Postgres未安裝在Bundler中（Ruby on Rails）

Question

我變得非常絕望，我已經嘗試過有關該主題的所有答案，但似乎無濟於事。

錯誤日志如下所示：

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.
Results logged to /Users/kevinegstorf/.rvm/gems/ruby-2.0.0-p643/extensions/universal-darwin-14/2.0.0/pg-0.18.2/gem_make.out
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.

安裝gem install pg -v'0.18.2'會給我同樣的錯誤，希望有人可以幫助我。 TNX

Answer 1

如果您已經在Mac中安裝Postgres.app，則應將/Applications/Postgres.app/Contents/Version/9.4/bin/pg_config復制到另一個位置。 例如/home/pg_config

然后跑

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

Answer 2

您應該找到pg_config文件並將其添加到build命令中：

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

由於您的pg_config文件位於/ usr / local / bin / pg_config中，您是否嘗試過上面的命令（已編輯）？

如果這樣做沒有幫助，請嘗試：

env ARCHFLAGS="-arch x86_64" gem install pg
