# 错误重现
 执行pip3 list后出现
DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
# 解决方法
- 在 /etc下新建pip.conf:sudo nano /etc/pip.conf
- 写入[list] format=columnsctrl xY 保存
- 再次执行 pip3 lsit
