pip、SSLException的问题
pip、SSLException的问题
提问于 2018-09-10 05:57:01
编辑:我得到了安装pip和pyserial的帮助，但导入序列在我的项目中不起作用。更好的解释在我的帖子的末尾。
我正在尝试为一个学校项目安装pyserial。
无论如何，我尝试了很多不同的方法，但都没有奏效。当我写的时候
> python3 -m pip search pyserial我得到了这个例外：

谢谢你的帮助！
多亏了大家的帮助，我想我已经接近修复它了。我现在可以在编写代码时找到pyserial。
pip列表
但是，当我尝试将其导入到python文件中时，我得到的结果是：
ImportError:没有名为'serial‘的模块
除了在终端安装之外，在项目中使用还需要做什么吗？有没有可能我安装它是为了在Python 2中使用，而不是在我正在使用的Python 3中使用？

easy_install pip如果您需要管理员权限才能运行此命令，请尝试：
sudo easy_install pip请使用以下命令来安装pyserial：
