ESP32（Lilygo TTGO T-Display）烧写efuse设3.3V电压报错求助

我有一块Lilygo TTGO T-Display ESP32开发板，希望通过烧写内部efuse来选择电压区间，固定使用3.3V稳压输出。我已经完成了所有必要的下载和安装操作，但执行相关命令时出现问题：

执行第一条命令时的报错 #

执行命令：

python3 components/esptool_py/esptool/espefuse.py set_flash_voltage 3.3V

得到报错：

components/esptool_py/esptool/espefuse.py: line 7: import: command not found
components/esptool_py/esptool/espefuse.py: line 8: import: command not found
components/esptool_py/esptool/espefuse.py: line 11: syntax error near unexpected token `subprocess.run'
components/esptool_py/esptool/espefuse.py: line 11: `    sys.exit(subprocess.run([sys.executable, '-m', 'espefuse'] + sys.argv[1:]).returncode)'

执行第二条命令时的报错 #

执行命令：

python3 -m espefuse set_flash_voltage 3.3V 

得到报错：

我已经反复查阅文档并完成所有必要安装，请问操作哪里有误？
