Answer : The graphviz conda package is no Python package. It simply puts the graphviz files into your virtual env's Library/ directory. Look e.g. for dot.exe in the Library/bin/ directory. To install the `graphviz` **Python package**, you can use `pip`: `conda install pip` and `pip install graphviz`. Always prefer conda packages if they are available over pip packages. Search for the package you need (`conda search pkgxy`) and then install it (`conda install pkgxy`). If it is not available, you can always build your own conda packages or you can try anaconda.org for user-built packages. Update : There exists now a python-graphviz package at Anaconda.org which contains the Python interface for the graphviz tool. Simply install it with conda install python-graphviz . (Thanks to wedran and g-kaklam for posting this solution and to endolith for notifying me). On conda: First install conda install graphviz Then the python-library for graphviz python-graphviz ...

Answer : Currently, the latest version nodejs 14.x requires icu>=65 which is not yet globally available across conda-forge packages. Therefore it can be installed into a new environment with conda create -n new_env_name -c conda-forge nodejs , but most likely will raise package conflicts in existing environments. conda install node-js -c conda-forge installing the very old version 6.13.1 seems to be a solver problem. conda install nodejs -c conda-forge --repodata-fn=repodata.json will install a more current version: nodejs-13.x. Alternative workaround is to use mamba as a conda replacement. Credits go to Wolf Vollprecht. Here's my workaround: I installed nodejs for Mac from the .pkg file from the offical site and then every time I update packages in my conda environments, I force remove the nodejs version conda installs with: conda uninstall --force nodejs and then go about using the environment as if it had nodejs installed. That way when any other package need...
