Pyinstaller comes with errors when importing backtesting.py module

Question

I am using Windows 11 for Python code development. I have a large Python program that uses the backteting.py module. The program works fine when running it using Visual Studio Code or executing it in the console. However, when I create an EXE file using the Pyinstaller, the EXE file does not work. I managed to reduce the code to two instructions (see below) and yet the EXE program does not work.

import backtesting
print ("Hello")

I am getting the following warnings when I run the Pyinstaller.

115289 WARNING: Library user32 required via ctypes not found
115301 WARNING: Library msvcrt required via ctypes not found

In addition, I am also getting the following errors when I run the EXE file.

C:UsersmenbDocumentsteststest3test3>test3

Any help to solve this problem is highly appreciated.

I was able to successfully compile and run the two lines from your example using pyinstaller.

import backtesting
print ("Hello")

Steps to reproduce.

create a new virtual enviornment and install pyinstaller and backtesting
create main.py with your example code.
run
pyinstaller -F --collect-all backtesting main.py

or

pyinstaller -F --collect-all backtesting --collect-all bokeh --collect-all xyzservices main.py

then run: dist/main.exe

OUTPUT:

Hello
