psql: command not found

psql: command not found错误是因为系统无法找到psql命令所在的位置。解决该问题的方法是将PostgreSQL的bin目录添加到系统的环境变量中。
您可以按照以下步骤进行操作:
1. 确定PostgreSQL的安装位置,假设为/Library/PostgreSQL/13/bin。
2. 打开终端。
3. 输入以下命令并按Enter键:
export PATH="/Library/PostgreSQL/13/bin:$PATH"
这将将PostgreSQL的bin目录添加到环境变量中。
4. 现在,您应该能够在终端中成功执行psql命令了。
请注意,上述命令仅在当前终端会话中生效。如果您希望永久将PostgreSQL的bin目录添加到环境变量中,可以将上述命令添加到您的shell配置文件(例如~/.bashrc或~/.zshrc)中。

您需要安装PostgreSQL客户端工具psql。根据提供的引用,您可以使用以下命令在终端中安装psmisc和lsof:
```
yum install psmisc
yum install lsof -y
```
安装完成后,您可以使用以下命令安装PostgreSQL客户端工具psql:
```
yum install postgresql
```
如果您已经安装了PostgreSQL,但仍然收到“-bash: psql: command not found”错误消息,则可能需要将psql添加到系统路径中。您可以通过编辑.bashrc文件并将以下行添加到文件末尾来实现这一点:
```
export PATH=$PATH:/usr/pgsql-<version>/bin
```
请注意,您需要将<version>替换为您安装的PostgreSQL版本号。例如,如果您安装的是PostgreSQL 12,则应将<version>替换为12。完成后,请保存并关闭文件,然后重新启动终端窗口以使更改生效。
centos7 sudo: psql: command not found
The error "sudo: psql: command not found" indicates that the "psql" command is not available on your system or it is not in the system's PATH.
To resolve this issue, you can try installing the PostgreSQL client tools using your operating system's package manager. For example, on CentOS 7, you can run the following command to install the client tools:
```
sudo yum install postgresql
```
Once the installation is complete, you should be able to run the "psql" command with sudo privileges. If you still encounter the same error, you may need to add the PostgreSQL client tools directory to your system PATH.
On CentOS 7, you can do this by adding the following line to the end of your `~/.bashrc` file:
```
export PATH=$PATH:/usr/pgsql-<version>/bin
```
Replace `<version>` with the version number of PostgreSQL that you have installed. After saving the file, run `source ~/.bashrc` to reload the PATH configuration.
