Question

在使用Python 3.6构建新的conda环境后，PyQt5（pyqt == 5.6.0）从PyCharm（2019.1。版）初始化时遇到问题。

将ssh -Y放入框中后，可以从iPython shell构建绘图。

但是从PyCharm导入matplotlib会引发以下错误：

import matplotlib.pyplot as plt

跟随stacktrace并查看相关文件会使我相信这与conda安装或conda env中的软件包的PyCharm识别有关。

使用PyCharm的Matplotlib 2.2.2运行基于PyQt5的绘图时，是否还有其他人遇到过问题？

Answer 1

在安装pyqt时，我使用了conda。运行conda install时，PyQt软件包似乎已链接，而不是复制到环境中。链接显然不符合预期。

我通过指定--copy解决了这个问题。有关详情，请参见conda docs。这是完整的安装命令：

conda install pyqt==5.6.0 --copy

Answer 2

对我来说，问题是我通过pip安装了pyqt5，而pyqt已经通过conda安装了。运行：

conda remove pyqt
conda install matplotlib

PyCharm远程解释器（2019.1）+ Matplotlib导入错误
