python3 在linux 绝对路径无法运行,子目录是可以运行

Question

linux 系统下面 绝对路径运行脚本找不到pip3 安装的依赖包
命令如下

/usr/bin/python3 /root/douyin/DYSECOO/msg_test.py

报错如下

Traceback (most recent call last):
  File "/root/douyin/DYSECOO/msg_test.py", line 6, in <module>
    from google.protobuf import json_format
ModuleNotFoundError: No module named 'google
``
pip3 是在/usr/local/bin  目录

root@center1:/usr/local/bin# ls
2to3 chardetect easy_install-2.7 idle3 pip pip3.7 pydoc3.7 python3.7 python3.7m python3-config pyvenv-3.7
