那些遇到过的问题

在Mavericks上修复therubyracer/libv8(0.12.1)安装

Chr*_*s S 24 gcc rubygems v8 therubyracer libv8

好的,我正处于我的束缚之中.有一些类似的问题,但他们都提到了Therubyracer 0.10,他们大多认为问题可以通过升级到0.12来解决.

我有类似的问题,但是当我使用0.12时.

类似的问题

我在使用'标准'(xcode？)gcc以及来自自制软件的apple-gcc42和gcc时遇到了问题.我都试过--with-system-v8和--without-system-v8,并再次,没有骰子.

这是一些日志:

更糟糕的时候!

好.所以为了解决therubyracer 0.10的问题,有人推荐brew安装v8,然后告诉rubygems使用系统v8.让我们看看发生了什么!

完全挠我的头,已经浪费了几个小时.如果你能发现出了什么问题并帮助我修复它,你将永远成为我的英雄(ine).

Clo*_*ick 46

我可以在rm Gemfile.lock 尝试这个之后继续使用ruby racer ,这比RVM nuke选项更容易.

事先:我安装了v8 brew install v8,然后做了gem install libv8 -v '3.16.14.3' -- --with-system-v8

我正在跑10.10优胜美地

  • 我不得不'brew install v8`然后`bundle config build.libv8 - --with-system-v8`然后`bundle install` (7认同)
  • nooo,删除Gemfile.lock意味着更新所有宝石.如果你这样做,准备好大量测试. (2认同)

srt*_*t32 16

我能够通过跑步让事情再次发生gem install libv8 -v '3.16.14.3' -- --with-system-v8.

好的，现在已经解决了。

对于未来遇到同样问题的人来说，我正在为之前安装的 OS X 构建 ruby​​ 而苦恼。

通过完全核化 rvm 并从头开始修复，尽管我想你可以卸载/重新安装有问题的红宝石。
