Ruby on rails 如何解决Curl:：Err:：ConnectionFailedError调用ruby的http_get方法？,ruby-on-rails,ruby,curl,libcurl,curb,Ruby On Rails,Ruby,Curl,Libcurl,Curb,当我调用http\u get方法时 Curl::Easy.http_get(url) 我有个例外 error='Curl::Err::ConnectionFailedError: Couldn't connect to server' duration=7805.63 view=0.00 db=1.33 remote_ip=127.0.0.1 Curl::Err::ConnectionFailedError - Couldn't connect to server: curb (0.

当我调用

http\u get

方法时

Curl::Easy.http_get(url)

我有个例外

error='Curl::Err::ConnectionFailedError: Couldn't connect to server' duration=7805.63 view=0.00 db=1.33 remote_ip=127.0.0.1

  Curl::Err::ConnectionFailedError - Couldn't connect to server:

这个问题只在我的系统中产生，在另一个系统上工作正常。我尝试了各种方法来解决这个问题，就像我用

ares

重建了

curl

，正如这个链接所建议的那样。我试图调试gem，但无法完全理解为什么会出现错误

这是curl版本的输出

$ curl --version
