conda更新ipykernel -v

产生以下响应。通过anaconda提示符在任何软件包上进行任何更新或安装都是相同的。以管理员身份运行。

另一方面，IDLE和pip往往更易于使用，但我宁愿anaconda进行工作。

我尝试过“全部清除conda”和“全部清除conda”。

为解决此问题，我卸载了现有的python 3.7和anaconda。我重新安装了anaconda，但有一个不同之处。

在Anaconda安装过程中，我将Anaconda注册为默认的Python 3.7。这样，Visual Studio，PyDev和其他程序可以自动将Anaconda检测为要使用的主要版本。

问题与此类似： Running setup.py install for fbprophet ... error

更新ipykernel或其他任何内容都会导致linkerror和回滚
