无法在MacOS上使用nvm安装：'zsh:未找到命令: nvm‘

Question

我很感谢这个问题被问了几次，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上安装带有nvm的节点。我使用'brew install nvm‘成功安装了nvm，但当我尝试运行'nvm install 10.15.0’时，我收到错误'zsh: command not found: nvm‘。

运行'brew info nvm‘得到以下结果：

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.

因此，我按照以下说明操作；我创建了NVM工作目录，并将配置添加到我的/.bash_profile外壳中。下面是我的.bash_profile文件，当使用'nano .bash_profile‘运行时：

# 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

我重新启动了终端，但nvm安装仍然不起作用。老实说，我对.bash_profile文件有点困惑，不知道它是不是和路径有关？
