我是新手，我收到此错误，无法弄清楚为什么请建议：看起来错误在 Uppy 内部。
我按照Uppy Tutorial docs之类.use(Dashboard, {...的方法进行操作，但突然出现此错误，我尝试回溯但没有运气
我从我的设备中添加文件，然后发生错误，没有断点被击中我丢失的任何地方
这是我的简单Uppy：
import React from "react";
import "@uppy/core/dist/style.css";
import "@uppy/status-bar/dist/style.css";
import "@uppy/drag-drop/dist/style.css";
import "@uppy/progress-bar/dist/style.css";
import "@uppy/dashboard/dist/style.css";
import "./styles.css";
const Uppy = require("@uppy/core");
// const Dashboard = require("@uppy/dashboard");
const GoogleDrive = require("@uppy/google-drive");
const Dropbox = require("@uppy/dropbox");
const Instagram = require("@uppy/instagram");
const Webcam = require("@uppy/webcam");
const Tus = require("@uppy/tus");
const {
Dashboard,
DashboardModal,
DragDrop,
ProgressBar,
} = require("@uppy/react");
class DashboardUppy extends React.Component {
constructor(props) {
super(props);
this.form = React.createRef();
this.state = {
showInlineDashboard: false,
open: false,
};
this.uppy = new Uppy({
id: "uppy1",
autoProceed: false,
debug: true,
allowMultipleUploads: true,
showSelectedFiles: true,
restrictions: {
maxFileSize: 1000000,
maxNumberOfFiles: 100,
minNumberOfFiles: 1,
allowedFileTypes: ['image/*', 'video/*'],
},
onBeforeFileAdded: (currentFile, files) => {
console.log(files);
const modifiedFile = Object.assign({}, currentFile, {
name: currentFile + Date.now(),
});
if (!currentFile.type) {
// log to console
this.uppy.log(`Skipping file because it has no type`);
// show error message to the user
this.uppy.info(`Skipping file because it has no type`, "error", 500);
return false;
}
return modifiedFile;
},
})
.use(Tus, { endpoint: "https://master.tus.io/files/" })
.use(GoogleDrive, { companionUrl: "https://companion.uppy.io" })
.use(Dropbox, {
companionUrl: "https://companion.uppy.io",
})
.use(Instagram, {
companionUrl: "https://companion.uppy.io",
})
.use(Webcam, {
onBeforeSnapshot: () => Promise.resolve(),
countdown: false,
modes: ["video-audio", "video-only", "audio-only", "picture"],
mirror: true,
facingMode: "user",
locale: {
strings: {
// Shown before a picture is taken when the `countdown` option is set.
smile: "Smile!",
// Used as the label for the button that takes a picture.
// This is not visibly rendered but is picked up by screen readers.
takePicture: "Take a picture",
// Used as the label for the button that starts a video recording.
// This is not visibly rendered but is picked up by screen readers.
startRecording: "Begin video recording",
// Used as the label for the button that stops a video recording.
// This is not visibly rendered but is picked up by screen readers.
stopRecording: "Stop video recording",
// Title on the “allow access” screen
allowAccessTitle: "Please allow access to your camera",
// Description on the “allow access” screen
allowAccessDescription:
"In order to take pictures or record video with your camera, please allow camera access for this site.",
},
},
})
.on("file-added", (file) => {
const { setFiles } = props;
setFiles(file);
})
}
componentWillUnmount() {
this.uppy.close();
}
render() {
this.uppy.on("complete", (result) => {
console.log(
"Upload complete! We’ve uploaded these files:",
result.successful
);
});
return (
<div>
<div>
<Dashboard
uppy={this.uppy}
plugins={["GoogleDrive", "Webcam", "Dropbox", "Instagram"]}
metaFields={[
{ id: "name", name: "Name", placeholder: "File name" },
]}
open={this.state.open}
target={document.body}
onRequestClose={() => this.setState({ open: false })}
/>
</div>
</div>
);
}
}
export default DashboardUppy;
我像这样使用它没什么特别的：
import React, { useState } from "react";
import FileList from "./FileList";
import FileForm from "./FileForm";
import DashboardUppy from "./DashboardUppy";
import { Container, Grid } from "@material-ui/core";
const CreateContent = () => {
const [file, setItems] = useState();
const [show, showDashboardUppy] = useState(true);
return (
<Container maxWidth="lg">
{show ? (
<DashboardUppy showDashboardUppy={showDashboardUppy}/>
) : (
<Grid container spacing={3}>
<Grid item lg={4} md={6} xs={12}>
<FileList setItems={setItems} />
</Grid>
<Grid item lg={8} md={6} xs={12}>
<FileForm file={file} />
</Grid>
</Grid>
)}
</Container>
);
};
export default CreateContent;
这是 package.json
