Rails捆绑安装失败，因为“ byebug需要Ruby版本> = 2.0.0”

Question

I tried on ruby versions 2.0.0, 2.1.5 and 2.2.1 . Also gem install byebug -v '5.0.0' installs byebug succesfully. byebug -v returns: Running byebug 5.0.0, but bundle install still fails and gives me error "byebug requires ruby version >= 2.0.0".

Answer 1

我也碰巧发生了什么，对我有所帮助的是运行ruby -v并看到我的版本正确，然后运行捆绑更新并重新启动服务器，关闭所有选项卡，然后重新开始。

Answer 2

so, we can see through few possibilities, one is, there could be any predefined ruby declared inside your ruby app..check for it.. and change it. two... if you are using version manager like rvm then, check that you are using the current version more than 2.0.
