I am new to Cygwin, using it in order to learn Python. I am attempting to install Eric6 Python IDE, which requires certain packages such as PyQt5, Scintilla2, etc.
I installed python2, python3, PyQt5, pip3.6 (pip-9.0.3), and several other packages using the Cygwin setup app (setup-x86_64.exe).
When I attempt to install Eric6:
$ python3 install.py Checking dependencies Python Version: 3.6.4 Found PyQt5 Found pyuic5 Sorry, please install QScintilla2 and its PyQt5/PyQt4 wrapper. Error: cannot import name 'Qsci'
Per matzeri's answer, I found that I had missed seeing scintilla2 in the Cygwin packages list, so I installed it from there
[package: mingw64-x86_64-qscintilla2-qt5] and it appeared to install without any issues. However, I continue to get the exact same error as before when attempting to install Eric6
Sorry, please install QScintilla2 and its PyQt5/PyQt4 wrapper. Error: cannot import name 'Qsci'
I have tried rebooting both Cygwin and the local machine, with no luck.
