# Summary: Set or show the local directory-specific Ruby version
|
|
#
|
|
# Usage: rbenv local <version>
|
|
# rbenv local --unset
|
|
#
|
|
# 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 global Ruby version
|
|
# specified with `rbenv global', or the version specified in the
|
|
# RBENV_VERSION environment variable.
|
|
#
|
|
# <version> should be a string matching a Ruby version known to rbenv.
|
|
# The special version string `system' will use your default system Ruby.
|
|
# Run `rbenv versions' for a list of available Ruby versions.
