No appropriate python interpreter found. Cassandra

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 -Vin 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.

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

You can refer:

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

Install your won version of python from source:

wget
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
