But when I typed `pyenv virtualenv 2.6.9 project_name`, I got this output:\r\n\r\n```\r\nUsage: pyenv virtualenv [-f|--force] [VIRTUALENV_OPTIONS] <version> <virtualenv-name>\r\n       pyenv virtualenv --version\r\n       pyenv virtualenv --help\r\n\r\n  -f/--force       Install even if the version appears to be installed already\r\n```\r\n\r\nThat tells me absolutely nothing about what's wrong with my inputs, so I spent several minutes faffing about with various attempted fixes. I eventually realized that my problem was that I hadn't run `pyenv install 2.6.9` yet. \r\n\r\nMaking it clear *why* an invocation of `pyenv virtualenv` failed is essential user feedback, and I'd very much like to see it added as soon as possible.\r\n\r\n<bountysource-plugin>\r\n---\r\nWant to back this issue? **[Post a bounty on it!](https://www.bountysource.com/issues/22280303-error-messages-need-to-be-improved?utm_campaign=plugin&utm_content=tracker%2F335155&utm_medium=issues&utm_source=github)** We accept bounties via [Bountysource](https://www.bountysource.com/?utm_campaign=plugin&utm_content=tracker%2F335155&utm_medium=issues&utm_source=github).\r\n</bountysource-plugin>"}}
