II. Creating self-contained EBCLI installation
==============================================
./bundled_installer: line 51: /Users/tomslot/.pyenv/versions/3.7.2/bin/python: No such file or directory
./bundled_installer: line 28: echo_with_indentation: command not found

Suggested workaround (installing zlib and setting CFLAGS) does not work for me.

python3 ebcli_installer.py
