我正在尝试从 MAC 上的终端通过 ssh 进入服务器。几天前它还可以正常工作，但今天就停止了。
当我进入ssh username@server -i .ssh/file
我明白了-bash: ssh username@server -i: command not found
whereis ssh产生 /usr/bin/ssh
echo $PATH给我一个看起来很奇怪的路径 /Library/Frameworks/Python.framework/Versions/3.8/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin
我尝试将 PATH 设置为 /usr/bin，export PATH=/usr/bin并且似乎设置了它，但重新启动时它会重置为上述路径。
运行时 SSH 配置sudo nano /etc/ssh/ssh_config
GNU nano 2.0.6 File: /etc/ssh/ssh_config
# $OpenBSD: ssh_config,v 1.34 2019/02/04 02:39:42 dtucker Exp $
# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.
# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.
# Site-wide defaults for some commonly used options. For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.
最终对我有用的是以下命令：
/usr/local/Cellar/openssh/8.6p1/bin/ssh username@server -i .ssh/file
