Question

看起来像vnc的最佳选择是来自vncdotool模块。我一直在使用它与Python2没有任何问题。现在我转向Python3。它似乎在我的Mac上根本不起作用。这是问题所在。

创建venv并安装pip3后安装vncdotool。运行vncdo命令时出现立即错误。它说“打印数据”。看起来它正在运行Python2代码“print'xxx'vs print（'xxx'）”

当我在交互模式下运行python3，并尝试导入api模块时。我收到另一个错误，说Queue不可用。

我检查了github page，看到确实有python3支持。但是，互联网上没有太多信息。

模块，如你所知，不支持Python 3 - 堆栈跟踪中的代码显然只是py2-only。开发人员添加了＃3; Python 3＆＃34;到setup.py的元数据并不意味着支持已经完成 - 特别是考虑到最后一个版本（截至撰写本文时）早于in Mar 2016。

您可以安装模块的git HEAD版本，并查看支持是否有效。至少，您的程序窒息的command.py中的print语句已得到修复。

pip install git+https://github.com/sibson/vncdotool.git

建议的副本Python 2 and Python 3 dual development建议如何修复代码，使其在Python 2和3中运行。如果支持不完整，您可以将其余修复提供给维护者作为拉动请求。

python3上的vncdotool支持？
