在React应用程序中找不到包含npm包的模块

我有一个从API获取一些数据的React应用程序。 数据是过境数据，并与协议缓冲区序列化，所以我使用gtfs-realtime-bindings.js包来反序列化它。 这也使用了ProtoBuf.js和ByteBuffer.js。 但是，当我运行我的开发服务器，我在浏览器中得到这个错误：

./node_modules/protobufjs/ProtoBuf.js Module not found: `/Users/Ben/React/subway- checker/node_modules/ByteBuffer/ByteBuffer.js` does not match the corresponding path on disk `bytebuffer`. 

我真的不知道如何开始debugging。 这可能是一个Webpack的问题？ 如果有帮助诊断，我正在使用create-react-app。

对于上下文，下面是导致错误的文件中的其余代码：

从'gtfs-realtime-bindings'导入GtfsRealtimeBindings; 从“请求”导入请求;

 function getFeedData (sub) { var feedId; switch (sub) { case '1' || '2' || '3' || '4' || '5' || '6' || 'S': feedId = 1; break; case 'A' || 'C' || 'E': feedId = 26; break; case 'N' || 'Q' || 'R' || 'W': feedId = 16; break; case 'B' || 'D' || 'F' || 'M': feedId = 21; break; case 'L': feedId = 2; break; case 'G': feedId = 31; break; } var requestSettings = { method: 'GET', uri: 'http://datamine.mta.info/mta_esi.php?key=YOUR_KEY_HERE&feed_id=2', encoding: null }; request(requestSettings, function (error, response, body) { if (!error && response.statusCode == 200) { var feed = GtfsRealtimeBindings.FeedMessage.decode(body); return { feed: feed }; } }); } function reverseStop (sub, stop) { var stopIdN var stopIdS var stopData = require('./stops'); var invalidEntries = 0; function filterByName (item) { if (item.stop_name == stop && item.stop_id.charAt(0) == sub) { return true; } invalidEntries++; return false; } var stopObjs = stopData.filter(filterByName); for (var i = 0; i < stopObjs.length; i++) { if (stopObjs[i].stop_id.charAt(stopObjs[i].stop_id.length - 1) == 'N') { stopIdN = stopObjs[i].stop_id; } else if (stopObjs[i].stop_id.charAt(stopObjs[i].stop_id.length - 1) == 'S') { stopIdS = stopObjs[i].stop_id; } } return { stopIdN: stopIdN, stopIdS: stopIdS }; } var isDelayN = (function (sub, stop) { var arrivals = []; var delays = []; reverseStop(sub, stop); getFeedData(sub); (function () { var invalidEntries = 0; var feedObjs = getFeedData.feed.filter(function (feedObj) { if (feedObj.entity.trip_update.stop_time_update.stop_id == reverseStop.stopIdN) { return feedObj.entity.trip_update.stop_time_update; } }); for (var i = 0; i < feedObjs.length; i++) { arrivals.push(feedObjs.arrival.time.low); delays.push(feedObjs.arrival.delay); } })(); var nextArrival = Math.min(...arrivals); var delayIndex = arrivals.findIndexOf(nextArrival); var delay = delays.delayIndex; if (delay === null || Math.ceil(delay / 60) <= 5) { var noDelay = Math.ceil((nextArrival - getFeedData.feed.header.timestamp.low) / 60); return { noDelay: noDelay }; } else { var yesDelay = Math.ceil(delay / 60); return { yesDelay: yesDelay }; } })(); var isDelayS = (function (sub, stop) { var arrivals = []; var delays = []; reverseStop(stop); getFeedData(sub) .then(function (feed) { var invalidEntries = 0; var feedObjs = feed.filter(function (feedObj) { if (feedObj.entity.trip_update.stop_time_update.stop_id == reverseStop.stopIdS) { return feedObj.entity.trip_update.stop_time_update; } }); for (var i = 0; i < feedObjs; i++) { arrivals.push(feedObjs.arrival.time.low); delays.push(feedObjs.arrival.delay); } }); var nextArrival = Math.min(...arrivals); var delayInex = arrivals.findIndexOf(nextArrival); var delay = delays.delayIndex; if (delay === null || Math.ceil(delay / 60) <= 5) { var noDelay = Math.ceil((nextArrival - getFeedData.feed.header.timestamp.low) / 60); return { noDelay: noDelay }; } else { var yesDelay = Math.ceil(delay / 60); return { yesDelay: yesDelay }; } })(); export { isDelayN, isDelayS }; 

我意识到代码可能需要很多的上下文。 代替张贴我的所有组件，并有一个不合理的长期职位，这里是完整的Github回购，因为它现在： https ： //github.com/benuchadnezzar/subway-checker
