【问题描述】：

我在 macOS 10.14.2 mojave 上运行 rake db:setup 在我的 mysql 数据库上时遇到错误。它在其他项目中运行良好，当我在其他项目中使用gem list 时，它们都有 mysql 0.5.2 和遏制 0.9.7。我曾经有同样的以下错误，除了它说 libssh2.1 而不是 libgssapi_krb5，所以我做了brew install libssh2 然后错误变成了这个。然后我尝试做brew install krb5，但这并没有什么不同。这是错误：

mbp-user:project user$ rake db:setup 耙中止！ LoadError：dlopen（/Users/user/.rvm/gems/ruby-2.5.3/gems/curb-0.9.7/lib/curb_core.bundle，9）：未加载库：@rpath/libgssapi_krb5.2.2.dylib 引用自：/Users/user/.rvm/gems/ruby-2.5.3/gems/curb-0.9.7/lib/curb_core.bundle 原因：找不到图像 - /Users/user/.rvm/gems/ruby-2.5.3/gems/curb-0.9.7/lib/curb_core.bundle /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:292:in require' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:292:inblock in require' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:258:in load_dependency' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:292:inrequire' /Users/user/.rvm/gems/ruby-2.5.3/gems/curb-0.9.7/lib/curl.rb:1:in <top (required)>' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:292:inrequire' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:292:in block in require' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:258:inload_dependency' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:292:in require' /Users/user/.rvm/gems/ruby-2.5.3/gems/curb-0.9.7/lib/curb.rb:1:in' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:292:in require' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:292:inblock in require' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:258:in load_dependency' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:292:inrequire' /Users/user/.rvm/gems/ruby-2.5.3/gems/user_client-3.7.0/lib/user_client/helpers/http_client.rb:1:in <top (required)>' /Users/user/.rvm/gems/ruby-2.5.3/gems/user_client-3.7.0/lib/user_client/helpers/authorized_request.rb:1:inrequire_relative' /Users/user/.rvm/gems/ruby-2.5.3/gems/user_client-3.7.0/lib/user_client/helpers/authorized_request.rb:1:in <top (required)>' /Users/user/.rvm/gems/ruby-2.5.3/gems/user_client-3.7.0/lib/user_client/adapter.rb:2:inrequire_relative' /Users/user/.rvm/gems/ruby-2.5.3/gems/user_client-3.7.0/lib/user_client/adapter.rb:2:in <top (required)>' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:292:inrequire' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:292:in block in require' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:258:inload_dependency' /Users/user/.rvm/gems/ruby-2.5.3/gems/activesupport-5.1.6/lib/active_support/dependencies.rb:292:in require' /Users/user/.rvm/gems/ruby-2.5.3/gems/user_client-3.7.0/lib/user_client.rb:2:in' /Users/user/work/angel/config/application.rb:7:in <top (required)>' /Users/user/work/angel/Rakefile:6:inrequire_relative' /Users/user/work/angel/Rakefile:6:in <top (required)>' /Users/user/.rvm/gems/ruby-2.5.3/gems/rake-12.3.1/exe/rake:27:in' /Users/user/.rvm/gems/ruby-2.5.3/bin/ruby_executable_hooks:24:in eval' /Users/user/.rvm/gems/ruby-2.5.3/bin/ruby_executable_hooks:24:in'

【问题讨论】：

您的问题解决了吗？我有完全相同的问题。你有安装 Xcode 命令行工具吗？
我最终只需要重新安装路边
@Rahul 你是如何重新安装它的？不适合我，我在莫哈韦也有同样的问题
nm，我在安装 gem 时手动更改了 LD/CPPFLAGS 以包含带有 '--with-ldflags=-LL/usr/local/opt/krb5/lib --with-cppflags=- 的 kerberos II/usr/local/opt/krb5/include' 并且成功了

【解决方案1】：

以下错误时：

rake db:drop

或

bundle exec rake db:drop

错误：

rake aborted!
LoadError: dlopen(/Users/afsan.abdulali.gujarati/.rvm/gems/ruby-2.4.6@introhive/gems/curb-0.9.10/lib/curb_core.bundle, 9): Library not loaded: @rpath/libgssapi_krb5.2.2.dylib
  Referenced from: /Users/afsan.abdulali.gujarati/.rvm/gems/ruby-2.4.6@introhive/gems/curb-0.9.10/lib/curb_core.bundle
  Reason: image not found - /Users/afsan.abdulali.gujarati/.rvm/gems/ruby-2.4.6@introhive/gems/curb-0.9.10/lib/curb_core.bundle
The thing that possibly fixed it:

解决方案：

brew install krb5

brew link --force krb5

可能会给出以下输出：

Warning: Refusing to link macOS-provided software: krb5
If you need to have krb5 first in your PATH run:
  echo 'export PATH="/usr/local/opt/krb5/bin:$PATH"' >> ~/.bash_profile
  echo 'export PATH="/usr/local/opt/krb5/sbin:$PATH"' >> ~/.bash_profile

For compilers to find krb5 you may need to set:
  export LDFLAGS="-L/usr/local/opt/krb5/lib"
  export CPPFLAGS="-I/usr/local/opt/krb5/include"

For pkg-config to find krb5 you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/krb5/lib/pkgconfig"

导出路径变量 LDFLAGS 和 CPPFLAGS

export LDFLAGS="-L/usr/local/opt/krb5/lib"
export CPPFLAGS="-I/usr/local/opt/krb5/include"

重新安装路边宝石

gem uninstall curb
gem install curb

关于我当前系统设置的附注：

Mac OS Catalina 10.15.3

我的系统上安装了 anaconda3，尽管我已使用以下命令禁用它：

conda config --set auto_activate_base false
