heroku pg:psql工作正常,但是当我迁移rake db:migrate时会收到需要安装pg客户端的错误.我需要在哪里安装pg客户端？任何帮助

Answer 1

在基于Debian的系统上,PostreSQL客户端程序由postgresql-client-common作为符号链接提供/usr/share/postgresql-common/pg_wrapper.

如果您安装该软件包并尝试使用任何PostgreSQL客户端程序(如psql,pg_dump,pg_dumpall和pg_restore),则pg_wrapper不会安装特定于版本的二进制软件包,例如postgresql-client-9.1,它将发出以下错误:

您必须至少安装一个postgresql-client- <version>包

解决此问题的最简单方法是安装postgresql-client元数据包.它总是依赖于基于Debian的系统上PostgreSQL当前支持的数据库客户端软件包,它依赖于postgresql-client-common

sudo apt-get install postgresql-client

同意所选择的答案，但我发现在 Ubuntu 18 上安装postgresql-client-12稍微复杂一些。

sudo apt update
sudo apt -y install vim bash-completion wget
sudo apt -y upgrade
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" | sudo tee /etc/apt/sources.list.d/pgdg.list
sudo apt update
sudo apt -y install postgresql-client-12

Answer 3

对于 Ubuntu 18.04.6 LTS，它仅适用于两个命令；

sudo apt-get install postgresql-client-common

和

sudo apt-get install postgresql-client
