Sometimes packages will not install as wanted (resulting in import errors, Anaconda Navigator is not behaving as expected or does not start up at all. This page summarizes remedies for such problems.
Conda environment creation never finishes#
Phenomenon: creating a conda environment with and environment file (
conda env create -f environment.yml) results in quasi-eternal loading without the environment being installed even after several hours.
Fix: Before creating the environment, set the installation priority to strict (answer adapted from https://stackoverflow.com/questions/63734508/stuck-at-solving-environment-on-anaconda):
conda config --set channel_priority strict
Conda package installation fails#
Phenomenon: Installation of a Python library or package through Anaconda Prompt fails.
Fix: Several reason may cause that installing new packages fails in Anaconda Prompt or Linux / macOS Terminal:
Make sure to close all Python-dependent applications (e.g., Jupyter or PyCharm) before installing.
Conflict solving activates:
Wait until conflicts are parsed (and solved)
conda update conda
conda update anaconda
Restart Terminal or Anaconda Prompt
Try to re-install the package prompted.
Large storage size of Anaconda#
The Anaconda base environment comes with many pre-installed packages and can be very storage intensive in the order of many gigabytes. Every new environment that is produced can take the same size and multiple conda environments may jam your hard disk. Again, there are some solutions:
Create light-weight environments with Miniconda.
Clean tarballs an unnecessary package installation files with Anaconda Prompt or Linux / macOS Terminal:
conda clean --all(read more in the developer’s docs).
conda clean -tipsy
Cannot find … path#
In Anaconda Prompt or Linux / macOS Terminal run
conda init and restart the application.
