@naoko Running the following commands helped resolve this issue for me on Ubuntu

# Used by pyrasite to inject code into a running process
sudo apt-get install gdb
 
# Used to allow pyrasite to inspect the internals of a running process
sudo apt-get install python-dbg
 
# Make sure that gdb can find debugging symbols for the virtualenv python
sudo mkdir -p /usr/lib/debug/opt/edx
sudo ln -s /usr/lib/debug/{usr,opt/edx}/bin
 
# Enable ptrace
echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope

pip install Cython
pip install pyrasite meliae urwid
