OSError：[Errno 8] Exec格式错误，Firefox引发异常。硒和壁虎

Question

我具有以下脚本，可将.asm文件转换为.8080程序集的.com文件。我已经为python 3安装了硒（因为脚本需要python3），并尝试安装geckodriver。

我按如下方式安装了硒：

$ sudo pip3 install selenium

我如下安装了geckodriver（至少尝试过）：

$ wget https://github.com/mozilla/geckodriver/releases/download/v0.18.0/geckodriver-v0.18.0-linux64.tar.gz
$ tar -xvzf geckodriver*
$ chmod +x geckodriver
$ sudo mv geckodriver /usr/local/bin

（https://askubuntu.com/questions/870530/how-to-install-geckodriver-in-ubuntu）

但是它会引发以下异常： OSError：[Errno 8]执行格式错误

这是脚本：

#!/usr/bin/env python3

"""
    selenium and geckodriver must be installed to use this script!

        if bin_file != -1:
