'Can't install Spyder through Anaconda Navigator

I cannot install Spyder through Anaconda Navigator. I am a complete beginner when it comes to Python and I have no idea what's going wrong.

I have to create a new environment and open a project there.

What I did so far is: through Anaconda Navigator (1.9.7) I created a new environment (with Python 3.6). Then, for this specific environment I try to install Spyder. I click the 'install' button, a progress bar appears and then nothing happens.

I tried the same steps on friend's laptop and when I click install there, the progress bar also appears. When it's done the 'install' button changes to 'launch'. The only difference that I see between our computers is that I have Windows10 and he has a Macbook. I don't know whether this could be the problem somehow.

How can I install Spyder for a specific environment? What's going wrong with my installation in Anaconda Navigator?

Also, when I try to install Spyder through Anaconda Prompt (with Administrator privileges), I get the following error:

Preparing transaction: done
Verifying transaction: done
Executing transaction: failed
ERROR conda.core.link:_execute(568): An error occurred while installing package 'defaults::openssl-1.1.1b-he774522_1'.

I managed to solve this by going to the directory where the file libssl-1_1-x64.dll is located (in your case, C:\Users\eweli\Anaconda3\envs\HAABSA\Library\bin\). Then, I removed the file (by cutting and pasting it to the desktop, just to be safe) and ran the installation command again in an Anaconda prompt (with admin rights):

conda install -c anaconda spyder

After that, the installation went smoothly and a new version of libssl-1_1-x64.dll was created in the corresponding directory (thus I deleted the one I moved previously).

To install spyder, go to the command line and to the directory where you work. Activate your virtual environment by typing

conda activate environment_name

Then once that returns just type

conda install spyder

This should install spyder in your virtual environment.

I had the same issue today, and weirdly a lot of versions didn't work out for me. However, what worked was to go to anaconda prompt, activate the environment and then type

conda install -c conda-forge spyder

Solution 4:^[4]

Go the directory of your environement in terminal and type :

conda install -c anaconda spyder

it worked well for me.
