目前我正在使用 macOS Catalina，但是这对于几个版本是相同的。

在/etc/zprofile（或/etc/profile在旧版本上使用 bash 时）我默认有这样的内容：

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

另外，我在/etc/paths.d/android. 内容是

/Users/$USER/Library/Android/sdk/platform-tools
/Users/$USER/Library/Android/sdk/tools
/Users/$USER/Library/Android/sdk/tools/bin

但是，当我启动终端时，终端无法在这些文件夹中找到我的二进制文件：

zsh: command not found: adb

不知道为什么，但解决方法是复制路径帮助行如下？

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

所以，这是我的问题，为什么会发生这种情况以及这种解决方法实际上是如何工作的？

我对解决方法感到无聊，因为它只是在每次更新时都被删除。
