在当前通道中找不到时，如何在conda env（运行3.6）中安装特定的awscli版本

Question

我正在尝试在我的conda环境（运行python3.6）中安装awscli的特定版本。正如另一篇文章中所建议的，我已经尝试将conda-forge添加到我当前的频道中。在

当我运行命令conda install -p /Users/myname/anaconda3/envs/py36 awscli==1.11.156 -y

此消息出错：

引用杰克·范德普拉斯的话：

If all you are doing is installing Python packages within an isolated environment, conda and pip+virtualenv are mostly interchangeable, modulo some difference in dependency handling and package availability. By isolated environment I mean a conda-env or virtualenv, in which you can install packages without modifying your system Python installation.

您可以尝试激活虚拟环境，然后使用任何标准方法进行安装。假设您已经创建了一个名为py36的conda虚拟环境：

$ source activate py36

或者在窗户上

然后只需使用任何标准安装方法，例如：

$ pip install awscli==1.11.156

$ easy_install https://github.com/aws/aws-cli/archive/1.11.156.tar.gz

缺点是conda没有管理使用pip安装的包的依赖关系，但在大多数情况下它是可以的。在
