I'm trying to install bern2 locally. bern2 installed successfully. when I started running, I got this error.

  • Looks like you need to update libstdc++. The answers in [this](https://stackoverflow.com/questions/72540359/glibcxx-3-4-30-not-found-for-librosa-in-conda-virtual-environment-after-tryin) question might help. – jivanf Nov 24 '22 at 07:14

it works for me that update libstdc++

sudo add-apt-repository ppa:ubuntu-toolchain-r/test 
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

check the result

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX

The reason could be that the system path is not configured correctly. Try this,

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CONDA_PREFIX/lib/
