Python 我需要安装"；quandl"；。但当我输入；sudo pip安装quandl“；在终端中，我得到以下错误：

然后，我尝试在终端中使用“sudopip安装加密”手动安装“加密”。然后我得到了以下错误：

eranga@eranga-Inspiron-3521:~$ sudo pip install quandl

我看了很多网站，读了很多文章，仍然无法摆脱这个错误。我对“quandl”和机器学习都是新手。因此，如果有任何详细的安装“quandl”的方法，我将不胜感激

运行：

与python社区和Mikko Ohtamaa提到的糟糕做法背道而驰。使用

将导致

重写包数据，普通用户将不再具有写入权限
