conda install — conda 25.7.0 documentation

conda install

Install a list of packages into a specified conda environment.

This command accepts a list of package specifications (e.g, bitarray=0.8) and installs a set of packages consistent with those specifications and compatible with the underlying environment. If full compatibility cannot be assured, an error is reported and the environment is not changed.

Conda attempts to install the newest versions of the requested packages. To accomplish this, it may update some packages that are already installed, or install additional packages. To prevent existing packages from updating, use the —freeze-installed option. This may force conda to install older versions of the requested packages, and it does not prevent additional dependency packages from being installed.

If you wish to skip dependency checking altogether, use the ‘—no-deps’ option. This may result in an environment with incompatible packages, so this option must be used with great caution.

conda can also be called with a list of explicit conda package filenames (e.g../lxml-3.2.0-py27_0.tar.bz2). Using conda in this mode implies the —no-deps option, and should likewise be used with great caution. Explicit filenames and package specifications cannot be mixed in a single command.

When using —file, only the package list from the file is used. Any name or prefix in the file (e.g. in environment.yml) is ignored; packages are installed into the target environment (-n/-p or the current environment).
