Install Anaconda or Miniconda from here https://docs.conda.io/projects/conda/en/latest/user-guide/install/macos.html
Create a conda environment in which you will install QGIS. In this example we call it conda_qgis
.
> conda create -n conda_qgis
> conda activate conda_qgis
Install QGIS into the environment:
> conda install qgis
This will install the latest available version of QGIS. If you need a specific version, you can see the available versions by executing conda search qgis
.
Now you should be able to just run
> qgis
But because of this issue QGIS may not show its GUI.
If QGIS doesn´t open, you can fix it by adding an environment variable. But you don´t want to manually add it every time you start QGIS. Do this instead:
First figure out where the files for your environment conda_qgis
is located. Run
> conda info
and look for active env location
in the output. In my case the path is /Users/asger/opt/miniconda3/envs/conda_qgis
.
Now open the file [YourCondaEnv]/etc/conda/activate.d/qgis-activate.sh
and add this line at the end of the file
export QT_MAC_WANTS_LAYER=1
To be nice we also open this file [YourCondaEnv]/etc/conda/deactivate.d/qgis-deactivate.sh
and add this line at the end
unset QT_MAC_WANTS_LAYER
From now on you should be able to open QGIS with a working GUI by executing
> conda activate conda_qgis
> qgis
One of the cool things about having a conda based QGIS is that it uses the conda python interpreter. That means that you can just install python modules in your qgis conda environment and they will be available to you in QGIS python.
For example the current QGIS from conda complains that lxml
is not available. This is easily fixed by
> conda activate conda_qgis
> conda install lxml
Which will install lxml
in the environment and it will then be available for QGIS.
Thank you to the author!! It was surprisingly hard finding directions like these.
For people doing a fresh install, running
conda search qgis
may not return any results. That means runningconda install qgis
won't work either. What follows helped me, although I don't use conda in my day to day so an expert can chime in with the corrected syntax if they'd like.If
conda install qgis
complains nothing is found, you can run the following commands to add addition channels to check for packages:If you want to install a specific version of qgis you can find it in
conda search qgis
now as mentioned.Your command for installing it may have syntax like:
conda install qgis=3.34.6=py39h4cc71a7_1 -c conda-forge
