PyInstaller "ValueError: source code string cannot contain null bytes" (ValueError: source code string cannot contain null bytes)

Question

我得到了一个 ValueError: source code string cannot contain null bytes 执行命令时 pyinstaller main.py 的cmd中，无论是否有管理员权限。

Traceback (most recent call last):

ValueError: source code string cannot contain null bytes

我试过用Notepad++删除代码中的NULL字符，也试过重新安装pyinstaller，但问题依然存在。

我能找到的唯一的解决办法是删除NULL字符，但是当我在Notepad++中用""(regex checked)替换"\x00 "时，没有任何内容被替换。

我想明白了。看来 pyinstaller 不兼容最新版本的 Python 3 (截至2020年5月24日)。我卸载了Python 3.8.3，安装了Python 3.7.7，安装了所有我在 main.py 并且成功了! 如此简单的解决方案。
