Usage

Usage: python pyisrepack.py -ori <exe file> -p <pyc file> -o <output file>

How To Do

---

这是Demo代码, 使用 PyInstaller 将其打包为 main.exe

import sys
from PySide6.QtCore import Qt
from PySide6.QtWidgets import QApplication, QLabel


def main():
    app = QApplication(sys.argv)
    label = QLabel("Hello world.", alignment=Qt.AlignmentFlag.AlignCenter)
    label.resize(300, 200)
    label.show()
    sys.exit(app.exec())


if __name__ == "__main__":
    main()

运行效果如下

我们将通过以下步骤将 Hello world 改为 Hello earth

Step1. 使用 pyinstxtractor 将 exe 拆包

python pyinstxtractor.py main.exe

得到如下文件

其中main.pyc是我们要修改的文件

Step2. 使用 uncompyle6 将 pyc 文件反编译成 python 源文件

uncompyle6 -o . main.pyc

Step3. 修改python代码

label = QLabel("Hello earth.", alignment=Qt.AlignmentFlag.AlignCenter)

Step4. 将修改后的python源代码编译成 pyc

uncompyle6 -c main.py

Step5. 使用 pyisrepack.py 将 pyc 重新压入 exe

python pyisrepack.py -ori main.exe -p main.pyc -o new_main.exe

Step6. 运行效果

Important

• 修改前后应尽量保证 Python 版本一致
• 目前只支持exe中 类型为 "s" 的条目。

使用 pyi-archive_viewer 查看条目类型
