从源代码构建 V8
Building V8 from source
最近我尝试在 documentation, in order to use d8 本地的帮助下使用 gm 从源代码构建 V8 JavaScript 引擎；但是当我 运行 gm x64.release 命令时，它会引发以下异常。

值得一提的是，我使用 Ubuntu 18.04 作为我的操作系统。不知道是什么问题，怎么解决！
如有任何回应，我们将不胜感激...
编辑：当我运行命令使用python2（我的意思是python2 tools/dev/gm.py x64.release）时，它会导致一些其他问题，如下所示

gm.py 需要一个小的修复来与 Python 兼容 3. 我有一个补丁在某个地方，但还没有开始着陆...
同时，您可以在 Python 2 中手动 运行 它：
python2 tools/dev/gm.py
如果你没有python2命令，那么你必须为你的发行版安装相应的包。
据我所知，构建 V8 与 Python 3 不兼容，当我尝试使用 Python 3 构建它时出现了很多问题。最后我更改了默认版本Python 在我的 OS (Ubuntu 18.04) 到 Python 2 并且它非常有效。
起初我设置 Python 2 作为 Python 的替代：
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 1
然后我使用以下命令选择 python2 作为 Python 的默认版本：
sudo update-alternatives --config python

值得一提的是，我使用 Ubuntu 18.04 作为我的操作系统。不知道是什么问题，怎么解决！
如有任何回应，我们将不胜感激...
编辑：当我运行命令使用python2（我的意思是python2 tools/dev/gm.py x64.release）时，它会导致一些其他问题，如下所示

gm.py 需要一个小的修复来与 Python 兼容 3. 我有一个补丁在某个地方，但还没有开始着陆...
同时，您可以在 Python 2 中手动 运行 它：
python2 tools/dev/gm.py
如果你没有python2命令，那么你必须为你的发行版安装相应的包。
据我所知，构建 V8 与 Python 3 不兼容，当我尝试使用 Python 3 构建它时出现了很多问题。最后我更改了默认版本Python 在我的 OS (Ubuntu 18.04) 到 Python 2 并且它非常有效。
起初我设置 Python 2 作为 Python 的替代：
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 1
然后我使用以下命令选择 python2 作为 Python 的默认版本：
sudo update-alternatives --config python
