我在尝试安装byebug时遇到错误。 这是什么原因?
sudo gem install byebug -v '10.0.1'
Building native extensions. This could take a while...

告诉您无法找到构建gem所需的头文件。
另外,为什么要安装sudo
?你在用什么系统?您使用的是版本管理器rvm
还是rbenv
?我推荐https://rvm.io/rvm/install
尝试使用系统库安装
gem install byebug -v '10.0.1' --use-system-libraries
如果不起作用,请运行以下命令并发布其输出:
which ruby
ruby -v
gem -v
echo "${PATH//:/\n}" #may not work if your not on an *nix system
更新:
转到项目的根目录。选择一个ruby版本,但看起来ruby指向系统ruby,而不是rvm版本。尝试安装新的红宝石:
rvm install 2.4.1
rvm use 2.4.1
gem install byebug
如果您的项目中有Gemfile,并且它有ruby -v
,请确保它与您使用rvm设置的版本相匹配,并将gem 'byebug'
添加到您的Gemfile,然后运行
bundle install
