How to install PyQt4 in anaconda?

pythonpyqtpyqt4anaconda

提问by user1223862

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?

从 PyQt4 网站,他们安装包的说明是下载 tarball 并使用配置文件。我有两个版本的 Python,一个是我的普通系统,另一个在 anaconda 中。我不确定如何在 anaconda 中安装它。是否有安装 PyQt4 的 conda 命令?

Successfully installed it on OSX using homebrew:

使用自制软件在 OSX 上成功安装它:

brew install sip
brew install pyqt     

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

它(当前)安装 PyQt4。Anaconda 是机器上的主要 python (OSX 10.8.5)。

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:

看起来最新版本的 anaconda 会强制在任何 pyqt 构建上安装 pyqt5.6,这对您的应用程序来说是致命的。在终端中,尝试:

conda install -c anaconda pyqt=4.11.4

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

它将提示降级 conda 客户端。在那之后,它应该是好的。

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

更新:如果您想知道可以安装哪些 pyqt 版本,请尝试:

conda search pyqt

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

更新:最新版本的 conda 安装了 anaconda-navigator。这取决于qt5,应该首先删除:

conda uninstall anaconda-navigator

Then install "newest" qt4:

然后安装“最新”qt4:

conda install qt=4

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:

@Alaaedeen's answer 的更新版本。您可以指定要安装的任何软件包的版本的任何部分。这可能会导致其他软件包版本发生变化。例如,如果您不关心您想要哪个特定版本的 PyQt4,请执行以下操作:

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

这将安装 PyQt 4 的最新次要版本和发行版。您可以指定所需版本的任何部分,而不仅仅是主要版本号。所以,例如

conda install pyqt=4.11

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

将安装最新(或最后)版本的 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.

请记住,安装不同版本的软件包可能会导致依赖它的其他软件包前滚或回滚到它们支持您想要的版本的位置。

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

好吧,这是另一种方式 - 您可以使用 python 来调用这些命令:

npm install -g pageres-cli

Then you can simply do this:

然后你可以简单地这样做:

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

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

或者,如果您安装了 wkhtmltoimage (sudo apt install wkhtmltopdf),只需执行以下操作:

wkhtmltoimage www....com filename.jpg

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

所以没有任何 lib 或其他任何问题,并从您的 python 项目中调用这些命令。
