Problem description

It works in normal shell. However, it fails in tmux 3.1 environment. It report ERROR: Failed to initialize `curses` (curs_set() returned ERR)

I have tried the solution here.

sudo apt install python3-dev python3-pip /usr/bin/python3`` -m pip install --user nvitop ～/.local/bin/nvitop

But it produced the same issue, no matter in the conda environment or not. It only differs when using tmux or not.

Hi @slacklife, can you try to set:

set -g default-terminal "tmux-256color"
set -g utf8 on

in your tmux.conf? Then you need to reload your tmux configuration.

slacklife commented 11 months ago

Thanks for your comment, but it didn't work. set -g utf8 on is for an old version of tmux. They were set in a way so they don't error in newer versions. Please refer to here

set -g default-terminal "tmux-256color" is my default setting in my .tmux.conf

Are there any other solutions to solve my problem?

XuehaiPan commented 11 months ago

@slacklife Do you set your TERM environment variable correctly in your tmux shell? For example:

export TERM="xterm-256color"
export LC_ALL="en_US.UTF-8"

slacklife commented 11 months ago

It works magically! Many thanks! Nvitop is a great tool!

XuehaiPan commented 11 months ago

It works magically!

Glad to hear that. You could put these in your shell profile (e.g., ~/.bashrc, ~/.zshrc) to automatically set these variables on startup.

export TERM="xterm-256color"
export LC_ALL="en_US.UTF-8"
