• how to activate in Git Bash

CNNEZHA2@CN-L-0401092 MINGW64 ~/AppData/Local/Continuum/Anaconda3/envs/Py36/Scripts/her_env/Scripts

- How to directly activate in PoSh

PS C:\Users\CNNEZHA2> .\\AppData\Local\Continuum\Anaconda3\envs\Py36\Scripts\her_env\Scripts\activate
(her_env) PS C:\Users\CNNEZHA2> activate
(her_env) PS C:\Users\CNNEZHA2> deactivate
PS C:\Users\CNNEZHA2> activate
(my_env) PS C:\Users\CNNEZHA2>
(my_env) PS C:\Users\CNNEZHA2> deactivate
PS C:\Users\CNNEZHA2> .\\AppData\Local\Continuum\Anaconda3\envs\Py36\Scripts\her_env\Scripts\activate
(her_env) PS C:\Users\CNNEZHA2>

![](Pi%204)

How such a big keng!!!! Make sure you login with the Powershell Administrator!!!!!!

1. Then I try "\Scripts\my_env\Scripts\activate" is still not working in PoSh

2. Then I directly cd to the fold: C:\Users\CNNEZHA2\AppData\Local\Continuum\Anaconda3\envs\Py36\Scripts\my_env\Scripts

3. And with directly : PS C:\Users\CNNEZHA2\AppData\Local\Continuum\Anaconda3\envs\Py36\Scripts\my_env\Scripts> activate.ps1

4. Final results:(my_env) PS C:\Users\CNNEZHA2\AppData\Local\Continuum\Anaconda3\envs\Py36\Scripts\my_env\Scripts>

After the restarting of the PoSh, you can test like this; :), pls note the (my_env)

     Windows PowerShell

PS C:\Users\CNNEZHA2> activate
(my_env) PS C:\Users\CNNEZHA2> deactivate
PS C:\Users\CNNEZHA2>

2.1 Environment Variables

Environment Variables is soooooo important, you need to add the fold which your module is in.

%SystemRoot%\system32\WindowsPowerShell\v1.0\;C:\Windows\System32;%SystemRoot%\system32\WindowsPowerShell\v1.0\;C:\Windows\System32;%SystemRoot%\system32\WindowsPowerShell\v1.0\;C:\Users\CNNEZHA2\AppData\Local\Continuum\Anaconda3\envs\Py36;C:\Users\CNNEZHA2\AppData\Local\Continuum\Anaconda3\envs\Py36\Scripts\my_env\Scripts;C:\Users\CNNEZHA2\AppData\Local\Continuum\Anaconda3\envs\Py36;C:\Users\CNNEZHA2\AppData\Local\Continuum\Anaconda3\envs\Py36\Scripts

2.2 Execution Policy

Make sure you login the Powershell in Administrator!!

use code in Powershell, and with Yes for the second step, then all your downloading scripts can be executed by win Powershell.
