[--all] [package_spec [package_spec ...]]
Updates conda packages to the latest compatible version.
This command accepts a list of package names and updates them to
the latest versions that are compatible with all other packages
in the environment.
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 pre‐
vent existing packages from updating, use the --no-update-deps
option. This may force conda to install older versions of the
requested packages, and it does not prevent additional depen‐
dency packages from being installed.
If you wish to skip dependency checking altogether, use the
'--force' option. This may result in an environment with incom‐
patible packages, so this option must be used with great cau‐
tion.
OPTIONS
positional arguments:
package_spec
Packages to install or update in the conda environment.
optional arguments:
-h, --help
Show this help message and exit.
-y, --yes
Do not ask for confirmation.
--dry-run
Only display what would have been done.
-f, --force
Force install (even when package already installed).
--file FILE
Read package versions from the given file. Repeated file speci‐
fications can be passed (e.g. --file=file1 --file=file2).
--no-deps
Do not install, update, remove, or change dependencies. This
WILL lead to broken environments and inconsistent behavior. Use
at your own risk.
--only-deps
Only install dependencies.
-m, --mkdir
Create the environment directory if necessary.
-C, --use-index-cache
Use cache of channel index files, even if it has expired.
--use-local
Use locally built packages.
--offline
Offline mode, don't connect to the Internet.
--no-pin
Ignore pinned file.
-c CHANNEL, --channel CHANNEL
Additional channel to search for packages. These are URLs
searched in the order they are given (including file:// for
local directories). Then, the defaults or channels from .condarc
are searched (unless --override-channels is given). You can use
'defaults' to get the default packages for conda, and 'system'
to get the system packages, which also takes .condarc into
account. You can also use any name and the .condarc chan‐
nel_alias value will be prepended. The default channel_alias is
http://conda.anaconda.org/.
--override-channels
Do not search default or .condarc channels. Requires --channel.
-n ENVIRONMENT, --name ENVIRONMENT
Name of environment.
-p PATH, --prefix PATH
Full path to environment prefix.
-q, --quiet
Do not display progress bar.
--copy Install all packages using copies instead of hard- or soft-link‐
ing.
-k, --insecure
Allow conda to perform "insecure" SSL connections and transfers.
Equivalent to setting 'ssl_verify' to 'false'.
--update-dependencies, --update-deps
Update dependencies. Overrides the value given by `conda config
--show update_deps`.
--no-update-dependencies, --no-update-deps
Don't update dependencies. Overrides the value given by `conda
config --show update_deps`.
--channel-priority, --channel-pri, --chan-pri
Channel priority takes precedence over package version. Over‐
rides the value given by `conda config --show channel_priority`.
--no-channel-priority, --no-channel-pri, --no-chan-pri
Package version takes precedence over channel priority. Over‐
rides the value given by `conda config --show channel_priority`.
--clobber
Allow clobbering of overlapping file paths within packages, and
suppress related warnings.
--show-channel-urls
Show channel urls. Overrides the value given by `conda config
--show show_channel_urls`.
--no-show-channel-urls
Don't show channel urls. Overrides the value given by `conda
config --show show_channel_urls`.
--download-only
Solve an environment and ensure package caches are populated,
but exit prior to unlinking and linking packages into the pre‐
fix.
--json Report all output as json. Suitable for using conda programmati‐
cally.
--debug
Show debug output.
--verbose, -v
Use once for info, twice for debug, three times for trace.
--all Update all installed packages in the environment.
EXAMPLES
conda update -n myenv scipy
