sudo apt-get install python-dev fixed it.

[Frostlock]

Same fix worked for me as well.

[maurice-schleussinger]

@savnik's solution works for both python 2.7 and python 3.

[mtcleverest]

It shows python-dev has no installation candidate. What to do next?

@mtcleverest

Have you searched for your problem?

• https://www.google.nl/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=raspberry+apt-get+install+no+candidate&*
• https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=79017

Your apt-get might be missing the repository which contains python-dev.

I am getting the following error while using iPython (Python 3.6.3 (v3.6.3:2c5fed86e0, Oct 3 2017, 00:32:08)) in a terminal window on a mac running Sierra and implementing the following example:

For convenience, we also allow you to index the dictionary with the special value 'default', which returns a dictionary mapping address families to the default gateway in each case. Thus you can get the default IPv4 gateway with

gws = netifaces.gateways()
gws['default'][netifaces.AF_INET]
('10.0.1.1', 'en0')

---

The results from this test - I tried replacing "[]" with "()" in different combinations but get errors as follows:

In [15]: gws=netifaces.gateways
In [16]: gws['default'][netifaces.AF_INET]

TypeError Traceback (most recent call last)

----> 1 gws['default'][netifaces.AF_INET]

TypeError Traceback (most recent call last)

Is there a solution to this issue?
