Question

我变得非常绝望，我已经尝试了关于这个主题的每个答案，但似乎没有任何效果。

错误日志如下所示：

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/kevinegstorf/.rvm/gems/ruby-2.0.0-p643/gems/pg-0.18.2 for inspection.

An error occurred while installing pg (0.18.2), and Bundler cannot continue.
Make sure that `gem install pg -v '0.18.2'` succeeds before bundling.

安装gem install pg -v＆＃39; 0.18.2＆＃39;给了我同样的错误我希望有一个人可以帮助我。 TNX

如果您已在Mac中安装Postgres.app，你应该将/Applications/Postgres.app/Contents/Version/9.4/bin/pg_config复制到另一个地方。例如/home/pg_config

然后运行

bundle config build.pg --with-pg-config=/home/pg_config
bundle install

Answer 2

您应该找到pg_config文件并将其添加到build命令：

bundle config build.pg --with-pg-config=/usr/local/bin/pg_config

由于你的pg_config文件位于/ usr / local / bin / pg_config你是否尝试过上面的命令（已编辑）？

如果这没有帮助，可以尝试：

env ARCHFLAGS="-arch x86_64" gem install pg

Postgres没有在Bundler中安装（Ruby on Rails）
