在 Windows 上使用 scons 为 gem5 构建失败，并显示“No module named 'm5.util'”

编程问答 2022-05-31

问题描述

我想使用 gem5，为此，我遵循了一个教程，该教程让我下载 scons 并使用 python 安装它。 Scons 似乎可以独立工作。但是当我尝试执行此步骤时：

cd gem5
scons build/X86/gem5.opt -j <NUMBER OF cpus ON YOUR PLATFORM>

我收到此错误：

*** Error loading site_init file .\site_scons\site_init.py:
*** cannot import site init file .\site_scons\site_init.py:

我之前只有“m5”有一个错误，但我尝试安装它，现在我得到了“m5.util”错误。这可能是什么原因造成的，我该如何解决？ 编辑：我使用的是 Python 3.7.0

解决方法

我也遇到了这个问题。可能是因为我的源代码是从另一台计算机上复制过来的。

我的解决方案是 git clone gem5 源代码并再次编译。

git clone https://gem5.googlesource.com/public/gem5
# or
git clone https://github.com/gem5/gem5.git

再次编译，这次没有问题了。
