我使用VIRTUALENV与我的发展环境与利润web.py,simplejson以及其他面向Web的包.
我将使用Qt开发一个简单的python客户端来重用一些用web.py开发的Api.
这里有人用Virtualenv成功安装了PyQt4吗？
可能吗？
我已经下载了所有二进制文件并已PyQt4在我的python2.6目录中全局安装.
如果我不使用--no-site--packages选项,Virtualenv正确地包含PyQt4在我的新沙箱中,但显然,包含我不需要的所有全局包.
有没有一种干净的方法来准备一个新的沙盒--no-site--packages选项,然后添加PyQt4或PySide使用pip,easy_install或其他一些魔术？
它应该足以创建一个空的virtualenv,然后将.../site-packages/PyQt4目录的内容复制到其中.
我建议全局安装一次PyQt4,制作目录的副本,卸载它然后使用这个技巧来创建VE.
我也有同样的问题.我使用virtualenvwrapper,所以我编写了这个脚本来在每个新的虚拟环境中创建一个指向PyQt的链接.也许对其他人有用:
#!/bin/bash
# This hook is run after a new virtualenv is activated.
# ~/.virtualenvs/postmkvirtualenv
LIBS=( PyQt4 sip.so )
PYTHON_VERSION=python$(python -c "import sys; print (str(sys.version_info[0])+'.'+str(sys.version_info[1]))")
VAR=( $(which -a $PYTHON_VERSION) )
GET_PYTHON_LIB_CMD="from distutils.sysconfig import get_python_lib; print (get_python_lib())"
LIB_VIRTUALENV_PATH=$(python -c "$GET_PYTHON_LIB_CMD")
LIB_SYSTEM_PATH=$(${VAR[-1]} -c "$GET_PYTHON_LIB_CMD")
for LIB in ${LIBS[@]}
do
ln -s $LIB_SYSTEM_PATH/$LIB $LIB_VIRTUALENV_PATH/$LIB
done
链接到要点
Linux debian,python 2.7:
安装python-qt4 globaly: sudo apt-get install python-qt4
创建PyQt4与虚拟环境的符号链接 ln -s /usr/lib/python2.7/dist-packages/PyQt4/ ~/.virtualenvs/myEnv/lib/python2.7/site-packages/
创建sip.so的符号链接到您的虚拟环境ln -s /usr/lib/python2.7/dist-packages/sip.so ~/.virtualenvs/myEnv/lib/python2.7/site-packages/
对于那些想在Python 3 virtualenv(在OSX上)使用PyQt4的人,首先安装PyQt4和SIP(我将使用自制软件)
$ brew install python3 $ brew install sip --with-python3 $ brew install pyqt --with-python3
然后创建您的虚拟环境
$ virtualenv ...
最后是符号链接(为您机器上安装的版本更改SIP,PyQt4和Python的版本)
$ ln -s /usr/local/Cellar/sip/4.15.5/lib/python3.4/site-packages/*.* ~/{VIRTUALENVHOME}/{VIRTUALENVNAME}/lib/python3.4/site-packages/
$ ln -s /usr/local/Cellar/pyqt/4.10.4/lib/python3.4/site-packages/PyQt4/*.* ~/{VIRTUALENVHOME}/{VIRTUALENVNAME}/lib/python3.4/site-packages/PyQt4
我问是否可以在irc.freenode.net #pyside频道的virtualenv中安装PySide并得到hugopl的肯定回答.所以我按照PySide Binaries for Microsoft Windows的说明进行操作.输出如下.

让我们假设您的virtualenv名为myProject,并且您正在使用virtualenvwrapper.还假设了一个Unix平台.
$ workon myProject $ pip install --no-install SIP $ pip install --no-install PyQt $ cd ~/.virtualenvs/myProject/build/SIP $ python configure.py $ make $ make install $ cd ~/.virtualenvs/myProject/build/PyQt $ python configure.py $ make $ make install $ cd && rm -rf ~/.virtualenvs/myProject/build # Optional.
最简单的方法是安装:vext.pyqt4
这将为PyQt4您的virtualenv 添加单个系统包.
Ubuntu 16.04用法:
sudo apt install python3-pyqt4 mkvirtualenv --python=python3.5 venv pip install --no-use-wheel vext.pyqt4
