更新到Rails 3.1失败

我刚刚安装了带有Xcode 4.1的OS X Lion。我使用Ruby 1.9.2和宝石版本1.5.0。当试图从Rails 3.0.9升级到3.1时，出现以下错误：更新到Rails 3.1失败

有没有人知道这里发生了什么？

谢谢！

而不是做 “更新” 的，只是 “创业板安装导轨-v 3.1”

UPDATE： 显然轨3.1.0（activemodel的实际）取决于bcrypt-红宝石。 3.1.1中应删除此依赖关系（请参阅https://github.com/rails/rails/issues/2687）。

如果您不想等待，您需要解决bcrypt-ruby的构建问题。编译器错误提示ruby与编译器之间存在32位/ 64位不匹配。您是否将Lion安装在Leopard上？如果是这样，你可能不得不重建所有的rvm红宝石和本地扩展宝石。

即使您想等待，您可能应该重新编译，因为您可能会再次遇到此类编译器问题。作为测试，请尝试安装一个本地gem，如：“gem install eventmachine”。如果你得到相同的错误，这是一个很好的指标，每个本地宝石都会遇到这个问题。 http://jtigger-learning.wikidot.com/gem-install-fails-on-building-native-extensions

OP说，他得到了同样的错误：

的人谁在升级到雪豹，这个问题的解释类似的问题，请参见本页面。 –

@robert我没有看到OP提到的“gem install”。我只看到“宝石更新”。 – Kelvin

他发布了我删除的非答复。它所说的只是“试过了，并且得到了这个错误......”并且他复制了与上面在问题中看到的基本相同的文本。我会取消删除答案，以便您可以看到它。 –
