conda stuck on Proceed ([y]/n)? when updating packages in ipython console
提问by Aby
I just downloaded Anaconda 4.2.0 (with python 3.5.2) for Mac OS X. Whenever I try to update any packages etc, my ipython console presents the package dependencies and displays "Proceed ([y]/n)?" but does not take any inputs. E.g. I press enter, or y-enter etc. and nothing happens. Here's an example:
我刚刚为 Mac OS X 下载了 Anaconda 4.2.0（带有 python 3.5.2）。每当我尝试更新任何包等时，我的 ipython 控制台都会显示包依赖项并显示“Proceed ([y]/n)?” 但不接受任何输入。例如，我按 Enter 或 y-enter 等，但没有任何反应。下面是一个例子：
!conda create -n graphlab-env python=2.7 anaconda

Proceed ([y]/n)?
It won't respond after this step. When I enter 'Ctrl-C' it breaks out of this loop. I have tried Shift-Enter, Alt-Enter, Ctrl-Enter, Cmd-Enter etc but no luck. Tearing my hair out over this. Am I missing something?
这一步之后就没有反应了。当我输入 'Ctrl-C' 时，它会跳出这个循环。我尝试过 Shift-Enter、Alt-Enter、Ctrl-Enter、Cmd-Enter 等，但没有运气。把我的头发扯掉了。我错过了什么吗？

You can launch shell commands with the !operator in ipython, but you can't interact with them after the process has launched.
您可以!在 ipython 中使用操作符启动 shell 命令，但在进程启动后您无法与它们交互。
Therefore, you could:
因此，您可以：
- execute your conda command outside of your ipython session (IOW, a normal shell); or
- pass the
--yesflag. e.g.:
- 在你的 ipython 会话之外执行你的 conda 命令（IOW，一个普通的 shell）；或者
- 传递
--yes旗帜。例如：
In[2]: !conda create -n graphlab-env python=2.7 anaconda --yes
In[2]: !conda create -n graphlab-env python=2.7 anaconda --yes

If you add a '--yes' at the end of the command it works. For example:
如果您在命令末尾添加“--yes”，它会起作用。例如：
>>>!conda install seaborn --yes
回答by Karan Sharma
Just Append -y to any command to skip all the yes/no questions. Most of the packages are configured in a way to work with this. For your !conda create -n graphlab-env python=2.7 anaconda -y
只需将 -y 附加到任何命令即可跳过所有是/否问题。大多数软件包都以某种方式进行配置以处理此问题。对于你的 !conda create -n graphlab-env python=2.7 anaconda -y

Solution: !conda update --all --yes
解决方案：!conda update --all --yes
