# Summary: Set or show the local application-specific Ruby version
|
|
#
|
|
# Usage: rbenv local <version>
|
|
# rbenv local --unset
|
|
#
|
|
# Sets the local application-specific Ruby version by writing the
|
|
# version name to a file named `.ruby-version'.
|
|
#
|
|
# When you run a Ruby command, rbenv will look for a `.ruby-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'. A version specified with the
|
|
# `RBENV_VERSION' environment variable takes precedence over local
|
|
# and global versions.
|
|
#
|
|
# For backwards compatibility, rbenv will also read version
|
|
# specifications from `.rbenv-version' files, but a `.ruby-version'
|
|
# file in the same directory takes precedence.
|
|
#
|
|
# <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.
