Los comandos Bash no funcionan en Mac

Hola, abro la ventana de mi terminal en Mac Os 10.6.8 mientras intento actualizar mi Ruby a 1.9.3 y el terminal me da esta respuesta inmediatamente cuando lo abro:

-bash: export: /Library/Frameworks/Python.framework/Versions/Current/bin': not a valid identifier 
-bash: export:/Library/Frameworks/Python.framework/Versions/2.7/bin': not a valid identifier
-bash: export: /Library/Frameworks/Python.framework/Versions/Current/bin': not a valid identifier 
-bash: export:/Library/Frameworks/Python.framework/Versions/Current/bin': not a valid identifier 
-bash: export: /usr/bin': not a valid identifier 
-bash: export:/bin': not a valid identifier 
-bash: export: /usr/sbin': not a valid identifier 
-bash: export:/sbin': not a valid identifier 
-bash: export: /usr/local/bin': not a valid identifier 
-bash: export:/usr/local/git/bin': not a valid identifier 
-bash: export: /usr/X11/bin': not a valid identifier 
-bash: export:/Users/oskarniburski/.rvm/bin': not a valid identifier 
-bash: export: /usr/X11R6/bin': not a valid identifier 
-bash: export:/Library/Frameworks/Python.framework/Versions/Current/bin': not a valid identifier 
-bash: export: /Library/Frameworks/Python.framework/Versions/2.7/bin': not a valid identifier 
-bash: export:/Library/Frameworks/Python.framework/Versions/Current/bin': not a valid identifier 
-bash: export: /Library/Frameworks/Python.framework/Versions/Current/bin': not a valid identifier 
-bash: export:/usr/bin': not a valid identifier 
-bash: export: /bin': not a valid identifier

-bash: export: /Users/oskarniburski/.rvm/bin': not a valid identifier 
-bash: export:/usr/X11R6/bin': not a valid identifier

Intenté cambiar mi camino pero no funcionó. No estoy seguro de cómo solucionar este problema y he estado leyendo un montón de foros. ¿Algunas ideas?

Aquí está el bash_profile:

$ /bin/cat ~/.bash_profile

# Setting PATH for MacPython 2.5
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/Current/bin:${PATH}"
export PATH

# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/Current/bin:${PATH}"
export PATH

# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH

export PATH

export PATH

Bien, el problema principal aquí era que tenía espacios separando las entradas del directorio en su $PATHy que tenía estos espacios en variables sin comillas que confundían bash.

Lo que quería hacer en este caso era agregar un directorio a su ruta. La sintaxis correcta es PATH="/foo:/bar/baz:$PATH. Agregar $PATHal final significa que su valor actual se agregará al final de la variable, de esa manera no sobrescribirá lo que ya estaba allí. Los directorios $PATHse leen en orden, así que agréguelo al principio si desea que se busquen los nuevos directorios al final: PATH="$PATH:/foo:/bar".

Otro problema era que tenías muchas rutas duplicadas. Puedes encontrarlos ejecutando

$ echo $PATH | perl -pne 's/:/\n/g' | sort | uniq -d
/bin
/Library/Frameworks/Python.framework/Versions/2.7/bin
/Library/Frameworks/Python.framework/Versions/3.3/bin
/Library/Frameworks/Python.framework/Versions/Current/bin
/sbin
/usr/bin
/usr/local/bin
/usr/sbin

Finalmente, estabas exportando $PATHvarias veces, lo cual no tiene sentido. Eliminé todos los duplicados, arreglé tu sintaxis y terminé con esto:

# Setting PATH for MacPython 2.5
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/Current/bin:${PATH}"

# Setting PATH for Python 2.7
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"

# Setting PATH for Python 3.3
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.3/bin:${PATH}"

# Load RVM into a shell session *as a function*
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" 
PATH="/usr/local/git/bin:/usr/X11/bin:/Users/oskarniburski/.rvm/bin:/usr/X11R6/bin:$PATH"

##
# Your previous /Users/oskarniburski/.bash_profile file was backed up 
# as /Users/oskarniburski/.bash_profile.macports-saved_2013-09-26_at_17:32:30
##

# MacPorts Installer addition on 2013-09-26_at_17:32:30: adding an appropriate PATH 
# variable for use with MacPorts.
export PATH="/opt/local/bin:/opt/local/sbin:$PATH"

# Finished adapting your PATH environment variable for use with MacPorts.

Copie ese archivo, abra su terminal y ejecute estos comandos:

/bin/cp ~/.bash_profile ~/bash_profile.bad
/bin/cat > ~/.bash_profile

El primero hará una copia de seguridad de tu actual ~/.bash_profile(por si acaso). El segundo parecerá no hacer nada pero se habrá abierto ~/.bash_profilepara escritura. Simplemente pegue lo que di arriba directamente en la terminal, luego presione Entery luego CtrlC. Eso debería hacer que todo vuelva a la normalidad.

NOTA: Estabas especificando /bin, /sbiny /usr/binen /usr/local/bintu .bash_profile. Es casi seguro que ya estén en su cuenta $PATHy no es necesario agregarlos. Si faltan ( echo $PATHpara ver el valor actual), simplemente agréguelos usando la sintaxis que describí anteriormente.
