Adding a tip for how to view the Homebrew package caveats again if you skipped reading them.
Directing readers to additional next steps after installing pyenv via Homebrew.
Many advanced users who enjoy reading detailed documentation may not really think of themselves as "neckbeards", even in a jokey way, so naming this section with a simple, familiar (and easy-to-translate!) name may encourage more people to read it. :)
Correcting instructions for installing Python versions (removing "download and unpack the source").
Fixing links to #pyenv-shell, #pyenv-local, and #pyenv-global - linking them to the appropriate sections of the COMMANDS.md page.
Provide an `rbenv install` example and explanation lower down, so that
both folk that are following git install and Homebrew install will
finish at the same section and learn how to use ruby-build.
Also remove step 6 of manual install process: `rbenv rehash`. It's
unnecessary at that point, even if they already did `rbenv install`
(which rehashes automatically).
Fixes#455, closes#456
Don't suggest that they add to their `.profile` anymore because:
1. They would have to restart the desktop session for their change to be
reflected, or source the file manually;
2. An error in `.profile` may prevent logging in;
3. The `rbenv()` shell function and shell completions won't be available
in Terminal since it doesn't start bash in login mode by default.
Therefore, suggest that they use `.bashrc` instead. This will be
immediately reflected in a new Terminal tab. If bash is started in login
mode somehow, the default `.profile` is set up to source `.bashrc` anyway.
Also, don't suggest restarting the shell environment with
`exec $SHELL -l`, since we don't know what was the original mode that
their shell was started in. (OS X Terminal.app will be login mode,
Ubuntu Terminal has non-login mode by default.) Mode can be checked with:
* bash: `shopt -q login_shell`
* zsh: `[[ $options[login] = "on" ]]`
But since this is gnarly, let's just avoid it altogether and go the
easy route.
Closes#305, fixes#373, reverts #286
