The terminal in PyCharm Community Edition 2020.1 throws a “Cannot open local terminal” error. To fix the error, re-compile libpty.so for the 64bit ARM architecture and the Raspbian “Buster” operating system.

/opt/pycharm-community-2020.1/lib/pty4j-native/linux/x86/libpty.so
is not compiled for AARCH64 (64bit ARM) and must be exchanged against
a natively compiled one:

1. Clone https://github.com/JetBrains/pty4j.git
2. In directory pty4j/native compile like shown:
   1. gcc -fPIC -c *.c
   2. gcc -shared -o libpty.so *.o
   3. Copy the newly compiled libpty.so to
      /opt/pycharm-community-2020.1/lib/pty4j-native/linux/x86/libpty.so
