将目标设置为构建Fuchsia时的TypeError

Question

尝试在构建Fuchsia之前设置目标，但得到以下错误。我尝试使用b.startswith(b'sep')将sep转换为字节，但它给出了错误。因此，我只是被困在如何处理这个问题上。我对python一窍不通。

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

输出结果为：

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的问题。问题可能来自于您的系统的python别名为python3而不是python2。

这是fuchsia构建脚本中的一个错误。可以通过以下任一方法解决此问题：

将文件的python解释器从from：#!/usr/bin/env python更新为#!/usr/bin/env python2

• Setting up您系统的python，使其指向python2。这可能会破坏您系统上的其他内容。
