Mycroft Skills Manager

Mycroft Skills Manager (msm) is a command line tool used to add, manage and remove Skills on any Mycroft installation.
Mycroft Skills Manager (MSM) is a command line tool used to add, manage and remove Skills on any Mycroft installation. It can install any Skill listed on the Mycroft Skills Repository or from any Github repository. msm is a handy tool for Developers and those who may frequently reconfigure, install and uninstall Skills.
Using Mycroft Skills Manager
msm has recently been rewritten in Python (msm was previously a bash script). In order to use msm, you will first need to enter the Mycroft virtual environment, venv, using the following command:
mycroft-core$ source .venv/bin/activate
(.venv) [email protected]:~/mycroft-core$
If you are using a Picroft or Mark 1 Device, you can activate the .venv using the command:
mycroft-core$ source /opt/venvs/mycroft-core/bin/activate
You can then run msm:
(.venv) [email protected]:~/mycroft-core$ msm update
To see a list of all the available msm commands, type msm -h:
(.venv) [email protected]:~/mycroft-core$ msm -h

msm errors
The deprecated version of msm had several error codes. Instead, this version relies on standard Python errors.
Here are some common errors, what they mean, and how to resolve them.
Git authentication failed
ERROR - Error running update_skill on skill-radio-rne: GitException(Git command failed: GitCommandError(['git', 'fetch'], 128, b"remote: Invalid username or password.nfatal: Authentication failed for 'https://github.com/ChrisFernandez/skill-radio-rne/'", b''))
This error usually means that the GitHub repository for the Skill no longer exists, or has moved. Remove the Skill using msm remove [Skill Name] and then install a new Skill.
Uncommitted changes
ERROR - Error running update_skill on TranslateSkill: SkillModified(Uncommitted changes:
     M requirements.sh
)
This error usually means that there is a difference between the Skill on the Device and the Skill's GitHub repo. Try re-installing the Skill.
Git command error - not something we can merge
ERROR - Error running update_skill on skill-malibu-stacy: GitException(Git command failed: GitCommandError(['git', 'merge', '--ff-only', 'origin/HEAD'], 1, b'merge: origin/HEAD - not something we can merge', b''))
This error usually means that there is no remote url defined for the Git repository (ie. named origin - which is the default name of a remote url). This often happens during Skill development when git init is run without defining a remote url. To resolve this error, add a remote url using the command git remote add origin https://github.com/yourGitHubUsername/yourrepo.git.
Git command error - failed to update repo
WARNING - Failed to update repo: GitException(Git command failed: GitCommandError(['git', 'config', 'remote.origin.url', 'https://github.com/MycroftAI/mycroft-skills'], 255, b'error: could not lock config file .git/config: Permission denied', b''))
This error usually means that the filesystem permissions of the Skill are incorrect. Manually check, and if necessary, resolve them.

Other techniques to resolve Skill installation dependencies
Forcing the re-installation of dependencies
If you're still running into trouble with dependencies, which can happen during Skill Authoring, there are some other techniques available.
To trigger a pip re-installing Skill dependencies, do the following:
Remove the /home/mycroft/.mycroft/.mycroft-skill file
Remove the /opt/mycroft/skills/.msm file
Restart the mycroft-skills service by using the command sudo service mycroft-skills restart
This will force both a Skills update and the re-installation of dependencies when the mycroft-skills service is re-started.
You can also use the utility mycroft-pip which will install dependencies into the Mycroft virtual environment without activation (ie. the 'activate' command). Use mycroft-pip as you would regular pip for installing Python libraries on which your Skill depends.
