如何在anaconda中安装PyQt4？

Question

From the PyQt4 website their instructions for installing the package are to download the tarball and use the config file. I have two versions of Python, one is my normal system and the other is within anaconda. I'm not sure how I get this to install within anaconda. Is there a conda command to install PyQt4?

Answer 1

Updated version of @Alaaedeen's answer . You can specify any part of the version of any package you want to install. This may cause other package versions to change. For example, if you don't care about which specific version of PyQt4 you want, do:

conda install pyqt=4

This would install the latest minor version and release of PyQt 4. You can specify any portion of the version that you want, not just the major number. So, for example

conda install pyqt=4.11

would install the latest (or last) release of version 4.11.

Keep in mind that installing a different version of a package may cause the other packages that depend on it to be rolled forward or back to where they support the version you want.

FYI

PyQt is now available on all platforms via conda!
Use conda install pyqt to get these #Python bindings for the Qt framework. @ 1:02 PM - 1 May 2014

Answer 3

It looks like the latest version of anaconda forces install of pyqt5.6 over any pyqt build, which will be fatal for your applications. In a terminal, Try:

conda install -c anaconda pyqt=4.11.4

It will prompt to downgrade conda client. After that, it should be good.

UPDATE: If you want to know what pyqt versions are available for install, try:

conda search pyqt

UPDATE: The most recent version of conda installs anaconda-navigator. This depends on qt5, and should first be removed:

conda uninstall anaconda-navigator

Then install "newest" qt4:

conda install qt=4

Answer 4

Successfully installed it on OSX using homebrew:

brew install sip
brew install pyqt     

which (currently) installs PyQt4. Anaconda is the main python on the machine (OSX 10.8.5).

How to install PyQt4 on anaconda python 2 on Windows:

At first I have tried to isntall pyqt4 via pip install :

C:\\Users\\myuser\\Anaconda2\\Scripts\\pip.exe search pyqt4 > pyqt4.txt

It shows:

PyQt4 (4.11.4) - Python bindings for the Qt cross platform GUI toolkit

But when I tried to install, it gives an error:

C:\Users\myuser\Anaconda2\Scripts\pip.exe install PyQt4
Collecting PyQt4
  Could not find a version that satisfies the requirement PyQt4 (from versions:
)
No matching distribution found for PyQt4

Seems this answer is realated to this problem: https://superuser.com/a/725869/213959

Then I have tried to install it via conda install ( How to install PyQt4 in anaconda? ) :

C:\Users\myuser\Anaconda2\Scripts\conda.exe search pyqt

It shows:

                             5.6.0            py36hb5ed885_5  defaults  

But it gives error:

C:\Users\myuser\Anaconda2\Scripts\conda.exe install pyqt=4.11.4
Fetching package metadata .............
Solving package specifications: .

UnsatisfiableError: The following specifications were found to be in conflict:

  - pyqt 4.11.4* -> sip >=4.16.4,<4.18

Same with -c parameter:

Then I tried to uninstall pyqt :

C:\Users\myuser\Anaconda2\Scripts\conda.exe uninstall pyqt

And installed it again:

C:\Users\myuser\Anaconda2\Scripts\conda.exe install -c anaconda pyqt=4.11.4

And finnaly it works!

Answer 6

Well, here is another way - you could use python to call these commands:

npm install -g pageres-cli

Then you can simply do this:

pageres google.com --format=jpg --filename=...

Or if you have wkhtmltoimage installed (sudo apt install wkhtmltopdf), simply do this:

wkhtmltoimage www....com filename.jpg

So no trouble with any lib or whatever anymore and call these commands from within your python project.
