如何使用pyenv安装ipython qtconsole（Python版本3.4.2）

问题描述

我使用的是Ubuntu 14.04。我安装了 pyenv ，然后在 pyenv 下安装了Python 3.4.2。然后我切换到版本3.4.2：

I am using Ubuntu 14.04. I installed pyenv and then installed Python 3.4.2 under pyenv. Then I switched to version 3.4.2:

$ pyenv global 3.4.2

现在我想安装 ipython 和 qtconsole ：

$ pip install ipython
$ ipython3 qtconsole &

这会给出错误消息（回溯未显示）：

This gives an error message (traceback not shown):

ImportError:
    Could not load requested Qt binding. Please ensure that
    PyQt4 >= 4.7 or PySide >= 1.0.3 is available,
    and only one is imported per session.

    Currently-imported Qt library:   Noneu
    PyQt4 installed:                 False
    PySide >= 1.0.3 installed:       False
    Tried to load:                   ['pyside', 'pyqt']

然后我试过：

$ pip install pyside

给出错误（某些部分）删除输出）：

which gives error (some parts of output removed):

Installing collected packages: pyside
  Running setup.py install for pyside
    Removing /tmp/pip_build_hakon/pyside/pyside_package
    Python architecture is 64bit
    Failed to locate a dynamic Python library, using /home/hakon/.pyenv/versions/3.4.2/lib/libpython3.4m.a
    qmake: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/qmake': No such file or directory
    Failed to query the Qt version with qmake /usr/bin/qmake

更新

从上一条错误消息中我想我必须这样做

From the previous error message I figured I had to do

$ sudo apt-get install qt4-qmake

然后我收到一些新的错误消息，这导致我运行：

And then I got some new error messages, which led me to run:

$ sudo apt-get install libxslt-dev
$ sudo apt-get install qt4-default

现在，当我跑步时：

$ pip install pyside

我收到错误（输出的第一部分被删除）：

I get error (first part of output cut out):

[ 83%] Building CXX object libshiboken/CMakeFiles/libshiboken.dir/shibokenbuffer.cpp.o

Linking CXX shared library libshiboken.cpython-34m.so

推荐答案

我想我找到了问题：

PySide构建显然需要一个python .. 3.4.so 共享库而不是静态（ .a）图书馆参见）：

Then reinstall Python with shared library support (see also https://github.com/yyuu/pyenv/issues/82):

$ env PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.4.2
$ pyenv global 3.4.2

然后安装 pyside

$ pip install pyside

然后安装 pygments 和 pyzmq ：

$ pip install pygments
$ pip install pyzmq

最后，你可以运行它：

$ pip install ipython
$ ipython qtconsole &
