我正在尝试安装 ipython 但出现权限错误

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？

Exception:

Answer 1

错误消息揭示了问题：您无权写入该文件夹，因为 /usr/... 是系统文件夹。

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

您需要使用 sudo 进行全局安装或仅使用 --user 选项安装它们，该选项仅为当前用户而非所有用户安装软件包：

pip install ipython --user

或者更好的选择是使用 virtual environment 为您隔离包。

Answer 2

只要在安装任何软件包期间存在任何权限 issues/error，请始终在安装命令之前添加 sudo。因此命令将是：

sudo pip3 install IPython
