This environment is used internally by Conda to work. The Base environmentĪfter the initial installation of Conda, a default virtual environment called baseis created. If you want to install Conda on your user, and not root, specify this when installing. To Install Conda on Linux: wget bash Anaconda-latest-Linux-x86_64.shįollow the prompts on the installer screen. Conda easily creates, saves, loads and switches between environments on your local computer. Conda installs, runs and updates packages and their dependencies. (Of course, this's all about your or my perspective).Conda is an open-source package management system and environment management system that runs on Linux.

At the end of the day, I am happy because conda makes thing simple. If conda raises Error, I know there's not, move on. y', if conda's happy to download, I know there' compatible pysam with my env. Do 'anaconda search pysam' to see if there's any pysam for my python version.:D Saying there are two approaches below: PS: I admit that I don't review the dependencies carefully when using 'conda install' because I expected conda did the work for me. May be my mindset is still treating python as 1st class: if the version is changed, the whole conda env is broken (vs it's not really harmful if I downgrade/upgrade numpy version).

Hi you're absolutely right here in term of treating Python just as other programs. Which go you want? Conda's best guess is that you want pysam, because you have explicitly asked for that, but you may not have explicitly asked for python 3.7. Maybe you would like to review those issues, comment there, and close this issue if you think those existing proposals would solve your problem.Ĭonda can do one of two things: keep python 3.7 and deny you pysam, it give you pysam and downgrade python. Issue #7688 could also be relevant here, since it suggests adding a flag that would cause installs to fail if the solution results in a downgrade of any package. There is an open issue that addresses that in a specific way: #7325. It seems that you would like Conda to treat the python package as a special case, and to default to not allowing downgrades in order to satisfy a user's install request.
