OSError：[WinError -2147221005]无效的类字符串

完全追溯

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    for text in acad.iter_objects('Text'):

当我尝试从here编译此代码时，我收到此错误

from pyautocad import Autocad, APoint

acad = Autocad()
acad.prompt("Hello, Autocad from Python\n")
print(acad.doc.Name)

p1 = APoint(0, 0)
p2 = APoint(50, 25)
for i in range(5):
    text = acad.model.AddText('Hi %s!' % i, p1, 2.5)
    acad.model.AddLine(p1, p2)
    acad.model.AddCircle(p1, 10)
    p1.y += 10

dp = APoint(10, 0)
for text in acad.iter_objects('Text'):
    print('text: %s at: %s' % (text.TextString, text.InsertionPoint))
    text.InsertionPoint = APoint(text.InsertionPoint) + dp

for obj in acad.iter_objects(['Circle', 'Line']):
    print(obj.ObjectName)

几个小时后谷歌，我决定在这里想 可能是什么原因？

发生该特定错误是因为您的程序无法正确打开AutoCAD;但是当我自己打开AutoCAD然后运行代码时，会出现以下错误：

_ctypes.COMError：（ - 2147467262，'无兼容接口'，（无，无，无，0，无））

根据我的经验，COMError经常出现，因为与使用的程序连接不良。我将win32com与pyautocad结合起来解决了这个问题。对于这种特殊情况，它将是这样的：

from pyautocad import Autocad, APoint
import win32com.client

AutoCAD = win32com.client.Dispatch("AutoCAD.Application")
acad = Autocad(create_if_not_exists = False)

p1 = APoint(0, 0)
p2 = APoint(50, 25)

for i in range(5):
text = acad.model.AddText('Hi %s!' % i, p1, 2.5)
acad.model.AddLine(p1, p2)
acad.model.AddCircle(p1, 10)
p1.y += 10

dp = APoint(10, 0)
for text in acad.iter_objects(['Hi']):
    print('text: %s at: %s' % (text.TextString, text.InsertionPoint))
    text.InsertionPoint = APoint(text.InsertionPoint) + dp

for line in acad.iter_objects(dont_cast = True):
    print(line.ObjectName)

AutoCAD.Visible = True
