我想在Anaconda Python中安装cvxopt。这是我的软件版本：
$ python --version
Python 3.6.5 :: Anaconda, Inc.
$ conda --version
conda 4.5.11
$ anaconda --version
anaconda Command line client (version 1.6.14)
我尝试通过键入以下内容进行安装：
conda install cvxopt
系统提示我将下载大约40个软件包，将安装大约10个新软件包，将删除软件包
anaconda，以及将更新大约25个软件包？是新包依赖吗？
为什么conda会删除
anaconda包？康达不是水蟒的一部分吗？这是完整的输出：

最佳答案
anaconda程序包称为“元程序包”，因为它本身不包含任何代码，而是指定了应安装的其他程序包的依赖项。软件包cvoptx不是anaconda软件包指定的软件包之一，因此，如果您尝试安装cvoptx，则conda会通过删除anaconda软件包解决冲突（因为您给了cvoptx通过指定要在环境中安装的优先级来获得更高的优先级）。conda和anaconda是单独的，并且具有单独的版本。 conda是命令行界面，可用于安装，更新和删除程序包和环境。上面描述了anaconda。
最后（令人困惑），命令行上的anaconda命令由anaconda-client包提供，而不是anaconda包提供。如果要查看已安装的Anaconda的版本，请使用conda list anaconda。如果要使用anaconda-client命令行工具的版本，请使用anaconda --version。 anaconda-client用于将软件包和环境上传到https://anaconda.org
