Ruby on rails Ruby gem“byebug 5.0.0”安装失败，原因是出现错误

我正试图在ubuntu环境中安装byebug gem v5.0.0。 V5.0.0是项目要求，我不能使用更新的版本。 这些是我正在使用的当前版本

bundle -v
Bundler version 2.1.4

ruby -v
ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux-gnu]

bundle -v
Bundler version 2.1.4

rvm -v
rvm 1.29.10 (manual) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]

rails -v
Rails 5.2.3

当我尝试使用gem install byebug-v 5.0.0进行安装时，以下内容将写入cli。 执行gem的make文件时，安装似乎失败

即使我尝试在/var/lib/gems/2.7.0/gems/byebug-5.0.0/ext/byebug目录中执行make，我也会从context.c文件开始收到相同的错误消息

这似乎是5.0.0版本的安装问题，我确实尝试安装了最新版本的byebug进行测试，并且安装成功

该版本的byebug是2015年ruby在v2.2.1上发布的

如果你不能使用更新的bye bug；使用旧的ruby

ruby的旧版本可能会要求您使用项目所需的所有gems的旧版本。是否有显示目标版本的Gemfile.lock？如果不是的话，您可能不得不在2015年初使用ruby gems来查找每一代的最新版本
