AttributeError: 'str' object has no attribute '_MEIPASS'

Description of the issue

I've used pyinstaller to convert my py to exe. App is working fine, all of the features are working ok except "pyperclip.copy".
Even I have no issue with "pyperclip.paste", only copying to clipboard.

Context information (for bug reports)

Whenever I use the command "pyperclip.copy(copy_clipboard)" to copy string to clipboard, it doesn't work instead I get following error:

Exception in Tkinter callback
Traceback (most recent call last):
File "tkinter_init_.py", line 1884, in call

• Output of pyinstaller --version: 4.3

• Version of Python: 3.9.1

• Platform: Windows 10

• Did you also try this on another platform? No

• try the latest development version, using the following command: I've tried but it failed to create exe file.

I've tried all suggested workarounds but couldn't fix this issue. I'm not an advanced programmer so it might be silly issue although I appreciate any help in this regard. Thanks!

This looks like the sys module is being shadowed by a string variable...

Are you assigning a string to a variable called sys anywhere in your code?

This seems to be reproducer and it seems to affect only frozen application:

# sys='whatever'  # uncomment to reproduce the problem
import pyperclip
pyperclip.copy('The text to be copied to the clipboard.')
print(pyperclip.paste())

@rokm Thanks mate!
I changed sys variable to system_info afterwards it's working without any issue 🙏

This is still a bug? That sys = "string" is somehow finding its way into:

pyinstaller/PyInstaller/loader/pyiboot01_bootstrap.py

Line 128 in 7e27898

frozen_name = os.path.join(sys._MEIPASS, os.path.basename(name))

... where it certainly doesn't belong.

Yeah, this specific problem (overwriting sys or os with custom variable in global namespace) should be fixed if/when we move those ctypes classes and functions from pyboot01_bootstrap.py into a separate module (where the bound names of imported os and sys modules are module-scoped, and cannot be affected by global namespace variables).

The bootstrap script should be just a script, without any functions or classes that can be called or instantiated after the script itself has finished.
