OctoPi 0.14
OctoPrint Version 1.3.8
Raspberry Pi 3

Fresh installation. Tried to install Adafruit DHT library for enclosure plugin. Followed this:

cd ~
git clone https://github.com/adafruit/Adafruit_Python_DHT.git
cd Adafruit_Python_DHT
sudo apt-get update
sudo apt-get install build-essential python-dev python-openssl
sudo python setup.py install

Last step causes this:

pi@octopi:~ $ cd Adafruit_Python_DHT
pi@octopi:~/Adafruit_Python_DHT $ sudo python setup.py install

  File "/usr/lib/python2.7/zipfile.py", line 811, in _RealGetContents
    raise BadZipfile, "File is not a zip file"
zipfile.BadZipfile: File is not a zip file

Any ideas? Can’t figure out what’s going wrong. Thanks in advance.

Try adding:

sudo apt-get install python-pip

before the:

sudo python setup.py install

Please report the problem in the Adafruit forums. I had a very similar problem with their DC Motor Hat. Adafruit needs to go through all of their software installations and make sure they work on the more recent versions of Raspbian (OctoPi).
