Question

编辑：
在评论后完全重写问题。

如果我从解释器运行以下代码，则该代码运行正常，但如果运行与pyinstaller生成的.exe文件相同的程序，则该代码将失败并显示 [Errno 13] Permission denied: 'c:/test/test.docx'。另外，如果我从 admin cmd窗口运行相同的exe，则会收到相同错误。

这让我发疯了好几个小时。关于如何调试的任何想法？（这是在装有python 3.6的Windows 10企业PC上。）

"""
        test.py
"""
import os
import zipfile
file = r'c:/test/test.docx'
print(f"{file} os.path.exists? {os.path.exists(file)}")
print(f"{file} os.path.isfile? {os.path.isfile(file)}")
print(f"open {file}")
with open(file, "rb") as f:
    print(f"fread & print first 20 chars:")
    print(f.read()[0:20])

如果我使用python运行此代码：

C:\Users\<user>\AppData\Local\Programs\Python\Python36-32\Scripts>..\python test.py
c:/test/test.docx os.path.exists? True
c:/test/test.docx os.path.isfile? True
open c:/test/test.docx
fread & print first 20 chars:
b'PK\x03\x04\x14\x00\x06\x00\x08\x00\x00\x00!\x00\xecq\x1c\xa0\xf0\x01'

现在我生成一个exe文件：

如果我现在运行.exe：

C:\Users\<user>\AppData\Local\Programs\Python\Python36-32\Scripts>dist\test.exe
c:/test/test.docx os.path.exists? True
c:/test/test.docx os.path.isfile? True
open c:/test/test.docx
Traceback (most recent call last):
  File "test.py", line 7, in <module>
    with open(file, "rb") as f:

[3640] Failed to execute script test

编辑2：经过更多调查，这种情况发生在使用域级帐户通过“ Azure信息保护”对文件进行加密时。例如，此DLP程序是一种DRM，用于保护公司PC上的Office文件。奇怪的是，运行上面的代码会根据启动方式给出不同的结果。我本以为使用python启动.py并运行coresponding .exe将使用与用户相同的凭据，从而产生相同的结果，但结果不同。

已加密的文件已将FILE_ATTRIBUTE_ENCRYPTED位置1，可以通过以下方式检测到：

def is_encrypted(path):
    return os.stat(path).st_file_attributes & stat.FILE_ATTRIBUTE_ENCRYPTED

在我的情况下，用于加密的身份是链接到域的某种东西（因为我找不到关于它的文档，所以还不知道）。

从pyinstaller运行.exe时出现权限错误，但.py正常运行
