我尝试使用 rbenv 的 ruby-build 插件构建 Ruby 3.2,但出现一些奇怪的编译错误:

Ruby 3.1 在同一台机器上构建没有任何问题。可能是什么问题?
问题是 centos7 附带的 GCC 太旧了。在我的情况下,机器上有
devtoolset-7-gcc.x86_64
软件包可用,因此我可以使用以下命令安装 Ruby 3.2:
CC=/opt/rh/devtoolset-7/root/usr/bin/gcc rbenv install 3.2.0 -v
希望这对某人有帮助。
我在 CentOS 7 和 ruby 3.1.4 上也遇到了这个问题,@tycoon 的解决方案也在这里提供了解决方案。为了更完整,我将添加以下内容:
# As root
yum install centos-release-scl-rh
yum install devtoolset-7-gcc-c++
# As deploying user
CC=/opt/rh/devtoolset-7/root/usr/bin/gcc rbenv install 3.1.4 -v
