报错如下：

➜ poetry shell
➜ poetry run uvicorn main:app --reload --port 7000

(base)

解决方法：

1. 查看当前 poetry 命令路径：

➜ which poetry
/Users/guojianbo/.local/bin/poetry

2. 打开 /Users/guojianbo/.local/bin/poetry 文件

#!/bin/sh
'''exec' "/Users/guojianbo/Library/Application Support/pypoetry/venv/bin/python" "$0" "$@"
' '''
# -*- coding: utf-8 -*-
import re
import sys
from poetry.console.application import main
if __name__ == '__main__':sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])sys.exit(main())

看看报错信息可以发现是 /Users/guojianbo/Library/Application Support/pypoetry/venv/bin/python 路径的问题。

3. 查看你当前 python 的路径

➜ which python3
/Users/guojianbo/anaconda3/bin/python3

5. 将路径改成你当前使用 python 的路径

# 修改这一行即可
'''exec' "/Users/guojianbo/anaconda3/bin/python3" "$0" "$@" 
' '''
# -*- coding: utf-8 -*-
import re
import sys
from poetry.console.application import main
if __name__ == '__main__':sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])sys.exit(main())

再次运行 poetry run 命令, 可以看见成功运行了：
