从命令行启动IPython qtconsole（安装所有依赖项后）

我对命令行有点生疏。我曾经在我的上一本MacBook上安装了IPython（配置了所有依赖项），这样我就可以单击仪表板上的图标来启动IPython qtconsole（在终端外壳之外）

现在，在我的新MacBook Pro上，在安装了所有相同的文件和依赖项之后，我得到了：

Jacobs-MacBook-Pro:~ Jacob$ ipython qtconsole

提前感谢您提供的任何提示。如果您需要我运行任何命令（查看更多输出），请告诉我

因此，您有多个Python安装，并且不确定您安装了哪一个

您有自制和MacPorts

你的MacPorts坏了，你不知道如何修复它

修复每一个问题可能并不难，但我认为是时候洗清历史，重新开始了

---

“简单”的方法是重新安装操作系统，使用标准的备份和迁移工具来保存Aqua级别的应用程序、用户首选项、文档等。但这是非常激烈的，不必要的

要手动清理，首先：

• brew卸载$（brew列表）

  。这将删除所有自制软件包。您可以只

  取消链接

  ，而不是

  卸载

  ，但您确实希望在清理计算机后重建它们

• sudorm-rf/Library/Python/Library/Frameworks/Python.framework/usr/local/share/Python*

  。这将消除大多数第三方Python安装。如果你不知道自己是从哪里来的，那真的是你能做的最好的了

看看

/usr/local/bin

中剩下的内容。各种各样的东西都可以在这里结束，从用苹果的Python安装的脚本到用于诸如TextMate、Aquamacs或GitHub等GUI应用程序的命令行工具，再到SDL或Qt二进制安装的工具，所以你可能不想一扫而光，但你确实想看一看。另请看

/usr/local/lib

和

/Library/Frameworks

您可能还需要编辑

~/.profile

等文件，以撤消您或那些安装程序所做的更改，例如将

/opt/local/bin

或

/Library/Frameworks/Python.framework/Versions/2.7/bin

添加到

路径中。
/etc
中也可能有更改，但这不太可能（也不太可能导致问题）

现在运行
brew doctor
以确保Homebrew运行正常，重新安装任何与Python无关的Homebrew软件包和二进制安装程序，现在您可以正确地安装/配置Python、PyQt4或PySide、iPython等，并在此后过上愉快的生活（直到您明年购买一台新计算机）.
我从未有过在mac或ubuntu上使用Qt绑定构建python的运气。一个选择是尝试使用一个对Qt有预编译支持的python发行版，比如Enthound Canopy（）或Anaconda（）。您使用的是苹果预安装的python 2.7、python.org的安装程序、自制软件包还是其他什么？您是否在自制软件的旁边安装了MacPorts或Fink？您是如何安装Qt、PyQt（或PySide？）和ipython的？如果你有任何东西的多个版本（请记住，如果你安装了任何Python，你会安装，因为苹果已经给了你一个），你的
路径是什么样子的？@RobertMcGibbon：只有OS X 10.8附带的Python 2.7.2（没有第三方安装），
brew install pyside
对我来说是开箱即用的。我还使用了自制的Python。但是python.org或除这两个以外的任何其他python都不能使用。（我也使用了MacPorts python/qt/pyqt4，多年来从10.4升级到10.7，没有问题。事实上，只有当你开始安装多个python，它们都想要声明一段/usr/local时，事情才会变得混乱……）注意到，@abarnert。我的经验是从源代码处编译一个新版本，并试图让它与gui后端相链接。在terminal中：“当我启动iPython（terminal，使用：iPython--pylab=inline）时，哪个python”/usr/bin/python）：“python 2.7.2…”打印在标题“我将在重建时睡觉——尽管如此，你确实简单明了地把它安排好了。”。我很感激，因为当我终于鼓起勇气去做的时候，麻烦就少了。非常感谢。
