异常：使用Pyinstaller时找不到PyQt5插件目录，尽管PyQt5甚至未被使用

Question

一个月前，我解决了Python 2.7的应用程序冻结问题，您可以看到here。此后，我将我的代码修改为Python3.5（使用Anaconda），它似乎正在工作。无法让pyinstaller使用Anaconda，因此切换到尝试使用标准Python 3.5编译器生成.exe。我使用的设置与上面链接（pyinstaller --additional-hooks-dir=. --clean --win-private-assemblies pipegui.py）中的设置相同，只是得到了以下错误消息：

`Exception: Cannot find PyQt5 plugin directories`

This可能是相关的？但我使用的是Pyinstaller，我没有setup.py，所以不知道如何利用那里的解决方案，如果有的话

我觉得这个错误消息很奇怪，因为我使用的不是PyQt5，而是PyQt4。以下是完整的输出：

我也不知道TypeError: a bytes-like object is required, not 'str'This可能与什么有关？我只在pickle中使用二进制模式几次，据我所知这是我的唯一用法：

pickle.dump( roiState, open( fileName, "wb" ) )
roiState = pickle.load(open(fileName, "rb"))

我在运行应用程序时没有任何错误，只有在尝试使用pyinstaller生成.exe时才会出现这些错误。为什么？

还要注意，上面的回溯中确实弹出了Anaconda3（为什么它要在那里寻找二进制文件？）但是我：

1. 从Anaconda卸载pyinstaller
2. Am使用标准的Python3.5（64位）编译器

我唯一能想到的可能是罪魁祸首是我不再使用Pyinstaller的开发版本（它只是flat在Python 3.5中不运行）。当我的代码为python 2.7编写时，我不得不使用开发人员版本来解决冻结问题here

Answer 1

我成功地修复了遇到的相同问题（conda 4.5.4，pyinstaller 3.4），而没有卸载conda：

pip install PyQt5

当我使用conda install jupyter seaborn时，conda已经安装了PyQt。有趣的是，使用conda install PyQt5并不能解决我的问题。我不知道为什么。不管怎样，我希望这能帮到外面的人。
