Conda无法在Power Shell中激活 [英] Conda not activate in Power Shell

问题描述

我已经在Windows 10笔记本电脑上安装了anaconda.我正在尝试激活名为 pyenv 的Python环境.

首先，我在笔记本电脑中检查 conda env列表，这是电源外壳上的输出:

  PS C:\ Users \ User>conda环境列表#conda环境:#基本* C:\ Users \ User \ Anaconda3pyenv C:\ Users \ User \ Anaconda3 \ envs \ pyenv 

然后我激活 pyenv :

  PS C:\ Users \ User>康达激活pyenv 

但是我再次检查，它仍然会激活 base 环境:

  PS C:\ Users \ User>conda环境列表#conda环境:#基本* C:\ Users \ User \ Anaconda3pyenv C:\ Users \ User \ Anaconda3 \ envs \ pyenv 

当我使用Anaconda提示符时，它可以正常工作:

 (base)C:\ Users \ User> conda激活pyenv(pyenv)C:\ Users \ User> 

有人知道为什么会导致此问题以及如何解决此问题吗?

更新:

运行 conda初始化powershell :

  PS C:\ Users \ User>conda初始化powershell不变C:\ Users \ User \ Anaconda3 \ Scripts \ conda.exe不变C:\ Users \ User \ Anaconda3 \ Scripts \ conda-script.py不变C:\ Users \ User \ Anaconda3 \ Scripts \ conda-env-script.py不变C:\ Users \ User \ Anaconda3 \ condabin \ conda.bat不变C:\ Users \ User \ Anaconda3 \ Library \ bin \ conda.bat不变C:\ Users \ User \ Anaconda3 \ condabin \ _conda_activate.bat不变C:\ Users \ User \ Anaconda3 \ condabin \ rename_tmp.bat不变C:\ Users \ User \ Anaconda3 \ condabin \ conda_hook.bat不变C:\ Users \ User \ Anaconda3 \ Scripts \ activate.bat不变C:\ Users \ User \ Anaconda3 \ condabin \ activate.bat不变C:\ Users \ User \ Anaconda3 \ condabin \ deactivate.bat修改后的C:\ Users \ User \ Anaconda3 \ etc \ profile.d \ conda.sh修改后的C:\ Users \ User \ Anaconda3 \ etc \ fish \ conf.d \ conda.fish不变C:\ Users \ User \ Anaconda3 \ shell \ condabin \ Conda.psm1修改后的C:\ Users \ User \ Anaconda3 \ shell \ condabin \ conda-hook.ps1不变C:\ Users \ User \ Anaconda3 \ Lib \ site-packages \ xontrib \ conda.xsh修改后的C:\ Users \ User \ Anaconda3 \ etc \ profile.d \ conda.csh修改后的C:\ Users \ User \ Documents \ WindowsPowerShell \ profile.ps1 

更新2:在使用CMD时有效:

  C:\ Users \ User> conda激活pyenv(pyenv)C:\ Users \ User> 

解决方案

过一会儿，当我打开Powershell时，我的Powershell出现了此错误.

 .:无法加载文件C:\ Users \ User \ Documents \ WindowsPowerShell \ profile.ps1，因为正在运行的脚本是在此系统上禁用.有关更多信息，请参见about_Execution_Policies，网址为https://go.microsoft.com/fwlink/?LinkID=135170.在第1行:3个字符+.'C:\ Users \ BinoyGhosh \ Documents \ WindowsPowerShell \ profile.ps1'+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+ CategoryInfo:SecurityError:(:) []，PSSecurityException+ FullyQualifiedErrorId:UnauthorizedAccess 

然后我发现了这个

I have already install anaconda on my Windows 10 laptop. I'm trying to activate the Python environment named pyenv.

First, I check the conda env list in my laptop, this is the output on the power shell:

PS C:\Users\User> conda env list
# conda environments:
#
base                  *  C:\Users\User\Anaconda3
pyenv                    C:\Users\User\Anaconda3\envs\pyenv

Then I activate pyenv:

PS C:\Users\User> conda activate pyenv

But I check again, it still activates base environment:

PS C:\Users\User> conda env list
# conda environments:
#
base                  *  C:\Users\User\Anaconda3
pyenv                    C:\Users\User\Anaconda3\envs\pyenv

When I use the Anaconda prompt, it works normally:

(base) C:\Users\User>conda activate pyenv

(pyenv) C:\Users\User>

Does anyone know why it causes this problem and how to fix this?

Update:

Running conda init powershell:

PS C:\Users\User> conda init powershell
no change     C:\Users\User\Anaconda3\Scripts\conda.exe
no change     C:\Users\User\Anaconda3\Scripts\conda-script.py

modified      C:\Users\User\Documents\WindowsPowerShell\profile.ps1

Update 2: It works when using CMD:

C:\Users\User>conda activate pyenv

(pyenv) C:\Users\User>

解决方案

After a while, my Powershell appear this error when I open it.

. : File C:\Users\User\Documents\WindowsPowerShell\profile.ps1 cannot be loaded because running scripts is
    disabled on this system. For more information, see about_Execution_Policies at
    https:/go.microsoft.com/fwlink/?LinkID=135170.
    At line:1 char:3
    + . 'C:\Users\BinoyGhosh\Documents\WindowsPowerShell\profile.ps1'
    +   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        + CategoryInfo          : SecurityError: (:) [], PSSecurityException
        + FullyQualifiedErrorId : UnauthorizedAccess

Then I found this solution.

• Run Powershell as Administrator
• Run this line set-executionpolicy remotesigned
• Close the terminal

Then it works.
