![如何使用 pip3 安装 ipython?](https://linux22.com/image/1436629/%E5%A6%82%E4%BD%95%E4%BD%BF%E7%94%A8%20pip3%20%E5%AE%89%E8%A3%85%20ipython%EF%BC%9F.png)
我刚刚做了以下操作,没有任何问题:
brew install python3
pip3 install numpy
pip3 install scipy
但尝试时:
pip3 install ipython
我得到:
Exception:

为什么这不起作用?我该如何解决这些错误?
答案1
您可能没有/usr/local/bin
目录的写入权限。要解决此问题,请运行
sudo pip3 install ipython
您需要输入密码,假设您在计算机上拥有管理员权限。
答案2
您使用--user
,除非您由于某种原因以超级用户 (su) 身份安装。
pip3 install --user ipython
