我沒有永久解決它,但我找到了一個解決方案來規避錯誤。 當我給一個新的軌道,它生成的寶石文件中,將指定的軌道版本,我只是改變了產生的Gemfile,我「創造」的一個:
source 'https://rubygems.org'
gem 'openssl', '2.0.4'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', github: 'rails/rails', branch: '4-2-stable'

gem 'sass-rails', '~> 5.0'

gem 'byebug'
end

end
我不能使用rbenv也不rvm升級我的導軌,所以我做這個「調整」。
'rails g scaffold用戶名電子郵件'適用於我。然而,這個警告意味着你正在運行帶有舊版Rails的Ruby的最新版本。升級Rails(或降級Ruby)可以解決這個問題。 – Stefan
我該怎麼做?我已經嘗試過原始文檔,但我不知道該怎麼做......我不明白該怎麼做。 –
我認爲值得讓Rbenv(我使用這個)或rvm(我在MacOSX上遇到了幾個與rvm相關的問題),以便管理你的ruby的東西。它們允許下載和安裝ruby版本,爲某些項目設置「全局」ruby版本和gem set,和/或本地ruby版本以及所需的gemset。我發現它安裝和使用非常緊張。 –
