带有 Python 的 PyInstaller：3.10.0b4 - ImportError：没有名为 _bootlocale 的模块

Question

I have Beta 4 of Python 10 installed (which I must use because I need pattern matching feature only available in v3.10):

C:\Users\myname\Documents\Projects\Project Migration\SeleniumExamplePy>py -3 --version
Python 3.10.0b4

and I made sure my pyinstaller is up to date:

    C:\Users\myname\Documents\Projects\Project Migration\SeleniumExamplePy>pip install --upgrade pyinstaller
Requirement already satisfied: pyinstaller in c:\users\myname\appdata\local\programs\python\python310\lib\site-packages (4.4)

Requirement already satisfied: future in c:\users\myname\appdata\local\programs\python\python310\lib\site-packages (from pefile>=2017.8.1->pyinstaller) (0.18.2)

I am getting ImportError: No module named _bootlocale error while trying to convert my python code that I thoroughly tested to executable:

ImportError: No module named _bootlocale

I looked at this comment https://bugzilla.redhat.com/show_bug.cgi?id=1899950 that AzyCrw4282 posted the link to in response to a very similar question PyInstaller - ImportError: No module named _bootlocale and there is a statement by Victor Stinner 2021-01-19 10:25:32 UTC

"Oh, _bootlocale was a private module which should not be imported directly. I removed it and replaced it with a new _locale._get_locale_encoding() function in Python 3.10"

So, if the module was removed, why the latest pyinstaller still tries to pull it in? Is it because I am using Python 3.10b4 and pyinstaller was not updated for it yet? Is there a way to exclude the _bootlocale module from the executable build to be able to build the executable?

I tested my program exhaustively and it works with no problem when run from.py. I do not call anything that directly refers to bootlocale module, not 100% sure what it does or did before being removed from 3.10.

Answer 1

It's a Python 3.10 compatibility issue, and it's mentioned here .

You can solve it by adding --exclude-module _bootlocale to your command.

For instance:

pyinstaller.exe app.py --exclude-module _bootlocale

Answer 2

Had the same problem, all you need is to install pyinstaller and then install the 3.10 support.

Use:

pip install pyinstaller
pip install https://github.com/rokm/pyinstaller/archive/refs/heads/python-3.10.zip

Answer 3

Try to install the latest version of Pyinstaller
This solves me the problem:

pip install pyinstaller==4.10

Answer 4

Add --exclude-module _bootlocale to the command line Solved for me. Thank you very much @LingYan Meng

Answer 5

Use this command to install pyinstaller first.

pip install pyinstaller==4.10

Or if you want to install the latest version of pyinstaller use:

pip install pyinstaller

After installing try to create your exe again and it will work.

Answer 6

This appears to be a version mismatch between pyinstaller and python. I recently upgraded to python3.10, installed from requirements.txt, and then had this issue. I was running pyinstaller 4.5.1, but the latest is pyinstaller 5.1. You can get the latest pyinstaller by doing the following:

pip install --upgrade pyinstaller

or

python -m pip install --upgrade pyinstaller

Answer 7

在我的情况下，我通过卸载 fbs 包解决了它

pip3 uninstall fbs

Answer 8

I fixed it in my poetry project by editing pyproject.toml:

[tool.poetry.dependencies]
python = "^3.8"

to

[tool.poetry.dependencies]
python = "^3.8,<3.11"
