When activating a qiime2 2018.11 conda environment from within a bash script that has the -u option activated, q2cli's tab completion hook raises the following error message:
$HOME/miniconda3/envs/qiime2-2018.11/etc/conda/activate.d/50_activate_q2cli_tab_completion.sh: line 1: ZSH_VERSION: unbound variable
Note: the bash -u option ("nounset") raises an error when an undefined variable is attempted to be used.
Here's a minimal script to reproduce the error (tested on macOS):
#!/usr/bin/env bash
set -u
source activate qiime2-2018.11
The error message doesn't occur if -u is turned off before activating the conda environment:
#!/usr/bin/env bash
set -u
set +u
source activate qiime2-2018.11
set -u
It's probably a simple fix to how ZSH_VERSION is referenced in 50_activate_q2cli_tab_completion.sh. Just wanted to note the issue and a workaround in case anyone else runs into it. Thanks!
