Sets the default Ruby version. You can override the default at any time |

setting the RBENV_VERSION environment variable. |

Sets the local directory default Ruby, by writing the version to a file |

named '.rbenv-version'. rbenv will search for this file up the directory |
|
|
|
tree from the current working directory each time its shims are executed, |

so this default will affect subdirectories. |

Sets the local directory-specific Ruby version by writing the version |
|
|
|
name to a file named '.rbenv-version'. |
|
|
|
|
|
|
|
When you run a Ruby command, rbenv will look for an '.rbenv-version' |
|
|
|
file in the current directory and each parent directory. If no such |
|
|
|
file is found in the tree, rbenv will use the default Ruby version |
|

specified with \`rbenv set-default', or the version specified in the |
|

RBENV_VERSION environment variable. |
