Conda - Silently installing a package
PythonCondaInstallation PackageMinicondaPython Problem Overview
I am trying to automate the process of setting up a development environment with pandas package using conda.
I installed conda, created and activated a dev environment. When I tried to install a package as follows, I noticed that there was a prompt to which a user had to key in Y or N (Proceed ([y]/n)?) for the installation to proceed successfully.
$ conda install pandas

How can I override these prompts so that the installation takes place silently? I tried using the -f flag but it does not seem to be existing with the conda install command.
Thanks in advance!
Python Solutions
Solution 1 - Python
Used $conda install -y pandas and it installed without any prompts (see documentation).
Solution 2 - Python
One-time Use
-y, --yes option.
# e.g. No.1
conda create -n myenv python=3.6 -y
# e.g. No.2
# install into a specific environment
conda install -n myenv requests -y
# install into the "base" env
conda install flake8 --yes
Script Use
Warning. This method confirms any type of prompt.
export CONDA_ALWAYS_YES="true"
# confirm all following "conda" commands
conda create -n myenv
conda install -n myenv requests
# ...
# Disable yes to all
unset CONDA_ALWAYS_YES
You may need to check How to activate conda env through shell script.
Environment Specific Use
Warning. This method confirms any type of prompt.
Enable "yes" to any prompt within current active env.
# enable yes to all in current env
conda config --env --set always_yes true
# disable it in current env
conda config --env --remove always_yes
Solution 3 - Python
I suggest not to pass the confirmation process.
because it always has important info regarding this installation(which package will be updated and which dependency package will be installed and which package will be downgraded)
I once corrupt my environment due to not notice the update some of the package and took a long time to figure out some package need to stay in a older version to make some other package run properly.And that confirmation details will always makes you informed and tell you where to debug once you corrupt your package environment after installation
Anyway, here is the solution. Just use -y flag :
conda install -y PACKAGE_NAME
