Easy install Installation issue

When I run the following command of easy install: sudo python install.py --develop, I received the following error:

You have python 3 instead of python 2.7

In my virtual environment, i already set to python2.7:

(erpnext2) a@virtual-machine:~/erpnext$ python --version
Python 2.7.12

Why i run the benchmark it still running in python3?, as follows:

Traceback (most recent call last):
File “/usr/local/bin/bench”, line 11, in
load_entry_point(‘bench’, ‘console_scripts’, ‘bench’)()

Please advise.

What is the output of which python? Look at the symlink for python in /usr/bin.

Hi James.

The output of ‘which python’ displays me the python directory: /home/a/erpnext/erpnext2/bin/python

Then we i check the symlink in that directory, here’s wha I get
(erpnext2) a@a-virtual-machine:~/erpnext$ ls -al /home/a/erpnext/erpnext2/bin/python
lrwxrwxrwx 1 a a 9 Nov 23 04:59 /home/a/erpnext/erpnext2/bin/python -> python2.7

Seems it is pointing to python2.7. What else could i try?

That is not right. A which python should return something like this:

 /usr/bin/python

and if you then run

 ls -l /usr/bin/python

you should get something like this:

 lwrxrwxrwx 1 root root 9 Mar 16 2015 /usr/bin/python -> python2.7

if you a

 ls -al /usr/bin/python*

you will get a full listing of all the python links and executables installed on the server. If you have python 2.7, 3, 3.4 could could easily see more than one executable in the directory.

Fix the python symlink to point to python2.7 and try again.
