ZSH version detection broken (use user shell to check for zsh & version)

[eproxus]

The following notice is given when running rvm get head even though the Zsh version is correct (on OS X):

Upgrade Notes:


  * WARNING: In case of using Zsh, version 4.3.12 / 5.0.0+ is recommended, you have 4.3.11, errors to be expected.

  * No new notes to display.

RVM reloaded!

$ which zsh
/usr/local/bin/zsh
$ echo $ZSH_VERSION
5.0.2

[mpapis]

can you run: which -a zsh

[eproxus]

» which -a zsh
/usr/local/bin/zsh
/bin/zsh
/usr/local/bin/zsh

[mpapis]

has to be the /bin/zsh version could you confirm?

[eproxus]

Yup:

» /bin/zsh
» echo $ZSH_VERSION
4.3.11

[mpapis]

please check with rvm get head and rvm notes

[eproxus]

rvm get head now doesn't show any notice anymore. Nice work, thanks!

I just did \curl -L https://get.rvm.io | bash -s stable --rails --autolibs=enable and also got * WARNING: In case of using Zsh, version 4.3.12 / 5.0.0+ is recommended, you have 4.3.11, errors to be expected. I'm setting up a new mac and so far have installed Xcode (and the Command Line Tools) and Homebrew, haven't installed Zsh afaik.

Should I have installed Zsh before rvm?

I have the full log if you'd like it, but not sure what the following are:

?

stty: stdin isn't a terminal

Please can you let me know what the above logs mean and if you have any further advice. 🎱

[mpapis]

@simonowendesign as the first message says In case of using Zsh - so it matters only if you explicitly want to use Zsh - if unsure - means you do not want. as for rest of the messages they look harmless, except stty: stdin isn't a terminal - but for that open a new ticket with full log, not just single line of the output.

[s10wen]

Cool, thanks, new ticket = #2043.

After digging around in Finder I found /usr/lib/zsh/4.3.11 so looks like I'm on the wrong version, although I'm not sure where zsh came from (any ideas?). On my previous machine I threw a bunch of stuff together and got a load of nice stuff up and running: http://simonowendesign.co.uk/blog/2012/12/02/mother-effing-dotfiles/

This time I'm trying to get to grips with it all and find out what I'm actually doing 😄

[mpapis]

let me rephrase, Zsh and especially OH-MY-ZSH do not bring much, most of the things can be done also in bash, which is more stable and does not break something so often like zsh

[s10wen]

So as I somehow have Zsh should I delete it (if so what's the best way?) and run \curl -L https://get.rvm.io | bash -s stable --rails --autolibs=enable again?

[mpapis]

just ignore it

[eproxus]

OS X comes with Zsh preinstalled. I think this warning should only be issued if the user actually uses Zsh.

[mpapis]

there is no way to detect if user uses Zsh, the warning is displayed from within bash script, you can tell only if Zsh is used while the script is executing in Zsh.

[s10wen]

Cool, thanks for clarifying 🎩

[eproxus]

On OS X you can find out with:

» dscl localhost -read /Local/Default/Users/<USERNAME> shell
dsAttrTypeNative:shell: /usr/local/bin/zsh

On Linux, it should be even easier (check '/etc/passwd').

[s10wen]

dscl localhost -read /Local/Default/Users/simonowen shell gave me this if it's any help.

dsAttrTypeNative:shell: /bin/bash

[mpapis]

please let me know if there are any issues with the new code

[jhogendorn]

I'm experiencing this issue currently, even after running rvm get head. My circumstances are exactly the same as the OP. Not sure what information is relevant to provide to debug? RVM in general seems to behave oddly on my setup, as if it is not loading my environment.

[mpapis]

start with giving me:

echo $USER
echo $SHELL
which -a zsh
dscl localhost -read /Local/Default/Users/$USER shell

[jhogendorn]

Wow, speedy response. Fantastic. Here we go:

% echo $USER
jhogendorn
% echo $SHELL
/bin/bash
% which -a zsh
/usr/local/bin/zsh
/bin/zsh
% dscl localhost -read /Local/Default/Users/$USER shell
dsAttrTypeNative:shell: /bin/zsh

[mpapis]

so the shell you are running is /bin/zsh what version is it?

[jhogendorn]

Ok, so it seem's I answered my own question in a way with that last command, (thanks @mpapis!)

I was not running the shell I believed I was running, for shame etc. I fixed that on OS X by doing this:

brew install zsh
echo "/usr/local/bin/zsh" | sudo tee -a /etc/shells
chsh -s /usr/local/bin/zsh

Thanks for the heads up @mpapis, running rvm get head after this showed no issues.

[anthonybrown]

I seem to having a similar problem with rvm.
After rvm get head and rvm notes,
this is what I got:

Not sure what I did?
It was working fine before and I wanted to make sure my programs come from homebrew installed software
I did this echo export PATH="/usr/local/bin:$PATH" >> ~/.zshrc
I tried deleted what it did, but it's not working

[anthonybrown]

Would updating the shell in /bin/zsh fix it?

[mpapis]

@anthonybrown this is different error, please open a new issue, also are you aware that ruby 1.9.1 is no more maintained, you should try rather ruby 1.9.3 but as it's losing maintenance with end of this year, so better use ruby 2.0.0, or if it is a new app - 2.1.0 (it's preview2, but will be released in 2 weeks)

[anthonybrown]

Okay, thanks @mpapis
I was just testing to see if rvm still worked after
the #$@* up
