无法安装pg gem

Question

我花了好几个小时试图找出它为什么不起作用后终于设法得到'pg'宝石安装...

最后我进入了sudo env ARCHFLAGS="-arch x86_64" gem install pg -v 0.12.2 -- --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config一个像魅力一样的工作.但是现在我尝试捆绑时仍然有同样的错误 - 所以我猜我没有真正解决问题？无论如何,这bundle install是在说什么:

我认为问题是bundler尝试使用另一个postresql安装(我已经删除)的pg_config来安装gem.有没有办法确保捆绑器使用正确的路径？

Answer 1

我被捆绑安装了3天.试着添加env ARCHFLAGS =" - arch x86_64"gem install pg - --with-pg-config =/usr/local/Cellar/postgresql/9.3.5_1/bin/pg_config

我能够看到pg gem在这个命令之后安装,但它仍然没有从bundle install安装,这很痛苦,因为我知道在Gemfile中写什么除了'宝石'pg'

最终对我有用的是找到我的pg_config在/Library/PostgreSQL/9.3/bin/pg_config中,默认情况下,Gemfile bundle install在/ usr/local/bin/pg_config中查找

我刚刚运行了以下命令并且发生了魔法.bundle config build.pg --with-pg-config =/Library/PostgreSQL/9.3/bin/pg_config
