python - 无法在 MacOS : 'zsh: command not found: nvm' 上使用 nvm install

Question

我很感激这个问题已被问过几次，但没有一个答案能够帮助我。

我是在终端工作的新手，正在尝试在 MacOS Catalina 上使用 nvm 安装 Node 。我使用“brew install nvm”成功安装了 nvm，但是当我尝试运行“nvm install 10.15.0”时出现错误“zsh: command not found: nvm”。

运行 'brew info nvm' 给了我这个:

You should create NVM's working directory if it doesn't exist:

  mkdir ~/.nvm

Add the following to ~/.zshrc or your desired shell
configuration file:

  export NVM_DIR="$HOME/.nvm"
  [ -s "/usr/local/opt/nvm/nvm.sh" ] && . "/usr/local/opt/nvm/nvm.sh"  # This loads nvm
  [ -s "/usr/local/opt/nvm/etc/bash_completion.d/nvm" ] && . "/usr/local/opt/nvm/etc/bash_completion.d/nvm"  # This loads nvm bash_completion

You can set $NVM_DIR to any location, but leaving it unchanged from
/usr/local/opt/nvm will destroy any nvm-installed Node installations
upon upgrade/reinstall.

所以，我遵循了这些说明；我创建了 NVM 工作目录并将配置添加到我的/.bash_profile shell。这是使用“nano .bash_profile”运行时的 .bash_profile 文件:

# added by Anaconda3 2019.10 installer
# >>> conda init >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$(CONDA_REPORT_ERRORS=false '/Users/emilybradley/opt/anaconda3/b$
if [ $? -eq 0 ]; then
    \eval "$__conda_setup"
else
    if [ -f "/Users/emilybradley/opt/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/Users/emilybradley/opt/anaconda3/etc/profile.d/conda.sh"
        CONDA_CHANGEPS1=false conda activate base
    else
        \export PATH="/Users/emilybradley/opt/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda init <<<


# virtualenvwrapper
export WORKON_HOME=$HOME/.virtualenvs
source "$(pyenv which virtualenvwrapper.sh)"

# RabbitMQ
export PATH=/usr/local/sbin:$PATH

export NVM_DIR="$HOME/.nvm"
  [ -s "/usr/local/opt/nvm/nvm.sh" ] && . "/usr/local/opt/nvm/nvm.sh"  # This loads nvm
  [ -s "/usr/local/opt/nvm/etc/bash_completion.d/nvm" ] && . "/usr/local/opt/nvm/etc/bash_completion.d/nvm"  # This loads nvm bash_completion

我已经重新启动了终端，但 nvm install 仍然不起作用。老实说，我对 .bash_profile 文件有点困惑，想知道它是否与 PATH 有关？
