# What Should I Do If Error "command ´gcc´ failed with exit status 1" Occurs During PIP-based Software Installation

#### Symptom

When installing the Python library software, you need to configure the PIP source. Take the official image source as an example:

    [root@test home]# cat /root/.pip/pip.conf
    [global]
    index-url = https://pypi.python.org/simple
    trusted-host = pypi.python.org

During the installation, the system displays the message "command ´gcc´ failed with exit status 1". However, GCC has been installed by running the yum command before the Python library software is installed using the PIP.

#### Possible Causes

openssl-devel is not supported.

#### Solution

The following operations use psutil as an example:

1. Run the following command to install openssl-devel:

   yum install gcc libffi-devel python-devel openssl-devel -y

2. Use PIP to install the Python library software again. The error message is cleared.
