python - excel 访问被 win32 python pywin32 拒绝

Question

我的代码是

#Opens template for creating final report
excel = win32.dynamic.Dispatch('Excel.Application')
template = os.path.abspath((folderpath+'\Poop.xlsx'))
wb = excel.Workbooks.Open(template)
freshws= wb.Sheets("Fresh") #Sheet names must match perfectly
secws= wb.Sheets("sec")

cur.execute("Select * from FIRALL")
freshdata=list(cur.fetchall())
#writes to the first sheet
datarowlen=0
for i,a in enumerate(freshdata):
    datarowlen = len(a)
    for j,b in enumerate(a):
        freshws.Cells(i+1,j+1).Value = a[j]

cur.execute("Select * from SECVE")
secdata=list(cur.fetchall())
#writes to the second sheet
datarowlen=0
for i,a in enumerate(secdata):
    datarowlen = len(a)
    for j,b in enumerate(a):
        secws.Cells(i+1,j+1).Value = a[j]
#saves the report
wb.SaveAs()
wb.Close()

运行代码时出现的错误是

Traceback (most recent call last):
  File "main.py", line 369, in <module>
    wb = excel.Workbooks.Open(template)
  File "<COMObject <unknown>>", line 8, in Open
pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, 'Microsoft Excel'

我收到一个弹出对话框，提示访问被拒绝。该文件不是只读的，我是它试图打开的工作簿的所有者。我试过了

win32.gencache.EnsureDispatch('Excel.Application')

我仍然得到同样的错误。有什么我想念的吗？我转而使用动态思维，后期绑定(bind)可以解决这个错误。

我在尝试修复此代码时遇到的另一个错误是 Pywins -2147418111 错误。

我和一位同事正在诊断这个确切的问题。我不敢相信这是多么晦涩难懂，我们通过使用 .NET 等效代码搜索类似问题找到了解决方案:

要修复，请在 64 位架构的“C:\Windows\SysWOW64\config\systemprofile\”或 32 位服务器的“C:\Windows\System32\config\systemprofile\”中创建一个名为“Desktop”的文件夹。

这确实解决了一个完全相同的问题。
