我正在尝试在使用 oct2py 的简短 python 脚本中重用一些八度音程代码（在 1 .m 文件中）。python 脚本从 cmd 控制台正确运行。我什至可以使用 pyinstaller 将它打包成一个 exe（没有错误，只有几个警告），但是当我运行它时，可执行文件会抛出这个错误并退出：

我安装了最新版本的python(3.7.1)、oct2py(4.0.6)、pyinstaller等

感觉就像我错过了一些东西或没有在这里连接一些东西，有人可以帮我解决吗？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。要做到这一点：

  1. 在规范文件中添加 kernel.json 文件作为数据文件，此处解释为https://pyinstaller.readthedocs.io/en/v3.4/spec-files.html#adding-files-to-the-bundle。

例子：

a = Analysis(...
     datas=[ ('/home/user/miniconda3/envs/env/lib/python3.8/site-packages/octave_kernel/kernel.json', 'octave_kernel') ],
     ...
     )
  1. 通过在导入 oct2py 之前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')
