Laden Sie die RVM-Umgebung in Screen und ZSH

Dieses Thema hat mich schon eine Weile verrückt gemacht und ich würde gerne herausfinden, was falsch läuft. Ich benutze zshmit screenin meinem Terminal, und habe für eine Weile gewesen. Aus irgendeinem Grund wird meine Installation von RVMjedoch beim Anmelden nicht standardmäßig geladen. Ruby ist korrekt auf die von RVM (1.9.3) installierte Version eingestellt, der Rest der Umgebung wird jedoch nicht geladen:

~/Desktop => ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0]
~/Desktop => rails -v
Rails is not currently installed on this system. To get the latest version, simply type:

    $ sudo gem install rails

You can then rerun your "rails" command.
~/Desktop => rvm reload
RVM reloaded!
~/Desktop => rails -v
Rails 3.2.1

Ich habe keine Ahnung, was schief geht, und nach allem, was ich weiß, sollte nichts schief gehen. Meine screenrcDatei verwendet die Login-Shell korrekt mit shell -$SHELL, scheint jedoch keine Auswirkung zu haben (leider ist dies das einzige, was anscheinend die RVM-Installationen anderer Leute repariert hat screen, und es ist das, was in den Dokumenten vorgeschlagen wird, um sicherzustellen, dass Sie festgelegt haben , aber es scheint keinen Unterschied für mich zu machen).

Ich arbeite unter Mac OS X 10.7.3 und meine Anmeldeshell ist auf eingestellt /bin/zsh. Benutze ich nicht oh-my-zsh. Meine zshrcDatei ist wie folgt (sorry über die Länge - ich bin sicher , dass nicht alle davon relevant sind, aber ich will keine potenziell nützliche Informationen verlassen):

Am seltsamsten ist jedoch, dass [[ -s ~/.rvm/scripts/rvm ]] && source ~/.rvm/scripts/rvm && rvm reloaddie Meldung angezeigt wird, wenn ich meine RVM-Beschaffungslinie auf ändere RVM reloaded!, die Umgebung jedoch noch nicht eingerichtet ist. railswird erst erkannt, wenn ich RVM erneut lade.

Jede Hilfe dabei wäre sehr dankbar. Vielen Dank!

Nach einigem Herumbasteln wird rvmschließlich die Umgebung standardmäßig erfolgreich geladen. Ich weiß nicht genau, welcher Teil von dem, was ich getan habe, das Problem behoben hat, aber hoffentlich hilft dies jemandem.

Im Wesentlichen habe ich meine zshKonfiguration in zwei Dateien aufgeteilt: die .zshenvDatei (die von allen Programmen geladen wird) und die .zshrcDatei (die von Grafikprogrammen geladen wird). Für diejenigen, die mit der Funktionsweise nicht vertraut sind zsh, sind diese Dateien im Wesentlichen analog zu .bash_profileund .bashrc.

Hoffentlich kann dies als kleiner Leitfaden dienen, um andere zu informieren, die die gleichen Probleme haben wie ich.

Dies ist ein riesiger Hack, aber ich habe diese Zeile .bashrcgenauso eingefügt wie in .bash_profile:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function* 

Mit diesem rvm use 1.93und ähnlichen Befehlen wurde sowohl bei normalen als auch bei Bildschirmaufforderungen der rvm is not a functionFehler nicht mehr angezeigt . Solange dieses Snippet idempotent ist (dh keine negativen Auswirkungen hat, weil es zweimal oder N-mal aufgerufen wird), sollte dies in Ordnung sein. Und da es sowieso auf jeder Login-Shell aufgerufen wird, ist das wahrscheinlich wahr. Aber mal sehen, ob das der Fall ist ...
