我正在尝试在 Ubuntu 22.04 ARM64 上构建 V8。我尝试过通过方便的脚本进行构建，即

然后我尝试构建/使用与
fetch v8export VPYTHON_BYPASS="manually managed python not supported by chrome operations"Building final compiler.
Traceback (most recent call last):
File "/home/v8user/Desktop/v8/tools/clang/scripts/get_tensorflow.py", line 178, in <module>
print(os.path.dirname(spec.origin))
AttributeError: 'NoneType' object has no attribute 'origin'

raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '['vpython3', '/home/v8user/Desktop/v8/tools/clang/scripts/get_tensorflow.py']' returned non-zero exit status 1.
然后我尝试了以下最近的方法：
克隆 V8 存储库： 使用 Git 克隆 V8 存储库：
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH=$PATH:/home/v8user/Desktop/depot_tools
fetch v8
绕过VPYTHON：通过设置环境变量绕过
vpythonexport VPYTHON_BYPASS="manually managed python not supported by chrome operations"
设置 GN 参数： 为所需配置手动设置 GN 参数：
gn args out.gn/arm64.release
在打开的编辑器中，我粘贴以下内容以进行发布版本：
is_debug=false
target_cpu="arm64"
v8_target_cpu="arm64"
is_clang=false
treat_warnings_as_errors=false
use_custom_libcxx=false
use_custom_libcxx_for_host=false
随后：
ninja -C out.gn/arm64.release
这至少开始构建，但是构建以以下方式终止：
ninja: Entering directory `out.gn/arm64.release'
