Gem files will remain installed in /Users/marklalich/.bundler/tmp/14076/gems/pg-0.17.1 for inspection.

An error occurred while installing pg (0.17.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.17.1'` succeeds before bundling.

我在网上找不到任何东西，请有人帮忙！

谢谢！！

Answer 1

我有同样的问题，我的修复是先设置捆绑配置设置：

bundle config build.pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.3/bin/pg_config

不要挂在pg宝石上。 执行此捆绑包配置后执行捆绑安装修复了“make failed”问题。

作为参考，这是帮助https://stackoverflow.com/a/9235107/3546680的答案，但它是user944938的答案给了我正确的路径。感谢并希望它也帮助其他人！

你是怎么安装postgres的。 您可以使用postgresapp.com上的postgres应用安装postgres。 将其放入应用程序目录并配置pg gem的路径。 gem install pg - --with-pg-config = / Applications / Postgres.app / Contents / Versions / 9.3 / bin / pg_config
