python - 构建chrome时出错，subprocess.call抛出 "No such file or directory"

Question

Traceback (most recent call last):
  File "scripts/rule_bison.py", line 75, in <module>
    return Code = subprocess.call([bisonExe, '-d', '-p', prefix, inputFile, '-o', outputCpp])
  File "/usr/lib/python2.7/subprocess.py", line 493, in call
    return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

我正在尝试使用 ninja 构建 chromium 源代码。然后我得到了上面的错误。我不知道如何弄清楚。你能给我一些想法吗？

这意味着未找到由变量 bisonExe 命名的任何二进制文件。对于任何不存在的二进制文件，都会抛出 Errno 2 错误:

>>> subprocess.call(['spamandeggs', '-V'])
