打开终端时出现Bash错误

Question

我最近使用以下命令在我的mac上安装了Ruby：

brew install rbenv ruby-build

然后我被指示输入此命令将rbenv添加到bash，以便每次终端打开时加载：

# Add rbenv to bash so that it loads every time you open a terminal
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
source ~/.bash_profile

现在，每当我打开终端时，我都会收到此错误：

-bash: /Users/pw/.bash_profile: line 1: syntax error near unexpected token `source'
-bash: /Users/pw/.bash_profile: line 1: `if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi source /Users/pw/.bash_profile'

有关如何阻止此错误显示的任何想法？

~/.bash_profile底部应该有一行说明：

if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi

这就是全部。没有提到source anything。
