I tried to install the python 2.7.3 on Linux box and then created alias in my local .bash_profile
as below:
alias python='/opt/python2.7.3/bin/python'
alias python2.7.3='/opt/python2.7.3/bin/python'
PATH=$PATH:$HOME/bin:/opt/python2.7.3/bin
then run the command source .bash_profile
to flush out all the update. but later I found the path was actually wrong and tried to correct it to the right one:
alias python='/opt/python2.7.3/bin/python2.7'
PATH=$PATH:$HOME/bin:/opt/python2.7.3/bin/python2.7
but when I export the path, it still has the wrong directory included though it does have the right one appended to the end. how I can get rid of the wrong directory from path totally?
/etc/environment
file and then log out and log in./opt/python2.7.3/bin/python2.7
in your$PATH
.$PATH
should only contain directories.
