我正在使用yourSwipeRefreshLayout.setOnRefreshListener(
new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
//update your adapter with a new list of channels?
KanalAdapter updatedKanalAdapter = new KanalAdapter(context, channelbaba);
mListView.setAdapter(updatedKanalAdapter);
mListView.invalidateViews();
yourSwipeRefreshLayout.setRefreshing(false);
}
});
部署示例Bluemix应用。如果我的应用程序代码中不需要node.js包，那么一切正常。但如果我需要代码中的Q包，则应用程序部署将失败。
这是我的应用代码 -
Q但是，当我检查日志/*eslint-env node*/
var express = require('express'),
cfenv = require('cfenv'),
//bodyParser = require('body-parser'),
//multer = require('multer'),
Q = require('Q');
var app = express();
app.set('view engine', 'pug');
app.use(express.static(__dirname + '/views'));
app.get('/', function (req, res) {
res.render('index');
});
app.listen(appEnv.port, '0.0.0.0', function() {
console.log("server starting on " + appEnv.url);
});
模块确实已安装并显示如下。

，一切正常，应用程序已部署并成功启动。我也在我的机器上进行了本地测试，它的工作非常好。
有任何建议或解决方案吗？谢谢！
答案 0 :(得分：2)
请尝试以下代码：
var Q = require('q');
q模块名称为q，而不是Q。
答案 1 :(得分：1)
问题的关键是这个错误：
Error: Cannot find module 'Q'
模块的名称不是Q，而是q。更改该值，它将解决您的问题。
