python - conda command will prompt error: "Bad Interpreter: No such file or directory"

Question

I'm using arch linux and I've installed Anaconda as per the instruction on the Anaconda site. When I'm attempting to run conda info --envs I get the following error:

bash: /home/lukasz/anaconda3/bin/conda: /opt/anaconda1anaconda2anaconda3/bin/python: bad interpreter: No such file or directory

I've tried looking for the directory /opt/anaconda1anaconda2anaconda3/bin/python: but it simply doesn't exist.

Furthermore, when I run python from the terminal it runs as normal with the following displayed at the top

Python 3.5.2 |Anaconda custom (64-bit)| (default, Jul  2 2016, 17:53:06) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.

for completeness my .bashrc file resembles:

#
# ~/.bashrc
#

# If not running interactively, don't do anything
[[ $- != *i* ]] && return

alias ls='ls --color=auto'
PS1='[u@h W]$ '

# added by Anaconda3 4.0.0 installer
export PATH="/home/lukasz/anaconda3/bin:$PATH"

# python startup for up keys
export PYTHONSTARTUP=$HOME/.pythonstartup

I've tried following this and making the the appropriate changes but nothing, I've also attempted to do this but there really isn't a solution posted.

I would like to try to fix this without having to remove Anaconda and reinstalling it.

Answer 1

Something must have gone wrong during the installation, I suppose. The bad interpreter means that a script is looking for an interpreter that doesn't exist - as you rightfully pointed out.

The problem is likely to be in the shebang #! statement of your conda script.

From Wikipedia: Under Unix-like operating systems, when a script with a shebang is run as a program, the program loader parses the rest of the script's initial line as an interpreter directive; the specified interpreter program is run instead, passing to it as an argument the path that was initially used when attempting to run the script.

If you run

cat ~/anaconda3/bin/conda

You will probably get the following:

#!/opt/anaconda1anaconda2anaconda3/bin/python
if __name__ == '__main__':
    import sys
    import conda.cli

    sys.exit(conda.cli.main())

Changing the first line to point a correct interpreter, i.e., changing it to:

#!/home/lukasz/anaconda3/bin/python

Should make the conda command work.

If you are sure that you installed everything properly, then I'd suggest maybe reaching out for support from the anaconda community.
