Rails設置; rails server命令無法正常工作

Question

我是RoR的新手，當我去嘗試rails server命令時，我得到了這個奇怪的錯誤信息：

任何人都可以幫忙嗎？

Answer 1

它看起來像sqlite3 ruby​​ gem有一些麻煩。

首先，確保安裝了libsqlite3開發包。

在debian派生詞上，這看起來像

sudo apt-get install libsqlite3-dev

然后，安裝寶石

gem install sqlite3

在普通的rails設置中，應該通過Gemfile設置bundler來為你安裝所有必需的gem。

bundle install

Answer 2

在您的應用程序中安裝gem sqlite，然后重試。

Answer 3

重新安裝導軌。 你有兩個不同版本的紅寶石嗎？

請使用更新最新的Ruby-gems

gem update

我建議你使用下面的命令重新安裝rails，

 gem install rails
