How to activate different anaconda environment from powershell
提问by Hector Barbossa
I have two environments in anaconda, namely: root, 2env. When I open anaconda prompt, I can switch from rootto 2envby typing: activate 2env. I also have conda in my powershell, but when I open powershell and try to run conda activate 2envit gives the following error:
我在 anaconda 中有两个环境，即：root, 2env. 当我打开 anaconda 提示符时，我可以通过键入从root到切换2env：activate 2env。我的 powershell 中也有 conda，但是当我打开 powershell 并尝试运行conda activate 2env它时，会出现以下错误：
CommandNotFoundError: 'activate'
CommandNotFoundError: '激活'
Any suggestions on how to fix this?
对于如何解决这个问题，有任何的建议吗？

Although Conda previously did not support PowerShell, this is now resolved in Conda 4.6.
尽管 Conda 以前不支持 PowerShell，但现在在Conda 4.6 中解决了这个问题。
After adding Anaconda3/Scripts/to your PATH variable, you should be able to initialize Conda for use with powershell with:
添加Anaconda3/Scripts/到您的 PATH 变量后，您应该能够初始化 Conda 以与 powershell 一起使用：
conda init powershell
Afterwards, you can use condanormally:
之后就可以conda正常使用了：
conda activate base

I found this solution:
我找到了这个解决方案：
I've been building on BCSharp's excellent work at my own repo (currently on PR).
Just do:
conda install -n root -c pscondaenvs pscondaenvsYou need Conda 4.1 or above (check with conda info conda) - otherwise please install the latest version.
Behavior is exactly like CMD - use activate or deactivate appropriately. It's completely backwards compatible and will also launch both .ps1 and .bat activate.d/deactivate.d scripts.
我一直在我自己的 repo（目前在 PR 上）建立 BCSharp 的出色工作。
做就是了：
conda install -n root -c pscondaenvs pscondaenvs您需要 Conda 4.1 或更高版本（检查 conda info conda） - 否则请安装最新版本。
行为与 CMD 完全一样 - 适当地使用激活或停用。它完全向后兼容，还将启动 .ps1 和 .bat activate.d/deactivate.d 脚本。

I have been battling this issue for a while. I found a solution by using a batch script and calling call activate %env%. I hope this can help somebody.
我一直在与这个问题作斗争。我通过使用批处理脚本并调用call activate %env%. 我希望这可以帮助某人。

Here is a work around - start cmd shell . Run - activate . Check - conda env list . Start powershell - powershell .
这是一个变通方法 - 启动 cmd shell。运行-激活。检查 conda 环境列表。启动 powershell-powershell。
