请添加'sudo'：'sudo pip3 install IPython' –

否！做**不**使用'sudo'和'pip'。 @cᴏʟᴅsᴘᴇᴇᴅ，我真的很惊讶听到你这样的事情。请参阅[this]（https://stackoverflow.com/questions/21055859/what-are-the-risks-of-running-sudo-pip） – mentalita

它的工作原理谢谢@COLDSPEED – sdevis

错误消息揭示了问题：您没有权限写入到文件夹，因为/usr/...是一个系统文件夹。

PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.5/dist-packages/IPython'

您需要使用sudo在全球范围内安装或只使用--user选项，安装包只为当前用户，而不是对所有的安装：

pip install ipython --user

或许更好选项是使用virtual environment，它为您隔离套件。

在安装任何软件包期间，如果出现任何权限问题/错误，请始终在安装命令之前添加sudo。因此，命令将是：

sudo pip3 install IPython
