Conda-build: Windows error: "conda activate" fails because shell is not initialized

[nicoddemus]

Hi,

After updating to conda 4.6.1, I'm getting this error when I try to build a recipe:

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If using 'conda activate' from a batch script, change your
invocation to 'CALL conda.bat activate'.

To initialize your shell, run

    $ conda init <SHELL_NAME>

Currently supported shells are:
  - bash
  - cmd.exe
  - fish
  - tcsh
  - xonsh
  - zsh
  - powershell

See 'conda init --help' for more information and options.

I still get this error even after executing conda init cmd.exe and restarting the shell. I've also executed conda init cmd.exe with base environment active, but obtain the same results.

Using the same conda and conda-build combinations work on Linux.

Relevant conda info:

@nicoddemus please update conda-build. 3.17.7+ should be good here.

[nicoddemus]

Hi @msarahan,

Thanks for the lightning fast response.

I should have mentioned this, but I have tried to update the conda-build version to the latest one, but it fails with this message:

λ conda install conda-build=3.17.7
Collecting package metadata: done
Solving environment: failed

UnsatisfiableError: The following specifications were found to be in conflict:
  - conda-build=3.17.7
  - conda[version='>=4.6.1']
Use "conda search <package> --info" to see the dependencies for each package.

Which is strange because I'm using conda 4.6.1:

λ conda --version
conda 4.6.1

[msarahan]

bizarre. That's a new one to me. It looks like you have your own mirrors rather than using our servers. Are those mirrors up-to-date?

[nicoddemus]

Hmm they should be, they update every 2 hours:

λ conda search conda-build
...
conda-build                   3.17.7          py27_0  conda-channel/mirror-conda-forge
conda-build                   3.17.7          py36_0  conda-channel/mirror-conda-forge
conda-build                   3.17.7          py37_0  conda-channel/mirror-conda-forge
conda-build                   3.17.8          py27_0  conda-channel/mirror-conda-forge
conda-build                   3.17.8          py36_0  conda-channel/mirror-conda-forge
conda-build                   3.17.8          py37_0  conda-channel/mirror-conda-forge

Strangely enough, using the default channels to update conda and conda-build works:

λ conda install conda-build=3.17.7 -c defaults
Collecting package metadata: done
Solving environment: done

## Package Plan ##

  environment location: W:\Miniconda3

                                           Total:         2.3 MB

Even more strange, if I use conda-forge directly it also works:

conda install conda-build=3.17.7 -c conda-forge

So the "update issue" is somehow related to our mirrors.

Further investigation suggests that it is because of the order of our mirrors: the first channel is an internal channel with a custom python build (with MSVC2010), which is taking precedence and generating the conflicts:

λ conda install conda=4.6.1 conda-build=3.17.8 python=3.7.1
Solving environment: failed

UnsatisfiableError: The following specifications were found to be in conflict:
  - conda-build=3.17.8 -> enum34 -> python=2.7
  - python=3.7.1
Use "conda info <package>" to see the dependencies for each package.

Strangely I would expect the above command to work, because I believe conda should be honoring the python=3.7.1 package?

---

After managing to update to the latest conda build, indeed this solved my problem. 😅

Thanks @msarahan for nudging me into the right direction! 👍

[nicoddemus]

Writing my findings here in case it helps someone in the future.

We have two mirrors, one mirroring conda-forge (in full) and another mirroring main (with a whitelist of selected packages). Our intent is to get most of the packages from conda-forge and a few others from anaconda (specially the ones compiled with mkl support for speed).

So our channel list is:

• esss (internal packages)
• main (whitelist of selected packages)
• conda-forge (practically everything)

When trying to install the latest conda-build, I was getting this error:

λ conda install conda=4.6.1 conda-build=3.17.8 python=3.7.1
Solving environment: failed

UnsatisfiableError: The following specifications were found to be in conflict:
  - conda-build=3.17.8 -> enum34 -> python=2.7
  - python=3.7.1
Use "conda info <package>" to see the dependencies for each package.

It isn't clear which package is actually missing that would solve the requirements, so I tried a lot of things (conda info between conda-build 3.16 and 3.18 for example).

In the end the method which clearly stated which packages were missing was to add the defaults channel to the end of the channel list. Then executing the conda install command above with --dry-run, conda would show for each package from which channel it was coming from, making it clear to see which packages were missing.

In my case, it was liblief, pylibef, and libarchive. While the first two were relatively easy to notice because they were missing on conda-forge, conda-build needed a very specific build of libarchive which was not available on conda-forge.

hi @nicoddemus,

I am currently getting the exact same error message when using the command conda activate to activate an environment, though since I am new to coding I'm hoping the solution is more simple than yours was. I had just installed Git Bash and Anaconda earlier that day, and hadn't changed anything before building this new environment from the .yml file within (https://github.com/earthlab/earth-analytics-python-env).

On the windows environment use "anaconda prompt" instead of "command prompt".

Go to search.
Type "anaconda prompt" and open it.
Then type "conda activate

[cervantes-loves-ai]

most cleaner option will be

eval "$(conda shell.bash hook)"
conda activate my_env

[bboytian]

To retain a familiar bash terminal feel. I downloaded Git bash, and created a .bashrc file in /c/Users//.
And pasted this into the .bashrc. This will initialise your git bash terminal whenever you start it, it is essentially the same thing that is placed in Linux/macOS ~/.bashrc or ~/.bash_profile

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/c/Users/<user>/Anaconda3/bin/conda.exe' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/c/Users/<user>/Anaconda3/etc/profile.d/conda.sh" ]; then
        . "/c/Users/<user>/Anaconda3/etc/profile.d/conda.sh"
    else
        export PATH="/c/Users/<user>/Anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

[mone20chss]

It happened to me too, but in my case I solved the problem in this way: I moved to the Anaconda directory with the cd command and wrote the comand conda activate nameoftheenviroment.

[shanekmcbryde]

I've been attempting to deal with this issue all evening. I'm attempting to run code in the VSCode terminal and get the "Your shell has not been properly configured..." I'd like to try some of these solutions but I have no idea what "nameoftheenvironment", "my_env", "" mean. I'm assuming that these are placeholders but I don't know what to replace them with. Help please.

[mone20chss]

"nameoftheenvironment" is the name that you have asgin to your the environment.

[shanekmcbryde]

Yeah, ummm...that didn't help.

[yichangyu]

On the windows environment use "anaconda prompt" instead of "command prompt".

Go to search.
Type "anaconda prompt" and open it.
Then type "conda activate

Thanks!

[eliasberra]

For conda versions older than 4.4 the command is as follows for different types of operating systems::

source activate

For Linux and macOS OR

activate

For Windows. You will have to remove the conda keyword from the command.
