Question

我正在尝试使用oct2py在简短的python脚本中重用一些八度的代码（在1 .m文件中）。 python脚本可从cmd控制台正常运行。我什至可以使用pyinstaller将其打包为exe文件（没有错误，只有几个警告），但是当我运行它时，可执行文件会抛出此错误并退出：

我已经安装了最新版本的python（3.7.1），oct2py（4.0.6），pyinstaller等

感觉就像我在丢失某物或不在此处某处连接某物一样，有人可以帮我解决这个问题吗？谢谢！

我遇到了同样的问题，正如DNR所说，我解决了设置OCTAVE_KERNEL_JSON变量的问题。为此：

在规范文件中将kernel.json文件添加为数据文件，这在此处https://pyinstaller.readthedocs.io/en/v3.4/spec-files.html#adding-files-to-the-bundle中进行了说明。

示例：

a = Analysis(...
     datas=[ ('/home/user/miniconda3/envs/env/lib/python3.8/site-packages/octave_kernel/kernel.json', 'octave_kernel') ],
     ...
     )

在导入oct2py之前，通过将其添加到我的代码中，将kernel.json的新路径分配给env变量

     if getattr(sys, 'frozen', False):
        application_path = sys._MEIPASS
        os.environ["OCTAVE_KERNEL_JSON"] = os.path.join(application_path, 'octave_kernel/kernel.json')

pyinstaller生成的可执行文件找不到octave_kernel \\ kernel.json
