【问题描述】：
我在尝试安装 ffi-yajl 时遇到以下错误
Using berkshelf 4.3.3
Installing ffi-yajl 2.4.0 with native extensions
STDERR: Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
Provided configuration options:

extconf.rb:9:in <main>': undefined method include_path' for Libyajl2:Module
(NoMethodError)
Did you mean? include
extconf failed, exit code 1
似乎是这条线失败了：
https://github.com/chef/ffi-yajl/blob/master/ext/ffi_yajl/ext/encoder/extconf.rb#L9
不幸的是，我对 Ruby 的了解非常有限，我不知道是否应该定义 'include_path' 以及是否应该定义它的原因。
谢谢
【问题讨论】：
-
你的操作系统是什么？，根据错误似乎你需要安装C编译器，检查你是否有gcc。该库是用 C 编写的 lloyd.github.io/yajl
-
我在树莓派上的 Debian Buster 上运行它。我很确定我有 gcc，但会检查。
