This article introduces the relevant knowledge of "how to package dependent files to the target program directory for PyInstaller". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Problem of packaging dependent files to target program directory

I developed an application using PySide2, and to make it easier for others to use, I packaged it into * .exe using PyInstaller. The packaging mode is one-folder, that is, the generated object file is a folder containing the *. Exe file and all the files on which the *. Exe depends.

Open the folder and take a screenshot as follows:

Everything went well, but there was a problem that the program relied on several files (* .png, * .txt) to run, and without packaging me to the target directory, * .exe couldn't find the files and couldn't run.

Solution.

* use the configuration file .spec to specify that dependent files are packaged together.

Key parts of the configuration file:

A = Analysis (['MainWindow.py'], pathex= [' E:\\ 7-Pycharm\\ contrl_sys_ui'], binaries= [], datas= [(". / other", "other"), (". / QtDesigner", "QtDesigner")]

Datas this option to (original file path, target file path) tuple. The original file path is the path of the file / folder on the computer. When packing, PyInstaller will copy the original file we specified to the target file path according to the original file path we specified.

The target file path is based on the directory where the package generated target program is located.

For example, if my package directory is. / dist/MainWindow, then PyInstaller will copy. / other and. / QtDesigner to. / dist/MainWindow directory.

In the packaged target file, you can find that all the folders we want to package together have been packaged. The screenshot is as follows:

Pyinstaller package exe has dependent files

Do not set the pyinstaller configuration file on .spec, otherwise the update configuration file will not take effect. Use os.getcd () to get the exe execution path.
