pydart2 cannot be install on Ubuntu 18.04 (python3)

[larksq]

Pydart2 cannot be installed with this issue from the year of 2018. Still not solved. Pip install and make install will goes to the same problem.

Since pydart2 is now deprecated.
Is it possible to make some updates so that flappy will not rely on pydart2?

We realize this problem and we are currently working on removing pydart2 dependency. There should be an update soon.

Hi, @ffnc1020 , has this issue been solved? It seems now that pydart2 is still a dependency of flappy.

it might help if you setup pydart2 from source and switch the c++ standard to c++14 in the setup.py.
git clone https://github.com/sehoonha/pydart2.git
in setup.py line 33
CXX_FLAGS = '-Wall -msse2 -fPIC -std=c++14 -Xlinker -rpath /usr/local/lib '
and run in venv
python3 setup.py install

solved by the method above

@kexin0614 Thanks for your advice and I will try. One of the errors from my installation through pip3 shows that std::make_unique cannot be found in std namespace. According info online, make_unique is an upcoming C++14 feature and thus might not be available on some computer even if the compiler is C++11 compliant.

This works. Another error occurs:
from . import pydart2_api as papi
ImportError: cannot import name 'pydart2_api'...

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib:/usr/lib:/usr/local/lib

We managed to wrap everything in a docker file. If you guys can install that I can provide the image file later.

@huangatlas i don't know why but it seems that readme.md forgets to pip install click and pyqt5, and after i installed these packages it works...
