AWS CodeDeploy失败，因为找不到python3命令

Question

我已将AWS CodeDeploy连接到github。没有代码构建。CodeDeploy在安装前步骤中失败

appspec.yml

version: 0.0
os: linux
hooks:
  BeforeInstall:
    - location: scripts/RunMyBot.sh
      timeout: 300
      runas: root

RunMybot.sh

#!bin/bash

sudo python3 -m pip install --user --upgrade pip
pip3 install -r requirements.txt
python3 ./botMain.py

错误日志：
