【解决】venv 的名字在 zsh prompt 中不显示

venv 的名字在 zsh prompt 中不显示

➜ liyongjiandeMBP.lan [/Users/liyongjian/lyj] python3 -m venv lyj_venv
➜ liyongjiandeMBP.lan [/Users/liyongjian/lyj] source ./lyj_venv/bin/activate
➜ liyongjiandeMBP.lan [/Users/liyongjian/lyj] python

我的 zsh 使用的是 robbyrussell 主题，进入到 ~/.oh-my-zsh/plugins/virtualenv

➜ liyongjiandeMBP.lan [/Users/liyongjian/.oh-my-zsh/plugins/virtualenv] git:(master) ✗ cat virtualenv.plugin.zsh
function virtualenv_prompt_info(){
[[ -n ${VIRTUAL_ENV} ]] || return
echo "${ZSH_THEME_VIRTUALENV_PREFIX:=[}${VIRTUAL_ENV:t}${ZSH_THEME_VIRTUALENV_SUFFIX:=]}"
}

# disables prompt mangling in virtual_env/bin/activate
export VIRTUAL_ENV_DISABLE_PROMPT=

将 `export VIRTUAL_ENV_DISABLE_PROMPT=1` 注释掉，然后 source ~/.zshrc

➜ liyongjiandeMBP.lan [/Users/liyongjian/lyj] python3 -m venv lyj_venv
➜ liyongjiandeMBP.lan [/Users/liyongjian/lyj] source ./lyj_venv/bin/activate
