我试图为我的项目运行 jspsych 实验。实验是关于现在显示图像的幻灯片。当我运行该应用程序时，它在控制台中给我一个错误，说没有加载插件，并且在进入显示图像的第二步之后，它会引发另一个错误，说未定义不是一个对象。我想我已经正确导入了插件，我没有做错什么。我已经发布了我所有的截图。

这是我的 app.js

import React from 'react'
import { Experiment } from 'jspsych-react';
import { timelineFactory } from './timeline';
import callbackImageKeyboardResponsePlugin from       './callbackImageKeyboardResponsePlugin';



function App() {
const callback = (targetID) => console.log(targetID);
const timeline = timelineFactory(callback);
return (
    <div>
        <Experiment
            settings={{ timeline }}
            plugins={{ callbackImageKeyboardResponsePlugin }}
        />

    </div>
  )
 }
export default App

这是我的 timline.js

import { jsPsych } from 'jspsych-react'
import callbackImageKeyboardResponsePlugin from "./callbackImageKeyboardResponsePlugin.js"
const post_trial_gap = function () {
 return Math.floor(Math.random() * jitter) + iti;
};
const stim_duration = 200;
const iti = 300;
const jitter = 200;
const plugin_name = callbackImageKeyboardResponsePlugin;
export function timelineFactory(callback) {
const start_callback = function () {
 callback('start')
};
const stop_callback = function () {
 callback('stop')
};
let targets = [];
var imageNumber;
var fileName;
var toPush;
for (var i = 0; i < 10; i++) {
imageNumber = Math.floor(Math.random() * (901 - 1) + 1);
if (imageNumber <= 9) {
  fileName = "static/00000" + imageNumber + ".jpg";
  toPush = { 'stimulus': fileName };
}
else if (imageNumber > 9 && imageNumber <= 99) {
  fileName = "static/0000" + imageNumber + ".jpg";
  toPush = { 'stimulus': fileName };
}
else {
  fileName = "static/000" + imageNumber + ".jpg";
  toPush = { 'stimulus': fileName };
}
if (targets.includes(toPush)) {
  i -= 1;
}
targets.push(toPush);
}
// Create timeline
const timeline = [];
const welcome_block = {
type: 'callbackImageKeyboardResponsePlugin',
stimulus: "In this exercise, you will be shown a series of quickly moving pictures. In between each picture, you will see a <strong>+</strong>. Please focus on this when there is not an image on the screen. This exercise contains imagery that some may find disturbing. User beware. Press any key to begin.",
post_trial_gap: 5000,
on_start: start_callback
};
timeline.push(welcome_block);
const test_trials = {
stimulus: 'stimulus',
type: plugin_name,
timeline: targets,
trial_duration: function () {
  return jsPsych.randomization.sampleWithoutReplacement([250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750], 1)[0];
},
stimulus_duration: stim_duration,
post_trial_gap: post_trial_gap(),
on_start: function () {
  console.log(this)}};
timeline.push(test_trials);
const end_block = {
type: 'callbackImageKeyboardResponsePlugin',
stimulus: "Thanks for participating!",
post_trial_gap: 500,
on_start: stop_callback
};
timeline.push(end_block);
    return timeline;
   }

这是我的错误信息。 在此处输入图像描述

如果你需要，我有链接 github repo
