[英]Meteor Error: A method named insert is already defined
I had created a mongo collection named votes
Which was working properly even after updating the packages to latest meteor version. 我创建了一个名为votes
的mongo集合,即使在将软件包更新到最新的流星版本之后也能正常工作。 I don't remember changing any part of the working code however I am getting this errors. 我不记得改变了工作代码的任何部分但是我得到了这个错误。 I had updated the project using meteor update
command and tested it right after the update. 我使用meteor update
命令更新了项目,并在更新后立即对其进行了测试。 It ran successfully that time but I have no clue why I'm getting this error. 它成功地运行了,但我不知道为什么我得到这个错误。 And, not sure which source file should I add to get help... 而且,不确定我应该添加哪个源文件来获取帮助...
Can anyone shed some light? 任何人都能解释一下吗?

Please note: If you are currently using the Angular-Meteor tutorial to build the app Socially and you are using an integrated development environment (IDE) like WebStorm , which is able to automatically compile TypeScript to JavaScript, my answer will probably help you to solve this problem. 请注意:如果您当前使用的角流星 教程构建应用程序在社交场合 ,你使用的是集成开发环境(IDE),如WebStorm ,它能够自动编译打字稿为JavaScript,我的回答可能会帮你解决这个问题。
I received this error without redefining a collection. 我没有重新定义集合就收到了这个错误。 Later I found out that my IDE (WebStorm 2016.1) caused duplicates, because it automatically compiled TypeScript to JavaScript even though Meteor handles this job for us. 后来我发现我的IDE(WebStorm 2016.1)导致重复,因为它自动将TypeScript编译为JavaScript,即使Meteor为我们处理这项工作。 Luckily I got rid of this error by just disabling the TypeScript Compiler in WebStorm and deleting the compiler output files. 幸运的是,通过在WebStorm中禁用TypeScript编译器并删除编译器输出文件,我摆脱了这个错误。
So, if WebStorm asks you if you want to compile TypeScript to JavaScript, say No ! 因此,如果WebStorm询问您是否要将TypeScript编译为JavaScript,请说“ 不” !
If you have already messed up your setup, go to WebStorm → Preferences → Languages & Frameworks → TypeScript and uncheck the "Enable TypeScript Compiler" option: 如果您已经搞砸了设置,请转到WebStorm → 首选项 → 语言和框架 → TypeScript,然后取消选中“启用TypeScript编译器”选项:
After that, delete the TypeScript compiler output files: 之后,删除TypeScript编译器输出文件:
Now your application should work again. 现在您的应用程序应该再次运行 Happy coding! 快乐的编码!
your xyz.js file code is 你的xyz.js文件代码是
console.log("This is test panel ....");
new Mongo.Collection('players'); <<-------remove This line
PlayersList = new Mongo.Collection('players');
remove 去掉
new Mongo.Collection('players');
I had this error because I had new'd the same mongo collection into two different variables. 我有这个错误,因为我将同一个mongo集合新增为两个不同的变量。
eg 例如
CrowdEstimates = new Mongo.Collection('crowdEstimates');
CrowdEstimateAggregations = new Mongo.Collection('crowdEstimates');
Cut and paste and distraction.... 剪切和粘贴和分心....
我认为你在app/collections/collection.js
方法名称相同
I encountered the same error message, it happened after I reorganized the folder structure of my application. 我遇到了相同的错误消息,它发生在我重新组织我的应用程序的文件夹结构后。 I had a collection Javascript named drivers.js
in a folder named both
and I had another Javascript file with the same name (and code) in both\\collections\\drivers.js
. 我在一个名为both
的文件夹中有一个名为drivers.js
的集合Javascript,我在both\\collections\\drivers.js
有另一个具有相同名称(和代码)的Javascript文件。
So the error message is more-or-less correct. 因此错误消息或多或少是正确的。 Just weird looking, at least on my system. 看起来很奇怪,至少在我的系统上。
