Ruby on rails 钢轨s->；dyld:惰性符号绑定失败：找不到符号：\u rb\u intern2

所以rails s不能与rails generate一起工作。我以为问题出在heroku工具带上，所以我把它取了下来，但这并没有奏效。然后我检查了我的.zshrc文件，发现它在路径中调用了不同版本的ruby，所以我更新了它。然而，这并没有起作用。我没有主意了。有人能帮忙吗

如果您使用rvm，应该让它将其路径添加到$PATH，而不是自己添加。事实上，看起来您使用了rvm的一半：您正在选择为安装了rvm的ruby安装的gems，但是由于rvm ruby路径位于$PATH的末尾，因此运行

ruby

的ruby正在选择通过其他方法安装的ruby（可能是系统提供的方法）

因此，ruby 1.8.7试图加载为ruby 1.9.3编译的扩展，但该扩展不起作用

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

似乎有很多宝石

潜在的问题似乎是不兼容的C扩展库（在上面的例子中是sqlite3_native.bundle）。无论出于什么原因，gem似乎是为一个较旧版本的ruby安装的，而当前的ruby版本没有扩展库所寻找的导出C方法

有两种方法可以解决这个问题

• 卸载并重新安装该软件包（正如Shawn Balestracci在上面的评论中指出的）。在上述情况下，我们可以推断包是sqlite3：

  gem卸载{package}；gem安装{package}

或者（不太可取，但如果上述方法因某种原因失败，则可能有用）：

• 删除捆绑包文件并重新安装软件包。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{捆绑文件的路径}；gem安装{package}

更改C编译器对我很有用。我收到了其中一个关于gpgme gem的错误。我的gcc二进制文件指向我安装的gcc-4.9.2的安装。我将此更改为在Mac OS 10.10（Yosemite）上使用本机clang编译器，在卸载并重新安装gem后，rails服务器工作正常。

我在尝试运行

rails服务器时遇到了这个错误，但是，当我运行bundle exec rails server时，没有出现错误。
这是Ruby安装的问题，而不是实际页面的问题。我是如何解决的：

我在用RVM。首先，我将Ruby从2.1.1更新为2.2：

rvm install 2.2
rvm use 2.2

现在您必须重新安装所有gems：

gem install bundler
bundle install

下一次更新nginx.conf：

passenger_root /usr/local/opt/passenger/libexec/src/ruby_supportlib/phusion_passenger/locations.ini;
    passenger_ruby /Users/admin/.rvm/gems/ruby-2.2.4/wrappers/ruby;

您的这些值可能不同

然后重新启动Nginx。错误消失。
尝试重新加载rvm。然后尝试gem卸载sqlite3和gem安装sqlite3omfg！！！成功了！！！！非常感谢你，肖恩。如果可能的话，你能解释一下它为什么会起作用吗？rvm重新加载让你脱离了1/21.8.7/1.9.3状态（见张弗雷德里克的回答）。我不确定这是否损坏了sqlite3 gem安装，所以我让你重新安装它（这是给你带来错误的原因）。我最终再次收到错误，但我重新加载了rvm，之后效果很好。删除捆绑文件并重新安装包对我有帮助。非常感谢！我使用的外部gem（gemfile中的路径）是用不同版本的ruby编译的。这让我意识到了这一点。
