解析服务器迁移到IBM bluemix [英] Parse server migration to IBM bluemix
问题描述
我试图在ibm bluemix中使用nodejs运行解析服务器,但是在解析服务器PromiseRouter文件中抛出错误.
I am trying to run parse server with nodejs in ibm bluemix but it is throwing an error in parse server PromiseRouter file.
PromiseRouter.js:48
throw _iteratorError;
^
ReferenceError: Symbol is not defined
我该如何解决
我的App .js
var express = require('express');
var ParseServer = require('parse-server').ParseServer;
var app = express();
var port = process.env.PORT || 1337;
// Specify the connection string for your mongodb database
// and the location to your Parse cloud code
var api = new ParseServer({
databaseURI: 'mongodb://IBM_MONGO_DB',
cloud: './cloud/main.js', // Provide an absolute path
appId: 'MYAPPID',
masterKey: 'MYMASTER_KEY', //Add your master key here. Keep it secret!
serverURL: 'http://localhost:' + port + '/parse' // Don't forget to change to https if needed
});
app.use('/parse', api);
app.get('/', function(req, res) {
res.status(200).send('Express is running here.');
});
app.listen(port, function() {
console.log('parse-server-example running on port ' + port + '.');
});
响应:
/Applications/MAMP/htdocs/IBM_bluemix/Development/my_node_app/node_modules/parse-server/lib/PromiseRouter.js:48
throw _iteratorError;
^
ReferenceError: Symbol is not defined

这是PromiseRouter.js中的函数,会引发错误
This is the function in PromiseRouter.js that is throwing an error
PromiseRouter.prototype.merge = function (router) {
var _iteratorNormalCompletion = true;
var _didIteratorError = false;
var _iteratorError = undefined;
try {
for (var _iterator = router.routes[Symbol.iterator](), _step; !(_iteratorNormalCompletion = (_step = _iterator.next()).done); _iteratorNormalCompletion = true) {
var route = _step.value;
this.routes.push(route);
}
} catch (err) {
_didIteratorError = true;
_iteratorError = err;
} finally {
try {
if (!_iteratorNormalCompletion && _iterator.return) {
_iterator.return();
}
} finally {
if (_didIteratorError) {
throw _iteratorError;
}
}
}
};
这就是我所有的
推荐答案
未找到Symbol
的原因是因为它是在此处查看兼容性)
The reason why Symbol
is not found is because it is an ES6 feature that is not supported in your current Node.js build. Check to make sure your Node.js runtime is at least v4 (see compatibility here).
确保在Bluemix上构建的Node.js至少运行v4.0的简单方法是在应用程序的package.json
文件中定义engine
变量,如下所示:
The easy way to ensure your Node.js build on Bluemix is running at least v4.0 is to define your engine
variable in your app's package.json
file as such:
{ "engines" : { "node" : ">=4.0" } }
更新您的package.json
文件之后,将您的应用程序重新推送到Bluemix,它将使用您定义的Node.js版本进行构建
After updating your package.json
file, re-push your application to Bluemix and it will build it with your defined version of Node.js
