rails s - > dyld:懒符号绑定失败:未找到符号:_rb_intern2

Question

因此导轨不会与导轨生成一起工作.我认为问题是heroku toolbelt,所以我删除了它,但是没有做到这一点.然后我检查了我的.zshrc文件,看到它有一个不同版本的ruby,它在PATH中调用,所以我更新了.然而,这没有做到.我没有想法.有人可以帮帮忙吗？

Answer 1

类似的错误形式:

Symbol not found: {some-symbol}
Referenced from: /path/to/some/file.bundle
Expected in: flat namespace

似乎突然出现了很多宝石.

底层问题似乎是一个不兼容的C扩展库(在上面的例子中,sqlite3_native.bundle).似乎无论出于何种原因,gem都安装了旧版本的ruby,而当前的ruby版本没有扩展库正在寻找的导出C方法.

有两种方法可以解决这个问题

• 卸载并重新安装软件包(如上面Shawn Balestracci的评论中所述).在上面的例子中,我们可以推断出包是sqlite3:

  gem uninstall {package}; gem install {package}

或者(不太可取,但如果上述方法由于某种原因失败,则可能有用):

• 删除捆绑包文件并重新安装包.查看错误消息:引用自:/Users/admin/.rvm/gems/ruby-1.9.3-p392/gems/sqlite3-1.3.7/lib/sqlite3/sqlite3_native.bundle,我们只需要:

  rm {path-to-bundle-file}; gem install {package}

Answer 2

如果你使用rvm,你应该让它将路径添加到$ PATH而不是自己动手.事实上,看起来你有一半使用rvm:你正在为rvm安装的ruby安装宝石,但由于rvm ruby​​路径在$ PATH运行结束时正在ruby通过一些安装来获取ruby其他方法(也许系统提供一个)

因此,你有ruby 1.8.7试图加载为ruby 1.9.3编译的扩展,这不起作用
