How to fix: Conda activation is not working?

Question

installed Python 3.7.3 and Anaconda and tried to activate it in the Anaconda Prompt.

activate %PATH%

but i get the error

activate does not accept more than one argument

What can I do about it ?

Why you're passing your PATH variable to the activate command? you shall pass the conda.sh path to that. — Farhood ET, Jun 09 '19 at 07:52
So I tried : activate C:\Users\Ich\Anaconda3\etc\profile.d\conda.sh .But then i get the error "Not a conda environment" — Da Nickste, Jun 09 '19 at 07:56

I think you didn't quite understand how conda works.

In conda, you need to first create your own environment. In this case, let's call it my_env.

conda create -n my_env python

Then, you can activate that environment with

conda activate my_env

Also, pay attention that the conda precedes the activate, using activate directly is obsolete.

Wow it does downloading packages right now. Hope this will help. Thanks Mate ! – Da Nickste Jun 09 '19 at 08:06
Did it work? If so, I would appreciate if you would mark this answer as correct. – Finomnis Jun 09 '19 at 08:35
yes. How can I mark this as correct ? (sorry I am completely new) – Da Nickste Jun 09 '19 at 08:59
There should be a check mark button below the upvote/downvote buttons for you. Should turn green if you click on it. – Finomnis Jun 09 '19 at 09:15

If you have space in path, please try this

activate "C:\Users\USER\New Project\"

Generally you have to specify the conda env full path.

same error "activate does not accept more than one argument ..." – Da Nickste Jun 09 '19 at 08:03
I generally activate conda using full path . have a look https://stackoverflow.com/questions/46929791/activating-conda-environment-with-its-full-path – Uzzal Podder Jun 09 '19 at 08:03
I have added a photo in edited answers. it works for me – Uzzal Podder Jun 09 '19 at 08:09

You only have to specify the full path if you don't use the default path. Otherwise you can just have the environment name as argument. – Finomnis Jun 09 '19 at 08:10
For demonstration I have showed you this image. But, in my work I have three servers, and a common shared filesystem. In that file system I keep my conda environment. when I try to access from other two server, I have no options to add `short environment name`, but `full path`. The other two server has only conda installed, but no information about the conda environment in the shared folder. I activate using full path. – Uzzal Podder Jun 09 '19 at 08:13

I don't think conda is meant to share environments between machines ... It only works if the different machines have the *exact* same setup. Isn't the beauty of conda that you can reproduce the same environment without needing a shared folder? – Finomnis Jun 09 '19 at 08:37

yes writing your argument in a closed quote worked for me if there is a space in between characters. So here's what I did with my issue:

>>> conda activate "C:\Users\Name\Desktop\sample_project_1\env"

If you use Linux you can start conda with command (assuming that conda was installed @ ~/miniconda3/)

source ~/miniconda3/bin/activate
or
source [conda_install_path]/bin/activate 
or
source [conda_install_path]/bin/activate base

By default, (base) virtual environment is loaded. You can switch to a different environment by

conda activate [env_name]

A sorter path is to type directly

source [conda_install_path]/bin/activate [env_name]

As usual, you can avoid re-typing activation commands every time by augmenting the .bash_rc script
