c++ - Qt Creator 拒绝将自定义 python 程序作为构建步骤命令执行

Question

我正在编写一个共享库，为了更新我的 /usr/include 目录中的头文件，我编写了一个 python 程序来比较和保留源目录中的头文件在 /usr/include 目录中更新，希望当我将它们与我的测试可执行文件链接时，在每个构建的 header 中自动完成。

问题是Qt Creator无法执行python程序。我的设置如下:

Command : 'python'
Working Directory : '/path/to/python/file'
Args    : 'PythonFile.py'

是的，已选中启用自定义流程步骤框。

我的输出类似于以下内容:

无法启动进程“python”PythonFile.py

诚然，如果有另一种更简单的方法来解决这个 header 问题(并且包括自动完成更新的能力)，我会洗耳恭听。

编辑

我还应该说我已经通过 CLI 执行了该程序并且它工作正常。

更新

根据 Slava 的建议更新命令，我得到以下输出:

Program is beginning
Traceback (most recent call last):
  File "UpdateHeaders.py", line 59, in <module>
    PROJECT_ROOT      = environ['ATLAS_PROJ_ROOT']
  File "/usr/lib/python2.7/UserDict.py", line 23, in __getitem__
    raise KeyError(key)
KeyError: 'ATLAS_PROJ_ROOT'
13:08:35: The process "/usr/bin/env" exited with code 1.

但是，如果我通过 CLI 运行它，我会得到:

Program is beginning

Copying "/home/amsterdam/Programming/atlas/Engine/AtlasEngine/Engine.hpp" to "/usr/include/atlas/Engine/Engine.hpp"

如图所示，除非通过 Qt Creator 运行，否则一切正常，没有任何错误。有什么建议吗？

命令:'/usr/bin/env'
工作目录:'/path/to/python/file'
参数:'python PythonFile.py'

或

命令:'/usr/bin/env'
参数:'python/path/to/python/file/PythonFile.py'
