An error occurred while installing pg (0.18.4), and Bundler cannot continue.
Make sure that `gem install pg -v '0.18.4'` succeeds before bundling.
运行 'gem install pg -v '0.18.4' 结果:
Running 'gem install pg -v '0.18.4' results in:

然而，再次运行捆绑安装"失败.有什么建议么?我试过用自制软件卸载并重新安装 postgresql，但没有运气
Yet running 'bundle install' again fails. Any suggestions? I've tried uninstalling and reinstalling postgresql with homebrew with no luck
推荐答案
我现在在 macOS Catalina 上遇到了类似的错误，但我无法成功运行
I have got a similar error now on macOS Catalina, but I was not able to successfully run
gem install pg -v '0.18.4'
我在帮助我解决问题的 puma gem(我知道这是另一个 gem)中发现了这个问题:https://github.com/puma/puma/issues/2304.
I found this issue in the puma gem (I know this is another gem) that helped me solve the issue: https://github.com/puma/puma/issues/2304.
在那里，我发现了这个:
There, I found this:
Clang 现在默认启用 -Werror=implicit-function-declaration:
Clang 现在在您使用没有显式的函数时报告错误为 macOS 构建 C 或 Objective-C 代码时的声明(-Werror=implicit-function-declaration 标志打开).这个额外的错误检测统一了 iOS/tvOS 和 macOS 64 位的 Clang 行为此诊断的目标.(49917738)
Clang now reports an error when you use a function without an explicitdeclaration when building C or Objective-C code for macOS(-Werror=implicit-function-declaration flag is on). This additionalerror detection unifies Clang’s behavior for iOS/tvOS and macOS 64-bittargets for this diagnostic. (49917738)
还有这个:
gem install puma:4.3.5 -- --with-cflags="-Wno-error=implicit-function-declaration"
因此，我能够使用以下命令构建 pg:
So, I was able to build pg with:
gem install pg -v '0.18.1' -- --with-cflags="-Wno-error=implicit-function-declaration"
