title: Spyder 5 missing dependencies - spyder_kernels version error

  <p>Spyder gives me error message like above, but I cannot solve it.</p>
  <p>I think the version of spyder_kernels should be 2.0.1 at least, but I already updated my version as 2.0.1.</p>
  <p>Why I get such warning message? &amp; How can I solve it?</p>
  <p>I reinstalled spyder-kernels both conda and pip, but it didn't help.</p>
