我在 macOS 10.14.2 mojave 上，在我的 mysql 数据库上运行 rake db:setup 时出现错误。它在其他项目中工作正常，当我这样做时 gem list在其他项目中，他们都有 mysql 0.5.2 和 curb 0.9.7。我曾经遇到过相同的以下错误，除了它说的是 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 rake aborted!

最佳答案

跟随错误时:

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:

解决方法:

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 curb gem

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，尽管我使用以下命令禁用了它:

conda 配置 --set auto_activate_base false
