Rails Typhoeus卷曲麻烦

Question

我对这个错误感到头疼,因为类似的错误指的是从源代码编译libcurl的实例; 但是,我只是想在我的Ubuntu 12.04上运行一个以前的rails项目.

libcurl是否正确安装？Typhoeus没有原生扩展,但它需要libcurl动态库(.so),因为它适用于FFI库:

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

我会说开发文件(标题)不是必需的,所以sudo apt-get install libcurl3应该这样做(否则安装devel版本w/SSL支持通过sudo apt-get install libcurl4-openssl-dev).
