本人小白,如果已经有人问过了这个问题,真的是不是我故意问的,是因为我无法通过本站的谷歌搜索。若有人问过了,××附上以前的问题链接××就行了。

it could not be located. please make sure you have a version of

need to special --with-v8-dir options if it is in a non-standard

extconf failed, exit code 1

没错,我是使用了系统自带的 libv8,这是因为如果不那样我安装 libv8 都要报错 错误就像上面那样: Failed to build gem native extension. 网上给的装上 libv8 的方法是加上 -- --with-system-v8 但是这明显指标不治本 求助呀,难道我要重装 rails 了么?

检查下 mkmf.log 错误报告,也可以去 stackoverflow 搜看看..
