Following the guideline on 'How To Setup Your Own Computer' @
https://developer.cisco.com/learning/modules/intro-to-aci/sbx-intro-aci-02_programmability-options/step/2,
came-up with an issue, as per Title, when installing ACI Toolkit after git clone https://github.com/datacenter/acitoolkit.git
cd acitoolkit
python setup.py install

You need to install python-dev package first.  For ubuntu/debian you can install it using apt:

sudo apt-get install python-dev 

sudo apt-get install python3-dev

Since the lab was verified with Python 3.7.5 on CentOS, MAC OS and Windows. So I followed the CentOS Sample Setup Instructions Example

• Standard Development Tools
  1. sudo yum -y groupinstall development
• Python 3.7.5
  1. sudo yum -y install gcc
  2. sudo yum -y install wget
  3. sudo wget https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz
  4. sudo tar xzf Python-3.7.5.tgz
  5. cd Python-3.7.5
  6. sudo ./configure --enable-optimizations
  7. sudo make altinstal

BTW the problem comes during the setup.py install when decision is made for py-radix 0.10.0 (Downloaded from https://files.pythonhosted.org) but py-radix-0.10.0/setup.py comes up with fatal error:

Python.h: No such file or directory

For apt (Ubuntu, Debian...):

sudo apt-get install python-dev   # for python2.x installs
sudo apt-get install python3-dev  # for python3.x installs

For yum (CentOS, RHEL...):

sudo yum install python-devel   # for python2.x installs
sudo yum install python3-devel   # for python3.x installs

For dnf (Fedora...):

sudo dnf install python2-devel  # for python2.x installs
sudo dnf install python3-devel  # for python3.x installs

For zypper (openSUSE...):

sudo zypper in python-devel   # for python2.x installs
sudo zypper in python3-devel  # for python3.x installs

For apk (Alpine...):

# This is a departure from the normal Alpine naming
# scheme, which uses py2- and py3- prefixes
sudo apk add python2-dev  # for python2.x installs
sudo apk add python3-dev  # for python3.x installs

For apt-cyg (Cygwin...):

apt-cyg install python-devel   # for python2.x installs
apt-cyg install python3-devel  # for python3.x installs

Thanks it went through!

So it has nothing to do with earlier step in the procedure under 'Pull Down Sample Code and Prep Python Environment' where py-radix could not be installed as 'pip install -r requirements.txt' errored out with exit status 1, earlier in the list of requirement.txt, at flask-bootstrap?  

If this is not relevant and earlier 3.7 version of python3 devel is not an issue for the lab, this is acceptable solution then

[omz]

Did you use?

sudo yum install python3-devel

python3-devel contains Libraries and header files needed for Python development.

If .. py-radix could not be installed as 'pip install -r requirements.txt' errored out with exit status 1 .. did it fail to build? gcc error? aci toolkit install failed as it couldn't find the python.h file. These .h files are part of python3-devel

Most of the time these are dependency-issues. Python.h is used by GNU Compiler Collection (gcc) to build applications. You need to install a package called python-dev for building Python modules, extending the Python interpreter or embedding Python in applications. You encounter "Python.h: No such file or directory" error while trying to build a shared library using the file extension of another language ( e.g. 'C' ). If you are trying to build a shared library using the file extension of another language, you need to install the correct development version of Python.

Reason for this error:

• You haven't properly installed the header files and static libraries for python dev.
• Also, sometimes include files might not be default in the include path.

How to solve this error:

• Install the missing files and libraries.
• Include Path and Library.
• Finally, Compile it.
