我以为我没有在我的计算机上安装PostgreSQL,因此下载它没用。 我尝试了其他几个选项,并再次使用类似错误运行以下命令。
gem install pg
答案 0 :(得分:9)
找到了这个东西。
因为我已经安装了PostgreSQL.app。给出以下命令 -
gem install pg -- --with-pg-config=/Applications/Postgres93.app/Contents/MacOS/bin/pg_config
答案 1 :(得分:1)
你有postgres开发库吗?
答案 2 :(得分:1)
我卸载然后重新安装了postgresql。然后我安装了pg -v'0.17.1'。之后我跑了捆绑。它奏效了。
