Question

我正在尝试在mu ubuntu 14.o4 LTS上安装PyQt4。安装手册说在安装PyQt之前，必须安装sip版本至少版本4.16。因此，我下载了存档并按照here

给出了它

python configure.py

然而，当我输入sip -V以了解sip的版本时，我得到4.15。此外，如果在这个阶段我尝试安装PyQt，安装中止说需要至少版本4.16的sip版本所以，我试图通过pip uninstall sip卸载以前安装的sip。这引发了一个错误，我在这里粘贴了pip.log的内容。

/usr/bin/pip run on Thu Oct  9 06:48:46 2014
Cannot uninstall requirement sip, not installed
Exception information:
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 122, in main
    status = self.run(options, args)
  File "/usr/lib/python2.7/dist-packages/pip/commands/uninstall.py", line 59, in run
    requirement_set.uninstall(auto_confirm=options.yes)
  File "/usr/lib/python2.7/dist-packages/pip/req.py", line 1035, in uninstall
    req.uninstall(auto_confirm=auto_confirm)
  File "/usr/lib/python2.7/dist-packages/pip/req.py", line 505, in uninstall
    raise UninstallationError("Cannot uninstall requirement %s, not installed" % (self.name,))
UninstallationError: Cannot uninstall requirement sip, not installed

它清楚地表明系统上没有安装sip。我对这里发生的事感到困惑。请帮忙。

修改另请注意，python中的import sip确认没有名为sip的模块。

为PyQt4安装sip4.16.3时出错
