...) is not a function
at new Button (Button.js:83)
at eval (ReactCompositeComponent.js:295)
at measureLifeCyclePerf (ReactCompositeComponent.js:75)

at ReactDOMComponent._createInitialChildren (ReactDOMComponent.js:691)
at ReactDOMComponent.mountComponent (ReactDOMComponent.js:516)
我正在使用导入按钮组件
import { Button } from 'semantic-ui-react'
但是最让我惊讶的是,对于某些组件,导入有效:
import { Grid } from 'semantic-ui-react'
有效。
此外,当我在render函数之外记录组件时:
console.log(<Button></Button>)
我得到了相关日志:
{$$typeof: Symbol(react.element), type: ƒ, key: null, ref: null,
props: {…}, …}
我正在使用Webpack 2.6.1
答案 0 :(得分:0)
好的,问题解决了(在StackOverflow上发布一晚零十分钟后,我找到了解决方法:p)
我正在使用语义ui react,其版本兼容我正在使用的react 16而不是react 15。
然后我使用以下命令将语义UI反应降级为0.81.3版本
MarkerOptions().position(paris).title("Marker in Ocean"));
try {
String sql = "SELECT
marker.markerLat,marker.markerLon,marker.markerDate
FROM marker LEFT JOIN tripMarker ON" +
" marker.markerID = tripMarker.markerID LEFT
JOIN userTrip ON userTrip.tripID =
tripMarker.tripID " +
"WHERE userTrip.userID = '" + User.UserLoggedOn
+ "';";
Cursor cursor = db.rawQuery(sql, null);
while (cursor.moveToNext()) {
double lat =
cursor.getDouble(cursor.getColumnIndex("markerLat"));
System.out.println(lat);
double lon =
cursor.getDouble(cursor.getColumnIndex("markerLon"));
System.out.println(lon);
LatLng latLng = new LatLng(lat, lon);
MarkerOptions markerOptions = new
MarkerOptions();
markerOptions.position(latLng);
map.addMarker(markerOptions.title(cursor.getString(
cursor.getColumnIndex("markerDate"))));
}
}catch (Exception e){
e.printStackTrace();
}
