We'll need a little bit more information. What platform are you on? How did you install lldb?

[iamanonymouscs]

I am running lldb in Ubuntu 22.04 LTS. Following is the platform information:

$ uname -a
Linux ea22053d0460 5.10.104-linuxkit #1 SMP Thu Mar 17 17:08:06 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

I installed the development branch of lldb following this website (LLVM Ubuntu nightly packages): https://apt.llvm.org/

I think it is worthy to note that my ubuntu is running inside a container.

I see the same behavior in LLDB 14 on Ubuntu 20.04 (not running in a container), installed with
bash -c "$(wget -O - https://apt.llvm.org/llvm.sh)"

I had the same situation as @nlsandler - following the steps outlined in this bug report on launchpad.net: https://bugs.launchpad.net/ubuntu/+source/llvm-defaults/+bug/1972855 solved it for me.

It appears that the issue is down to a mismatch in python paths.

I suspect OP's issue is the same as mine. lldb -P returns /usr/lib/lib/python3.8/site-packages for LLDB builds from deb http://apt.llvm.org/focal/ llvm-toolchain-focal-14 repos. It should instead return /usr/lib/llvm-14/lib/python3.8/site-packages which is where these Python dependencies are installed. Any ideas where this mistake originates?

Same here. Win10 wsl2. After updating Ubuntu from 20.04 to 22.04, I found lldb still kept version 10 so I ran apt-get -u dist-upgrade and upgraded again. lldb turned to version 14.0.0 now but came with this problem.

Thanks for the link, @tgfrerer
tldr: lldb -P prints destination, which doesn't exist; do mkdir -p /usr/lib/local/lib/python3.10 && ln -s /usr/lib/llvm-14/lib/python3.10/dist-packages /usr/lib/local/lib/python3.10/dist-packages
maybe your llvm-14 dir is located/named different🙂
