Rails返回:[BUG]分段错误

Question

如果我跑rails s,我得到:

/Users/adam/.rvm/gems/ruby-1.9.3-p327/gems/pg-0.13.2/lib/pg_ext.bundle: [BUG] Segmentation fault
ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]

Abort trap: 6

版本:

rails -v
Rails 3.2.1
ruby -v
ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-darwin12.2.0]

如果我使用1.9.3,为什么在错误消息中提到了ruby版本1.8.7？

Answer 1

最初安装它时,看起来你的pg gem是针对Ruby 1.8.7编译的.简单地运行gem uninstall pg; gem install pg应该重新编译它对Ruby 1.9.3.

如果你还没有,我建议使用RVM来避免这种问题.

我遇到了类似的问题，运行任何命令都会bundle exec出现分段错误：

~/mayapp >bundle exec rake -T
/Users/rogermarlow/.rvm/gems/ruby-1.9.3-p327/gems/mysql2-0.3.11/lib/mysql2/mysql2.bundle: [BUG] Segmentation fault
ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin11.0]

Abort trap: 6

我遇到了两个问题（1）使用 1.9.3p327 而不是 1.9.3p125 和（2）GEM_HOME 环境变量指向现在不存在的目录。所以我的解决办法是：

~/myapp >rvm list

rvm rubies

=* ruby-1.9.3-p327 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

~/myapp >rvm install 1.9.3-p125
**snip**
~/myapp >rvm use 1.9.3-p125
Using /Users/rogermarlow/.rvm/gems/ruby-1.9.3-p125
Running /Users/rogermarlow/.rvm/hooks/after_use_maglev
~/myapp >echo $GEM_HOME
/Users/rogermarlow/.rvm/gems/ruby-1.9.3-p125
~/myapp ># you should check that the directory in $GEM_HOME exists, I had ...-p125@global which had been removed at some point
~/myapp >bundle install
**snip**

现在尝试一下bundle exec分段错误......

~/myapp >bundle exec rake -T
rake about                  # List versions of all Rails frameworks and the environment
rake assets:clean           # Remove compiled assets
rake assets:precompile      # Compile all the assets named in config.assets.precompile
