无法启动KivyMD-终端问题

Question

我已经安装KivyMD并在python3上运行setup.py。但是，我已经

Traceback (most recent call last):
  File "/Users/myname/KivyMD/setup.py", line 64, in <module>
    write_version_info()
  File "/Users/myname/KivyMD/setup.py", line 59, in write_version_info
    open(filename, "wt", encoding="utf-8").write(version_info)
PermissionError: [Errno 13] Permission denied: '/Users/myname/KivyMD/kivymd/_version.py'

这是什么意思，我该如何授予许可？这与防病毒软件有关吗？
