Neopixels

[alphagenius]

I am working on a project with the Neopixel jewel and I was following the instructions located here: https://learn.adafruit.com/neopixels-on ... i/software. I could not get scons & swig to install with apt-get so I had to download them and install them manually. They installed fine. Everything was smooth sailing until I got to the part about "sudo python setup.py install." When I did that, I got the following error:

swig: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory
error: command 'swig' failed with exit status

Will someone please help me fix this error?

Whatever you installed must have some difference from what gets installed via the package manager.

I could not get scons & swig to install with apt-get

What happened when you tried?

When I use the package manager to install scons and swig, I get the message that it could not locate the packages.

Did you run "sudo apt-get update" first? What OS are you using? I just ran:

Code: Select all

sudo apt-get update
sudo apt-get install swig scons

and everything installed fine on Raspbian Stretch.

I got it to work. I must have made a typo the first time I did it. Thank you for your help.
