pip 的问题，SSLException [重复]

Question

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。

我想我之前一定是在安装或更改某些东西时搞砸了，因为我不太熟悉使用终端。

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

我得到了这个例外：

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。

感谢您的帮助！

多亏了很好的帮助，我想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，当我尝试将其导入 python 文件时，我得到了这个：

ImportError: 没有名为“serial”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？

Answer 1

使用以下命令在 Mac 上安装 pip：

easy_install pip

如果您需要管理员权限来运行它，请尝试：

sudo easy_install pip

使用以下命令安装pyserial：

pip install pyserial

我希望这会有所帮助。
