The command pyenv global ${2-7-10}
is used to set the global version of Python in the pyenv environment to a specific version.
In this particular command, ${2-7-10}
is used as a placeholder for the desired version number. This syntax suggests that the version number can be replaced with a specific version, such as 2.7.10
, when executing the command.
To explain further, pyenv
is a popular tool used to manage multiple Python versions on a single system. It allows you to switch between different versions of Python and set a default version for your development environment.
The global
keyword in the command specifies that the selected Python version should be set as the default version for all shells, meaning it will be the version used by default when running Python scripts or using the Python interpreter.
So, when you execute pyenv global ${2-7-10}
, you are essentially telling pyenv to set the global version of Python to 2.7.10
.
