Hi,

The package already installed on the remote host but still, it´s failing with the above error.  
[root@sejenk01 ~]# yum install pexpect  
Loaded plugins: ulninfo  
Package pexpect-2.3-11.el7.noarch already installed and latest version  
Nothing to do

Regards,  
Prathap

Ansible needs the python pexpect package.

Ok. Apologies for this because I am new to scripting and doing the first time so little confused.

Now I need to install python packages on my remote hots right ?. If yes, can I follow the below steps to install python packages?

```auto
mv pexpect-4.2.1.tar.gz /usr/local/src/
cd /usr/local/src
tar zxvf pexpect-4.2.1.tar.gz
cd pexpect-4.2.1
python setup.py install

```

```auto

```
