[path] command
(Experimental) Run a command given a set of requirements from a recipe or from command line.
positional arguments:
path Path to a folder containing a recipe (conanfile.py or
conanfile.txt) or to a recipe file. e.g.,
./my_project/conanfile.txt. Defaults to the current
directory when no --requires or --tool-requires is
given
command Command to run
options:
-h, --help show this help message and exit
--out-file OUT_FILE Write the output of the command to the specified file
instead of stdout.
-v [{quiet,error,warning,notice,status,verbose,debug,v,trace,vv}]
Level of detail of the output. Valid options from less
verbose to more verbose: -vquiet, -verror, -vwarning,
-vnotice, -vstatus, -v or -vverbose, -vv or -vdebug,
-vvv or -vtrace
-cc CORE_CONF, --core-conf CORE_CONF
Define core configuration, overwriting global.conf
values. E.g.: -cc core:non_interactive=True
-b BUILD, --build BUILD
Optional, specify which packages to build from source.
Combining multiple '--build' options on one command
line is allowed. Possible values: --build=never
Disallow build for all packages, use binary packages
or fail if a binary package is not found, it cannot be
combined with other '--build' options. --build=missing
Build packages from source whose binary package is not
found. --build=cascade Build packages from source that
have at least one dependency being built from source.
--build=[pattern] Build packages from source whose
package reference matches the pattern. The pattern
uses 'fnmatch' style wildcards, so '--build="*"' will
build everything from source. --build=~[pattern]
Excluded packages, which will not be built from the
source, whose package reference matches the pattern.
The pattern uses 'fnmatch' style wildcards.
--build=missing:[pattern] Build from source if a
compatible binary does not exist, only for packages
matching pattern. --build=compatible:[pattern]
(Experimental) Build from source if a compatible
binary does not exist, and the requested package is
invalid, the closest package binary following the
defined compatibility policies (method and
compatibility.py)
--requires REQUIRES Directly provide requires instead of a conanfile
--tool-requires TOOL_REQUIRES
Directly provide tool-requires instead of a conanfile
--context {host,build}
Context to use, by default both contexts are activated
if not specified
--build-require Whether the provided path is a build-require
remote arguments:
-r REMOTE, --remote REMOTE
Look in the specified remote or remotes server
-nr, --no-remote Do not use remote, resolve exclusively in the cache
-u [UPDATE], --update [UPDATE]
Will install newer versions and/or revisions in the
local cache for the given reference name, or all
references in the graph if no argument is supplied.
When using version ranges, it will install the latest
version that satisfies the range. It will update to
the latest revision for the resolved version range.
profile arguments:
-pr PROFILE, --profile PROFILE
Apply the specified profile. By default, or if
specifying -pr:h (--profile:host), it applies to the
host context. Use -pr:b (--profile:build) to specify
the build context, or -pr:a (--profile:all) to specify
both contexts at once
-pr:b PROFILE_BUILD, --profile:build PROFILE_BUILD
-pr:h PROFILE_HOST, --profile:host PROFILE_HOST
-pr:a PROFILE_ALL, --profile:all PROFILE_ALL
-o OPTIONS, --options OPTIONS
Apply the specified options. By default, or if
specifying -o:h (--options:host), it applies to the
host context. Use -o:b (--options:build) to specify
the build context, or -o:a (--options:all) to specify
both contexts at once. Example:
-o="pkg/*:with_qt=True"
-o:b OPTIONS_BUILD, --options:build OPTIONS_BUILD
-o:h OPTIONS_HOST, --options:host OPTIONS_HOST
-o:a OPTIONS_ALL, --options:all OPTIONS_ALL
-s SETTINGS, --settings SETTINGS
Apply the specified settings. By default, or if
specifying -s:h (--settings:host), it applies to the
host context. Use -s:b (--settings:build) to specify
the build context, or -s:a (--settings:all) to specify
both contexts at once. Example: -s="compiler=gcc"
-s:b SETTINGS_BUILD, --settings:build SETTINGS_BUILD
-s:h SETTINGS_HOST, --settings:host SETTINGS_HOST
-s:a SETTINGS_ALL, --settings:all SETTINGS_ALL
-c CONF, --conf CONF Apply the specified conf. By default, or if specifying
-c:h (--conf:host), it applies to the host context.
Use -c:b (--conf:build) to specify the build context,
or -c:a (--conf:all) to specify both contexts at once.
Example:
-c="tools.cmake.cmaketoolchain:generator=Xcode"
-c:b CONF_BUILD, --conf:build CONF_BUILD
-c:h CONF_HOST, --conf:host CONF_HOST
-c:a CONF_ALL, --conf:all CONF_ALL
reference arguments:
--name NAME Provide a package name if not specified in conanfile
--version VERSION Provide a package version if not specified in
conanfile
--user USER Provide a user if not specified in conanfile
--channel CHANNEL Provide a channel if not specified in conanfile
lockfile arguments:
-l LOCKFILE, --lockfile LOCKFILE
Path to a lockfile. Use --lockfile="" to avoid
automatic use of existing 'conan.lock' file
--lockfile-partial Do not raise an error if some dependency is not found
in lockfile
--lockfile-out LOCKFILE_OUT
Filename of the updated lockfile
--lockfile-clean Remove unused entries from the lockfile
--lockfile-overrides LOCKFILE_OVERRIDES
Overwrite lockfile overrides
The conan run command lets you directly execute a binary from a Conan package, automatically resolving and installing
all its dependencies. There’s no need to manually activate any environments generated by Conan: just pass the executable
to run, and Conan will activate the necessary environments and execute it.
The command can receive either a conanfile.py/conanfile.txt or have the requirements specified directly from the CLI via --requires and --tool-requires arguments.
For example, if we call a specific version of openssl we would:
$ conan run "openssl --version" --tool-requires=openssl/3.5.4
Installing and building dependencies, this might take a while...
OpenSSL 3.5.4 30 Sep 2025 (Library: OpenSSL 3.5.4 30 Sep 2025)
This command is useful when you want to execute some specific binary from any package.
Note
This command activates both the host and build contexts, so that both contexts binaries are made available at once.
In case that a package exists in both contexts, the host context binaries take precedence.
