如何解决如何解决在窗口中从源代码安装 V8 Build 的 depot 工具

我正在尝试从源代码构建 V8 以尝试一些事情。

最初，我遇到了 depot_tools 的一些问题，这使我找到了这个答案。 How do you compile V8 with Visual Studio?

但是，我收到了这个奇怪的 python 错误

Python path configuration:
  PYTHONHOME = 'D:\Code\v8/depot_tools/python276_bin'
  PYTHONPATH = 'D:\Code\v8/v8/build/gyp'
  program name = 'D:\Code\v8\depot_tools\bootstrap-3_8_0_chromium_8_bin\python3\bin\python3.exe'
  isolated = 0
  environment = 1
  user site = 1
  import site = 1
  sys._base_executable = 'D:\\Code\\v8\\depot_tools\\bootstrap-3_8_0_chromium_8_bin\\python3\\bin\\python3.exe'
  sys.base_prefix = 'D:\\Code\\v8/depot_tools/python276_bin'
  sys.base_exec_prefix = 'D:\\Code\\v8/depot_tools/python276_bin'
  sys.executable = 'D:\\Code\\v8\\depot_tools\\bootstrap-3_8_0_chromium_8_bin\\python3\\bin\\python3.exe'
  sys.prefix = 'D:\\Code\\v8/depot_tools/python276_bin'
  sys.exec_prefix = 'D:\\Code\\v8/depot_tools/python276_bin'
  sys.path = [
    'D:\\Code\\v8/v8/build/gyp','D:\\Code\\v8\\depot_tools\\bootstrap-3_8_0_chromium_8_bin\\python3\\bin\\python38.zip','D:\\Code\\v8/depot_tools/python276_bin\\DLLs','D:\\Code\\v8/depot_tools/python276_bin\\lib','D:\\Code\\v8\\depot_tools\\bootstrap-3_8_0_chromium_8_bin\\python3\\bin',]
Fatal Python error: init_fs_encoding: Failed to get the Python codec of the filesystem encoding

ModuleNotFoundError: No module named 'encodings'

我使用的 PYTHONHOME 环境有问题吗？我在 python276_bin 中找不到 depot_tools。

我从以下位置下载并复制到 depot_tools https://storage.googleapis.com/chrome-infra/python276_bin.zip

但是还是不行。但错误代码变为

Fatal Python error: init_fs_encoding: Failed to get the Python codec of the filesystem encoding
Python runtime state: core initialized
  File "D:\Code\v8\depot_tools\python276_bin\lib\encodings\__init__.py",line 123
