Python pyautocad是否需要运行的autoCad软件？

我犯了一个错误。当我尝试将dwg AutoCAD文件转换为excel时。 我曾经 我犯了一个错误

这是我运行的脚本。autocad是否正在运行是使用此库pyautocad所必需的

      doc.Close(False)
      acad = None
wb.save("Exported.xls")

当我运行这个脚本时，我得到的错误是

  acad.doc.Open(cwd + "/" + f)

您将得到以下错误：

OSError:[WinError-2147221005]无效的类字符串

如果

您没有安装AutoCAD 如果您安装了一个版本，但试图实例化错误的版本，如：CreateObjectAutocad19.Application（当您安装AutoCAD20时）。 通常，库会省略版本号，因此Autocad.Application可以正常工作

---

如果安装了Autocad实例，则对Autocad的调用将启动该实例。

不，您不需要运行Autocad。但请确保正确安装。@Arnie97在安装AutoAdd:\autocad\U文件后仍会出现错误回溯上次调用：文件test.py，第37行，位于acad.doc.Opencwd+/+f文件C:\Users\nithish\AppData\Local\Programs\Python 37\lib\site packages\comtypes\client\lazybind.py，第182行，在调用者返回self.\u comobj.\u invokedescr.memid，descr.invkind，0，*args文件C:\Users\nithish\AppData\Local\Programs\Python\Python37\lib\site packages\comtypes\automation.py，第729行，在调用dp，var，None，argerr\u ctypes.comer:-2147352567，“发生异常”，“AutoCAD”，无，0，现在没有我收到这个错误cwd当时的值是多少？D:\autocad_files@reckfaceFile C:\Users\nithish\AppData\Local\Programs\Python\Python37\lib\site packages\comtypes\automation.py，第729行，在(调用dp，var，None，argerr)ctypes.comeror:-2147352567，“发生异常”。“方法在MDI模式下不可用。”。使用文档集合的打开方法。“，”AutoCAD“，”C:\\Program Files\\Autodesk\\AutoCAD 2019\\HELP\\OLE_ERR.CHM“，-2145320848，None@NithishAlbin最后尝试一件事：acad.app.Documents.open
