Rails Typhoeus 卷曲问题

Question

我对这个错误摸不着头脑，因为类似的错误是指从源代码编译 libcurl 的实例；但是，我只是想在我的 Ubuntu 12.04 上运行以前的 rails 项目。

感谢任何帮助或评论。

我尝试将 libcurl-devel 7.57.0-1 添加到 msys2（在 Windows 上），但没有帮助。 （pacman -Ss libcurl 显示已安装：

msys/libcurl 7.57.0-1 (libraries) [installed]
Multi-protocol file transfer library (runtime)
msys/libcurl-devel 7.57.0-1 (development) [installed]
Libcurl headers and libraries

因此，对于在 Windows 上遇到相同问题的任何人，绕过LoadError: Could not open library 'libcurl' 的简单方法是：

• 从此处找到的其中一个包https://curl.haxx.se/gknw.net/7.40.0/dist-w64/ 中获取libcurl.dll，并将其放在PATH 上。

  （我只是放在\ruby24\bin\下）

Answer 2

sudo apt-get install libcurl4-openssl-dev 为我工作。

Answer 3

是否正确安装了 libcurl？ Typhoeus 没有原生扩展，但它需要 libcurl 动态库 (.so)，因为它与 FFI library 一起使用：

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

我会说不需要开发文件（头文件），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 安装支持 SSL 的开发版本）。
