问题描述
在网站上，几乎所有API都显示此错误
In the website it is showing this error for almost all APIs
Failed to load resource: the server responded with a status of 502 (Proxy Error)
XMLHttpRequest cannot load. No 'Access-Control-Allow-Origin' header is present on the
requested resource. Origin is therefore not allowed access. The response had
HTTP status code 503.
注意::CORS已使用npm安装，但仍然出现上述错误.
NOTE:CORS has been already installed using npm but still getting the above error.
有时会收到此错误
Failed to load resource: net::ERR_INCOMPLETE_CHUNKED_ENCODING
使用rhc tail命令检查的日志位于日志下方
When checked log using rhc tail command got below log

我在哪里做错了?
推荐答案
我觉得您安装了错误的Ruby版本.我认为只有1.86至2.0版本有效.卸载Ruby，然后重新安装早期版本.
I have a feeling you have installed the wrong Ruby version. I think only version 1.86 thru 2.0 works. Uninstall Ruby and reinstall earlier version.
