ruby-on-rails - rails s -> dyld : lazy symbol binding failed: Symbol not found: _rb_intern2

Question

所以 rails s 不能与 rails generate 一起工作。我认为问题出在 heroku 工具带上，所以我删除了它，但这并没有解决问题。然后我检查了我的 .zshrc 文件，发现它在 PATH 中调用了不同版本的 ruby​​，所以我更新了它。然而这并没有做到。我没主意了。有人可以帮忙吗？

表格的类似错误:

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

似乎出现了很多 gem 。

根本问题似乎是一个不兼容的 C 扩展库(在上述情况下，sqlite3_native.bundle)。似乎无论出于何种原因，gem 是为旧版本的 ruby​​ 安装的，而当前的 ruby​​ 版本没有扩展库正在寻找的导出 C 方法。

有2种方法可以解决这个问题

卸载并重新安装软件包(正如上面 Shawn Balesstracci 的评论中所指出的)。在上述情况下，我们可以推断该包是 sqlite3:
gem uninstall {package}; gem install {package}

或(不太可取，但如果上述方法由于某种原因失败，可能会有用):

删除捆绑文件并重新安装包。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}
