No appropriate python interpreter found. Cassandra

Question

I am a java developer and am very new to Linux and Cassandra. I am using CentOS6. I am trying to install Cassandra3.4 in the Linux machine. I have followed the steps mentioned in here.

Looks like the Linux machine already has Python installed. When I tried python -V in my putty connected to the Linux machine, I got the following output in my putty. Python 2.6.6 . I am assuming python is installed.FYKI, I have no clue how python works.

After I completed the installation process, I ran the cassandra service with the following command. /opt/cassandra/bin/cassandra -f -R &. It was all good.

Now, here comes the problem. When I run ./cqlsh I get the following error.

No appropriate python interpreter found.

I did my research and tried out a couple of options, but nothing was fruitful so far.

1. Try 1

2. Try 2

3. Try 3

4. Try 4

5. Try 5

None of the above links worked for me. Or probably I am not smart enough to understand. Any help would be much appreciated. Thanks.

Which Cassandra version you are using ? – Cavy

I am using Cassandra3.4 – Dustpan

Answer 1

I think you should try to update your Python to 2.7 version , because Cassandra 3.x requires Python 2.7

You can refer:

[http://thecpaneladmin.com/how-to-upgrade-python-on-centos/][1]

Assuming you have not changed any python configuration while installation, it should work. You can try and let us know.

Will try that and get back to you. – Dustpan

Firtsly, thanks for your answer. I followed the steps mentioned in the site you mentioned. I am stuck in this step: './configure –prefix=/usr/local' . I am getting the following error. configure: error: invalid variable name: `prefix' Any clue? – Dustpan

@Dustpan You are copypasting the command from the site , try typing it its --prefix ( two hyphens - - ) – Cavy

Answer 2

Install your won version of python from source:

wget http://python.org/ftp/python/2.7.6/Python-2.7.6.tgz

tar -xvzf Python-2.7.6.tgz

cd Python-2.7.6

./configure --prefix=/usr/local

make

make install

Now any scripts that require the alternate version should have the following shebang:

#!/usr/local/bin/python2.7

using pip:

/usr/local/bin/pip2.7

source
