opam-uninstall(1) An alias for remove.


opam uninstall [OPTION]... [PACKAGES]...


opam uninstall is an alias for opam remove.

See opam remove --help for details.


List of package names, with an optional version or constraint, e.g `pkg', `pkg.1.0' or `pkg>=0.5'.


--color=WHEN (absent=auto)
Colorize the output. WHEN must be `always', `never' or `auto'.
Compatibility mode with OPAM 1.0
Specify user preferences for dependency solving for this run. Overrides both $OPAMCRITERIA and $OPAMUPGRADECRITERIA. For details on the supported language, and the external solvers available, see http://opam.ocaml.org/doc/Specifying_Solver_Preferences.html. A general guide to using solver preferences can be found at http://www.dicosmo.org/Articles/usercriteria.pdf. The default value is -count(down),-count(removed),-notuptodate(solution),-count(new) for upgrades, and -count(removed),-notuptodate(request),-count(down),-notuptodate(changed),-count(changed),-notuptodate(solution) otherwise.
Debug option: Save the CUDF requests sent to the solver to FILENAME-<n>.cudf.
Print debug message to stderr. This is equivalent to setting $OPAMDEBUG to "true".
Like `--debug', but allows specifying the debug level (`--debug' sets it to 1). Equivalent to setting $OPAMDEBUG to a positive integer.
Print the git version if it exists and exit.
Do not install base packages (useful for testing purposes). This is equivalent to setting $OPAMNOBASEPACKAGES to a non-empty string.
OPAM will replace itself with a newer binary found at OPAMROOT/opam if present. This disables this behaviour.
-q, --quiet
Be quiet when installing a new compiler.
--root=ROOT (absent=~/.opam)
Use ROOT as the current root path. This is equivalent to setting $OPAMROOT to ROOT.
Make sure nothing will be automatically updated or rewritten. Useful for calling from completion scripts, for example. Will fail whenever such an operation is needed ; also avoids waiting for locks, skips interactive questions and overrides the OPAMDEBUG variable.
Specify the name of the external dependency solver. The default value is aspcud
Fail whenever an error is found in a package definition or a configuration file. The default is to continue silently if possible.
Use SWITCH as the current compiler switch. This is equivalent to setting $OPAMSWITCH to SWITCH.
--use-internal-solver, --no-aspcud
Force use of internal heuristics, even if an external solver is available.
-v, --verbose
Be more verbose. Show output of all sub-commands. This is equivalent to setting $OPAMVERBOSE to "true".
-y, --yes
Disable interactive mode and answer yes to all questions that would otherwise be asked to the user. This is equivalent to setting $OPAMYES to "true".


-a, --auto-remove
Remove all the packages which have not been explicitly installed and which are not necessary anymore. It is possible to prevent the removal of an already-installed package by running opam install <pkg>. This flag can also be set using the $OPAMAUTOREMOVE configuration variable.
-b, --keep-build-dir
Keep the build directory. This is equivalent to setting $OPAMKEEPBUILDDIR to "true".
-d, --build-doc
Build the package documentation. This is equivalent to setting $OPAMBUILDDOC to "true".
Simulate the command, but don't actually perform any changes.
-e TAGS, --external=TAGS
Display the external packages associated to the given tags.
This option registers the actions into the OPAM database, without actually performing them. WARNING: This option is dangerous and likely to break your OPAM environment. You probably want `--dry-run'. You've been warned.
Execute the remove commands of given packages directly, even if they are not considered installed by OPAM.
--help[=FMT] (default=pager)
Show this help in format FMT (pager, plain or groff).
-j JOBS, --jobs=JOBS
Set the maximal number of concurrent jobs to use. You can also set it using the $OPAMJOBS environment variable.
Save the result output of an OPAM run in a computer-readable file
-m MAKE, --make=MAKE
Use MAKE as the default 'make' command.
Do not verify the checksum of downloaded archives.This is equivalent to setting $OPAMNOCHECKSUMS to "true".
Reject the installation of packages that don't provide a checksum for the upstream archives. This is equivalent to setting $OPAMREQUIRECHECKSUMS to "true".
Call the solver and display the actions. Don't perform any changes.
-t, --build-test
Build and run the package unit-tests. This is equivalent to setting $OPAMBUILDTEST to "true".
Show version information.
