尝试更新 conda 软件包后，我无法再启动 Jupyter Notebook 或 Jupyter Lab。大多数 conda 命令也会导致终端出现错误。虽然每个命令都会导致略有不同的错误，但每个命令都以以下语句终止：

ImportError: dlopen(/Users/USERNAME/anaconda3/lib/python3.7/lib-dynload/_ctypes.cpython-37m-darwin.so, 2): Library not loaded: @rpath/libffi.6.dylib
  Referenced from: /Users/USERNAME/anaconda3/lib/python3.7/lib-dynload/_ctypes.cpython-37m-darwin.so
  Reason: image not found

例如，尝试运行 jupyter lab 会导致：
