在macos中安装hadoop之后，我发现每次打开新的终端窗口时都会显示一个警告“-bash:hadoop:command not found”。怎么了？我该怎么修？谢谢。

以下是我的/etc/profile文件的内容：

# System-wide .profile for sh(1)

if [ -x /usr/libexec/path_helper ]; then
    eval `/usr/libexec/path_helper -s`
fi

if [ "${BASH-no}" != "no" ]; then
    [ -r /etc/bashrc ] && . /etc/bashrc
fi
