Ruby 1.9.2和Rails 3无法打开Rails控制台

[gkaykck@main myApplication]$ rails console

我已经在ruby 1.9.2p136上安装了rails 3,我想是可以的。但是我无法启动Rails控制台,它给了我我复制的错误。该应用程序在ruby

1.8.7上运行良好,并且我从未见过这样的错误。

有什么想法吗?

回答:

显然,ubuntu和ruby并不总是像应该的那样捕获依赖项。

在第一个Google匹配中(是的,我在检查第一个结果之前单击了#2处的堆栈溢出)。

导航到Ruby源,然后输入:

sudo apt-get install libreadline5-dev

cd ext/readline

ruby extconf.rb

make

sudo make install

因此,如果您在其他发行版上,请确保以某种方式安装readline(源代码/程序包),然后从源代码在extconf上运行make /

install。我尝试了gkaykck的建议,但是在我的系统上已经没有readline了。

$ ruby extconf.rb

checking for tgetnum() in -lncurses... no

checking for tgetnum() in -ltermcap... no

checking for tgetnum() in -lcurses... no

checking for readline/readline.h... no

checking for editline/readline.h... no
