在我的 ubuntu 中添加 python2.7 后 gem5 编译出现问题

我最初有 python3.8，并成功编译了 gem5 (X86 和 ARM)。然后我添加了 python2.7 来运行一些模型。现在，当我尝试使用以下命令编译 gem5 时，出现了之前没有出现过的错误：

scons build/ARM/gem5.opt

scons build/X86/gem5.opt

错误是：

Checking for compiler -Wno-self-assign-overloaded support... (cached) yes
AttributeError: Flag Checkpoint already specified:
  File "/home/ahmed/gem5/SConstruct", line 731:
    SConscript('src/SConscript', variant_dir=variant_path, exports=exports)
  File "/usr/lib/scons/SCons/Script/SConscript.py", line 660:
    return method(*args, **kw)
  File "/usr/lib/scons/SCons/Script/SConscript.py", line 597:
    return _SConscript(self.fs, *files, **subst_kw)
  File "/usr/lib/scons/SCons/Script/SConscript.py", line 286:

  File "/home/ahmed/gem5/build/ARM/SConscript", line 400:

是不是因为添加了额外的 Python 版本？有什么解决办法吗？
