WinError 32 在运行脚本时不断出现，即使创建了临时目录也是如此。 我究竟做错了什么？

Question

我目前正在尝试编写一个 python 脚本来创建 ArcGIS Online 图层的备份，但我一直在使用此代码和基本上我运行的任何脚本获取 WinError 32。 我之前遇到过这个问题，所以我认为创建一个临时目录会有所帮助，但问题仍然存在，我对了解目录的工作方式并不完全有信心，所以我可能只是输入了不相关的代码。 我目前使用的代码如下（另请注意，我对编码非常陌生）：

# create a temporary directory since I keep getting a file in use error but this also doesnt fix it lol
import tempfile
 
with tempfile.TemporaryDirectory() as tmpdir:
     print('created temporary directory', tmpdir)
 
# Import necessary modules
import arcgis
from arcgis.gis import GIS
 
# Create a GIS object
gis = GIS("insert_link", "username", "password")
 
# Get the item that represents the layer that you want to copy
layer_item = gis.content.get("layer_ID")
 
# Create a copy of the layer
copy_item = layer_item.copy()
 
# Find any old copies of the layer and delete them
for item in gis.content.search(query="title:'Copy of {}'".format(layer_item.title)):
    if item.type == "Feature Layer":
        item.delete()
 
# Save the new copy of the layer
copy_item.save()
# one day I will see this
print("File Downloaded")

这是我得到的错误：

我也尝试过 python 3.11，但它给了我另一个错误，它无法打开孤立路径，我在网上找不到任何相关信息。 我也在另一台计算机上尝试过这个，以防我的 python 配置错误并且发生同样的问题。 我读过它可能是 python-certifi-win32 包，但是当我尝试卸载它时出现同样的错误。 在制作临时目录后缩进代码也不能解决 winerror 32 问题。

您正在使用tempfile.TemporaryDirectory作为上下文管理器（使用with ）：

with tempfile.TemporaryDirectory() as tmpdir:
    print('created temporary directory', tmpdir)

以这种方式使用时，目录会在缩进块的末尾自动删除：

在临时目录对象的上下文或销毁完成后，新创建的临时目录及其所有内容将从文件系统中删除。

无论您想在临时目录中做什么，都需要在缩进块内进行。
