Pracuję z Ubuntu 12.04.

To mój ~/.profile file:

# ~/.profile: executed by the command interpreter for login shells. 
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login 
# exists. 
# see /usr/share/doc/bash/examples/startup-files for examples. 
# the files are located in the bash-doc package. 

# the default umask is set in /etc/profile; for setting the umask 
# for ssh logins, install and configure the libpam-umask package. 
#umask 022 

# if running bash 
if [ -n "$BASH_VERSION" ]; then 
    # include .bashrc if it exists 
    if [ -f "$HOME/.bashrc" ]; then 
     . "$HOME/.bashrc" 
    fi 
fi 

# set PATH so it includes user's private bin if it exists 
if [ -d "$HOME/bin" ] ; then 
    PATH="$HOME/bin:$PATH" 
fi 
export PATH="$HOME/.rbenv/bin:$PATH" 
eval "$(rbenv init -)" 
eval "$(rbenv init -)" 
eval "$(rbenv init -)" 

Mam zainstalowany rubin ostatnia wersja z rbenv i gdy próbuję ruby -v uzyskać -bash: ruby: command not found

Answer 1

rbenv Potrzeby te w końcu ~/.bash_profile:

export PATH="$HOME/.rbenv/bin:$PATH" 
eval "$(rbenv init -)" 

Zastosowanie grep rbenv ~/.bash_profile aby zobaczyć czy są tam.

Jeśli nie, uruchom:

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile 
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile 
exec $SHELL -l 

i powinien być uruchomiony.

Aby uzyskać więcej informacji, zobacz kroki 2 i 3 w dokumencie the docs.

Answer 2

Uruchom env | grep PATH i upewnij się, że masz $HOME/.rbenv/bin w PATH .

Jeśli nie, dodaj to do ~/.bash_profile.

export PATH="$HOME/.rbenv/bin:$PATH"
