......

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:

Building native extensions.  This could take a while...
Successfully installed pg-0.18.4
Parsing documentation for pg-0.18.4
Done installing documentation for pg after 4 seconds

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 now enables -Werror=implicit-function-declaration by default:

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 explicit declaration when building C or Objective-C code for macOS (-Werror=implicit-function-declaration flag is on). This additional error detection unifies Clang’s behavior for iOS/tvOS and macOS 64-bit targets 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"
