我第一次尝试Gem 5，我使用X1 E0 F1 X作为指南。我有一个双 Boot 系统（Windows 11和Ubuntu 22. 04. 2），我在Ubuntu上这样做。
当我走到这一步

python3 `which scons` build/X86/gem5.opt -j9

我遇到一个错误，终止了建筑。

我搜索了一下，发现了一些关于链接到python目录和从CRLF和LF更改的东西，但我不知道发生了什么，我应该怎么做。
任何帮助都是感激的！

**更新：**Barmar是对的。我用了

dos2unix cpt_upgrader.py

而且已经修好了。但是我遇到了另一个问题：（

它说“native-elf-format.h”没有执行权限。当我给予权限时，它说：
