Can't install a gem on CentOS 8
使用root用户安装rubygems.
# yum install rubygems -y
查看ruby的版本时,得到
# ruby -v
ruby 2.5.9p229 (2021-04-05 revision 67939) [x86_64-linux]
Gem的版本:
# gem -v
2.7.6.3
安装gem时,得到
# gem install fluent-plugin-kinesis

我应该安装高版本ruby吗?这是系统默认的。
更新
我安装了ruby-devel
# yum install ruby-devel.x86_64
运行再次安装fluent-plugin-kinesis
gem

看看docs or this answer。
Install Ruby >= 2.4 on your local environment. In addition, install ruby-dev package via Package Manager to build native extension gems.
我相信 CentOS ruby-dev
相当于 ruby-devel
。您可以通过 运行 yum search ruby-dev
确认
您会找到 2 个包,一个 i686
和另一个 x86_64
。您可以通过 运行 lscpu | grep Arch
.
找到您需要的那个
然后只需下载包,然后重新运行gem install
