Silent installation

Silent installation of Miniconda or Anaconda can be used for deployment or testing or building services such as Travis CI and Appveyor. In silent mode, screen prompts are not shown on screen and default settings are automatically accepted.

NOTE: These instructions are written for Miniconda, but you can substitute “Anaconda” if you are using that version.

We recommend starting with the latest version of Miniconda or Anaconda. Check to be sure your version is up to date with a simple:

conda update conda

Windows

The Windows installer of Miniconda can be run in silent mode using the /S argument. The following optional arguments are supported:

  • /InstallationType=[JustMe|AllUsers], default: JustMe
  • /AddToPath=[0|1], default: 1
  • /RegisterPython=[0|1], make this the system’s default Python, default: 0 (Just me), 1 (All users)
  • /S
  • /D=<installation path>

All arguments are case-sensitive. The installation path must be the last argument and should NOT be wrapped in quotation marks. When using silent installation with /S you must also specify a destination installation path with /D.

The following command installs Miniconda for the current user without registering Python as the system’s default:

start /wait "" Miniconda4-latest-Windows-x86_64.exe /InstallationType=JustMe /RegisterPython=0 /S /D=%UserProfile%\Miniconda3

Linux and OS X

Silent installation of Miniconda for Linux and OS X is a simple as specifying the -b and -p arguments of the bash installer. The following arguments are supported:

  • -b, batch mode, no PATH modifications to ~/.bashrc
  • -p, installation prefix/path
  • -f, force installation even if prefix -p already exists

Batch mode assumes that you agree to the license agreement, and it does not edit the .bashrc or .bash_profile files.

A complete example:

wget http://repo.continuum.io/miniconda/Miniconda3-3.7.0-Linux-x86_64.sh -O ~/miniconda.sh
bash ~/miniconda.sh -b -p $HOME/miniconda
export PATH="$HOME/miniconda/bin:$PATH"

NOTE: This only sets the PATH for the current session, not permanently. Trying to use conda when conda is not in your PATH will cause errors such as “command not found”.

We recommend running source $HOME/miniconda3/bin/activate in each new bash session before using conda, which will set the PATH and run the activation scripts of your conda packages. Replace $HOME/miniconda3/bin/activate with the path to the activate script in your conda installation.

It is also possible to set the PATH permanently by adding a line to your .bashrc file such as export PATH="$HOME/miniconda3/bin:$PATH". However, this makes it possible to use conda without running the activation scripts of your conda packages, which may produce errors.
