安装JSON gem的本机扩展错误

Question

我已经设置了Brightbox Ruby 2.1.0 apt包并遇到了本机编译错误安装json包.

$ sudo gem install json -v '1.8.1'

Fetching: json-1.8.1.gem (100%)
Building native extensions.  This could take a while...
ERROR:  Error installing json:
ERROR: Failed to build gem native extension.

    /usr/bin/ruby2.1 extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h

extconf failed, exit code 1

我已ruby2.0-dev按照此处的说明安装,但它将标头放在不同的文件夹中(/usr/include/ruby-2.0.0/ruby,将它们复制到/ usr/lib/ruby​​/include没有用).知道如何安装这个宝石吗？

Answer 1

我想你需要安装ruby2.1-dev软件包,而不是ruby2.0-dev,如果你使用的是Ruby 2.1.我没有使用过Brightbox软件包,所以我只是猜测我很害怕.
