Python Anaconda启动spyder错误（ModuleNotFoundError）

修订：现在我得到另一个timeit错误

我正在用从anaconda发射的spyder进行编码，突然我发现了一个错误：timeit中找不到计时器，而timeit在一秒钟前一直在为我工作。然后我重新启动了anaconda并重新安装了spyder，但当我再次尝试启动spyder时，我得到了以下错误。有人能帮忙吗？我正在使用MacOS和最新版本的spyder

应用程序启动错误：应用程序spyder可能产生以下错误

您必须安装NumPy库

conda install numpy

---

谢谢，我也必须为matplotlib和scipy这样做。现在我得到一个错误，说AttributeError:module'timeit'没有属性'Timer'。尝试从timeit导入Timer导入

，然后在写入类'Timer（Timer）`之后，我想问题是您周围有一个名为
timeit.py
的文件，它干扰了IPython包中同名的模块。IPython是Spyder的附属品。
