An error occurred while installing ffi (1.12.2), and Bundler cannot continue.
Make sure that `gem install ffi -v '1.12.2' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
minimal-mistakes-jekyll was resolved to 4.18.1, which depends on
jekyll-feed was resolved to 0.13.0, which depends on
jekyll was resolved to 4.0.0, which depends on
jekyll-sass-converter was resolved to 2.1.0, which depends on
sassc was resolved to 2.2.1, which depends on
ffi
所以我试着按照它的建议去做：
$ gem install ffi -v '1.12.2' --source 'https://rubygems.org/'
Building native extensions. This could take a while...

“To see why this extension failed to compile”这句话听起来很有趣，但日志文件只包含：
pkg-config --exists libffi"
| pkg-config --libs libffi
=> "-lffi\n"
"gcc -o conftest -I/usr/local/rvm/rubies/ruby-2.6.0/include/ruby-2.6.0/i686-linux -I/usr/local/rvm/rubies/ruby-2.6.0/include/ruby-2.6.0/ruby/backward -I/usr/local/rvm/rubies/ruby-2.6.0/include/ruby-2.6.0 -I. -$
checked program was:
/* begin */
1: #include "ruby.h"
2:
3: int main(int argc, char **argv)
4: {
5: return 0;
6: }
/* end */
我已经安装了ruby-dev软件包。我不清楚它为什么会失败。
