尝试在构建 Fuchsia 之前设置目标，但出现以下错误。我尝试sep通过使用将其转换为字节，b.startswith(b'sep')然后它给出了错误。所以我只是坚持如何处理这个问题。我对python的了解为零。

prashant@prashant-Lenovo:~/fuchsia$ scripts/fx set x64

输出是：

ERROR at //build/gn/BUILD.gn:67:5: Script returned non-zero exit code.
    exec_script("//build/zircon/list_source_files.py", [], "list lines")
    ^---------- Current dir: /home/prashant/fuchsia/out/x64/ Command: /usr/bin/env -- /home/prashant/fuchsia/build/zircon/list_source_files.py Returned 1. stderr:

我也遇到了这个特殊问题。问题可能来自您的系统的python别名为python3而不是python2.

这是紫红色构建脚本中的一个错误。可以通过以下任一方式解决：

  • 将文件的 python 解释器从 from: 更新#!/usr/bin/env python为#!/usr/bin/env python2
  • 将系统设置python为指向python2. 这可能会破坏您系统上的其他内容。
