Trouble updating to Spyder 4.0.0
问题 I am under Windows 10, 64 bits. I tried several time to update Spyder 4.0.0 with both the Anaconda Prompt and the Anaconda Navigator. It failed. I uninstalled Anaconda and reinstalled it. Then I ran the Anaconda Prompt as an Administrator and executed : conda update spyder The version of Spyder was 3.3.6. I tried this command : conda install spyder=4.0.0 The prompt returned : Collecting package metadata (current_repodata.json): done Solving environment: failed with initial frozen solve.
