Question

我试图在我的一个python脚本中使用oct2py，我在C:\Octave\Octave-4.2.1中安装了八度音，并为我的用户帐户的PATH变量添加了C:\Octave\Octave-4.2.1。当我运行from oct2py import octave时，我收到以下错误：

Traceback (most recent call last):
  File "C:\Users\CVanCleef\Desktop\cvancleef reconstruction\filterTestin.py", line 12, in <module>
    from oct2py import octave

    octave = Oct2Py()

FileNotFoundError: [WinError 2] The system cannot find the file specified

编辑：在我的路径中添加OCTAVE_EXECUTABLE后，我收到错误

Answer 1

更改PATH变量后是否重新启动了系统？

我在加载到其他模块之前遇到过此问题，并通过重新启动系统解决了这个问题。

Answer 2

通过添加路径变量OCTAVE_EXECUTABLE并将OCTAVE_EXECUTABLE值设置为C:\Octave\Octave-4.2.1\bin\octave-cli.exe来修复。我还从PATH

中删除了八度音程

oct2py导入错误：系统找不到指定的文件
