背景：

Run arc diff --preview to create code revision on remote terminal, but exception happened.

nn@hhh:~/ppp$ arc diff --preview
Linting...
 Exception
Error in parsing '.arclint' file, in key 'bin' for linter 'pylint'.
None of the configured binaries can be located.
(Run with `--trace` for a full exception trace.)

排查：

1、检查pylint 是否安装。确认安装

pip3 show pylint

2、--trace 查看full exception trace.

发现arc 帮我们执行检查命令which 'pylint'时，抛出异常

 

3、确认pylint是否能直接引用到

本地：ubuntu本地执行which 'pylint' 无报错，且尝试本地执行arc lint 也不报错

远程：remote terminal 运行，cmd not found

4、修改环境变量，将$HOME/.local/bin 添加到PATH 中

5、运行arc link 和 arc diff --preview, 执行成功
