How to solve the problem of python UPX is not available

1. Error report

2. Error reason

Since pyinstaller uses UPX for packaging, the application was not found during packaging, resulting in Error!

3. Solution 1

Visit the UPX official website to download: https://upx.github.io, [I am using the Window 64 version], so the download is win64 compressed package!

Unzip the compressed package and obtain upx.exe

Copy upx.exe to the pyinstaller installation directory. [My pyinstaller installation directory: D:\Python\Scripts]

##Finally execute the packaging command again

pyinstaller -F app.py

4. Solution 2 [Uninstall pyinstaller]

pip uninstall pyinstaller

2. [Reinstall pyinstaller]

pip install pyinstaller

5. Solution three

Pay attention to the error: script ‘H:\A small tool developed by python 3.7\python 3.7 Convert base64 to images in batches\app.py’ not found

Because the name of my program is base64_to_png.py, I entered the wrong name [app.py] when packaging, resulting in [UPX is not available.】Error! ! ! Directly replace app.py with base64_to_png.py!

Note: Enter the name of the .py program you wrote yourself for the package, enter the name of the .py program you wrote yourself for the package, enter the name of the .py program you wrote yourself for the package! ! !
