I have installed octopress but to make it run (just after booting computer up) I need to do every time :
source ~/.bash_profile
unless I do this I get an error when I run:
rake generate
Error:
bash: /usr/local/bin/rake: /usr/bin/ruby1.9.1: bad interpreter: No such file or directory
I have Ubuntu 12.0 LTS and I've gone through this question , but since am unaware of the basics of shell profiles and shell I couldn't understand the answer. Please enlighten me on that too.
The only solution on my mind seems to have a cron job scheduled for reboot so every time I reboot, it does a source ~/.bash_profile. Please suggest if there is any other solution.
Thanks!
There are a number of configuration files the shell may execute when you invoke it. By and large, they contain aliases (alternative names for commands), path-adjustments, and variable initializations; in your case, it alerts the shell to the location of a command (program) which it otherwise would not find in the PATH environmental variable.
The .bash_profile one is invoked when you start a login shell, which you probably don't. Go into your home directory (cd ~), type ls -la, and you should see a .bashrc config file. That one is invoked when you start a shell. Try opening it with your text editor of choice, and add the command you type in as the last line of the .bashrc file. This should allow you to no longer have to enter the command interactively, as it will be invoked when you start a shell.
