Dear all,

I hope you are well.  
I am struggling with the installation of the biobakery\_workflows package

Installed anaconda, created an environment with python v3.7.7

Running  
_conda install -c biobakery biobakery\_workflows_

leads to:  
_UnsatisfiableError: The following specifications were found_  
_to be incompatible with the existing python installation in your environment:_

_Specifications:_

- 
  - biobakery\_workflows → python[version=’\>=3.8,\<3.9.0a0’]\*

_Your python: python=3.7.7_

which leads me to update python to a newer version (v3.8.5);

rerunning the biobakery\_workflows package installation it leads to:

_UnsatisfiableError: The following specifications were found_  
_to be incompatible with the existing python installation in your environment:_

_Specifications:_

- 
  - biobakery\_workflows → python[version=’\>=2.7,\<2.8.0a0|\>=3.7,\<3.8.0a0’]\*

_Your python: python=3.8_

I am a bit confused. What am I missing?

Thanks for your help!

BW,  
Annika

I have stumbled upon the same problem.  
I tried to work in different conda environments with different versions of python.  
When the version was 3.9.5 I got:

_UnsatisfiableError: The following specifications were found_  
_to be incompatible with the existing python installation in your environment:_

_Specifications:_

- 
  - biobakery\_workflows → python[version=’\>=2.7,\<2.8.0a0|\>=3.7,\<3.8.0a0’]\*

But with python 3.7 I got the same error messages but with the requirements:  
_- biobakery\_workflows → python[version=’\>=3.8,\<3.9.0a0|\>=3.9,\<3.10.0a0’]_

My guess is that there is another issue as I also get:  
_The following specifications were found to be incompatible with your system:_

- 
  - feature:/linux-64::\_\_glibc==2.17=0\*

- 
  - python=3.9 → libgcc-ng[version=’\>=7.5.0’] → \_\_glibc[version=’\>=2.17’]\*

I figured that it might be a problem regarding channels and their configurations. I tried to add the biobakery channel into the .condarc file but it didn’t work. Then I stumbled upon this post and it did:

Hello, Thank you both for the post. Thank you for also posting your solution. That totally makes sense that updating your channels and their configurations resolved the issue with installing the package and its dependencies.

Thank you,  
Lauren
