当我跑步时
env ARCHFLAGS="-arch x86_64" gem install pg
根据这，我得到

Can't find the PostgreSQL client library (libpq)
*****************************************************************************
Unable to find PostgreSQL client library.
Please install libpq or postgresql client package like so:
sudo apt install libpq-dev
sudo yum install postgresql-devel
sudo zypper in postgresql-devel
sudo pacman -S postgresql-libs
or try again with:
gem install pg -- --with-pg-config=/path/to/pg_config
or set library paths manually with:
gem install pg -- --with-pg-include=/path/to/libpq-fe.h/ --with-pg-lib=/path/to/libpq.so/

我也做过yum groupinstall 'Development Tools'
我应该怎么做才能安装 pg gem？
答案1
就我而言（Centos 7）需要pg_config，所以我安装了开发包：
yum install postgresql-devel
然后我必须将其添加到路径中
export PATH=$PATH:/usr/pgsql-12/bin
我使用的是 pgsql 12，您可能需要指向您的版本文件夹。
