On Windows 10 I have Miniconda3 installed under C:/home/miniconda3
I'm using Cygwin (bash shell emulator) and within the Cygwin shell (at the command line) I'm trying to create a virtual environment using Conda.
I am creating an environment using Conda and it appears to be created OK, however when I activate and then try to use the environment I get an error that appears to show that there's something amiss with the environment that's been created. Here's what I've tried so far:
Start with a fresh Miniconda installation (downloaded and installed today), and list the environments:
$ conda env list
# conda environments:
#
base * C:\home\miniconda3
Create an environment:
$ conda create -n test_env
Solving environment: ...working... done
## Package Plan ##
environment location: C:\home\miniconda3\envs\test_env
Proceed ([y]/n)?
Preparing transaction: ...working... done
Verifying transaction: ...working... done
Executing transaction: ...working... done
#
# To activate this environment, use:
# > activate test_env
#
# To deactivate an active environment, use:
# > deactivate
#
# * for power-users using bash, you must source
#
Display the environments again, showing that the environment was created:
$ conda env list
# conda environments:
#
base * C:\home\miniconda3
test_env C:\home\miniconda3\envs\test_env
Activate the new environment, using source (since Cygwin is running bash). Now when I list the environments I expect to see an asterisk next to the test environment's name, indicating that it's now the active environment, but that's missing:
$ source activate test_env
$ conda env list
# conda environments:
#
base C:\home\miniconda3
test_env C:\home\miniconda3\envs\test_env
At this point I can try using Conda commands and they'll all fail since the environment's not being found and/or the environment itself is incomplete/malformed/corrupted:
$ conda list
EnvironmentLocationNotFound: Not a conda environment: C:\home\miniconda3\envs\test_env
$ conda install pandas
EnvironmentLocationNotFound: Not a conda environment: C:\home\miniconda3\envs\test_env
$ conda update pandas
PackageNotInstalledError: Package is not installed in prefix.
prefix: C:\home\miniconda3\envs\test_env
package name: pandas
When I try to deactivate the environment I get the following errors:
$ source deactivate
': not a valid identifierULT_ENV
': not a valid identifier
': not a valid identifierIX
': not a valid identifierPT_MODIFIER
': not a valid identifierON_EXE
What might be going wrong, and how can I fix this?
Running conda under Cygwin is not fully supported, and the recommended solution for users who want to run conda and associated conda environments in a Linux like shell on Windows is to use the bash shell that comes included with the git client for Windows
