Question

我使用命令pip3 install ipython 但得到这些错误我可能需要安装virtualenv吗？

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

Answer 1

错误消息显示问题：由于PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.5/dist-packages/IPython'是系统文件夹，因此您无权写入文件夹。

sudo

您需要使用--user全局安装或仅使用pip install ipython --user选项安装它们，该选项仅为当前用户安装软件包，而不是全部安装：

tidy

或许更好的选择是使用virtual environment为您隔离包。

Answer 2

如果在安装任何软件包期间出现任何权限问题/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

我正在尝试安装ipython但得到权限错误
