编辑：我得到了安装 pip 和 pyserial 的帮助，但是 import serial 在我的项目中不起作用。在我的帖子末尾更好地解释。
我正在尝试为学校项目安装 pyserial。
我想我之前一定是搞砸了一些东西，因为我对使用终端并不熟悉。
无论如何，我尝试了很多不同的方法，但都没有奏效。当我写
> python3 -m pip search pyserial
我得到这个例外：

有人对我能做什么有建议吗？
我也下载了一个包含该软件包的 zip 文件，但我不知道如何安装它，所以我同样迷路了。
谢谢你的帮助！
多亏了良好的帮助，我认为我已经接近修复它了。我现在可以在写的时候找到 pyserial
点子列表
但是，当我尝试在 python 文件中导入它时，我得到了这个：
ImportError：没有名为“串行”的模块
除了在终端中安装它之外，我还需要做什么才能在项目中使用它？是否有可能我已经安装了它以用于 Python 2 而不是我正在使用的 Python 3？
