当我尝试ipython qtconsole
从 Python 安装目录以外的任何地方启动时,我收到导入错误。它似乎只有在我 RUN->cmd.exe 时才有效;cd C:\Users\me\python\Python27; ipython qtconsole;。
我试过批处理文件,但如果我不在我的安装目录的上下文中运行它,它似乎仍然不起作用。总是 ipython-script 似乎在抱怨。这是输出...(这是来自 ipython 内部,使用 CurrentWorkingDirectory 作为我的桌面)
In [2]: !ipython qtconsole

ImportError: Cannot import PySide >= 1.0.3 or PyQt4 >= 4.7
就像我说的,它在我的安装目录中运行得非常好,而且我 96% 确定我的 ENV 变量 PATH、PYTHONPATH、PYTHONHOME 是洁净的。我已经从删除它们到一次完全重载一个目录,结果没有任何变化。
而且我已经确保存在 Wow6432None Python 条目(我尽量不污染这些条目)。
Ipython 不是唯一出现此类错误的模块(也有相同的解决方案),但这绝对是最烦人的(我无法从 Run Prompt 启动 qtconsole!)
编辑::我确实挖掘了一个开始菜单条目,在更改“开始”属性后,我能够启动 qtconsole,但我仍然不太明白为什么相对于当前目录执行此导入。
