Rails Typhoeus卷曲故障

问题描述

我正在为这个错误而努力，因为类似的错误是指从源代码编译libcurl的实例.但是，我只是想让我的Ubuntu 12.04上运行一个以前的Rails项目.

I'm scratching my head on this error since similar errors refer to instances of compiling libcurl from source; however, I am just simply trying to get a former rails project running on my Ubuntu 12.04.

推荐答案

libcurl是否已正确安装? Typhoeus没有本机扩展，但是它需要libcurl动态库(.so)，因为它可以与 FFI库一起使用:

Is libcurl properly installed? Typhoeus has no native extensions but it requires libcurl dynamic library (.so) since it works with the FFI library:

# from lib/typhoeus/curl.rb
ffi_lib 'libcurl'

我会说不需要开发文件(标头)，所以sudo apt-get install libcurl3应该可以解决问题(否则，通过sudo apt-get install libcurl4-openssl-dev安装带有SSL支持的开发版本).

I would say that the development files (headers) are not needed so sudo apt-get install libcurl3 should do the trick (otherwise install the devel version w/ SSL support via sudo apt-get install libcurl4-openssl-dev).
