我在 Windows 10 下，64 位。
我多次尝试使用 Anaconda Prompt 和 Anaconda Navigator 更新 Spyder 4.0.0。
它失败了。我卸载了 Anaconda 并重新安装了它。
然后我以管理员身份运行 Anaconda Prompt 并执行:
conda update spyder
Spyder 的版本是 3.3.6。
我试过这个命令:
conda install spyder=4.0.0

启动 Anaconda Navigator 时，Spyder 版本仍为 3.3.6。
为了使 Spyder 的最新版本受益，我缺少什么？
编辑 1:
当我尝试使用 Anaconda Navigator 时，它说:
spyder 4.0.0 cannot be installed on this environment
它建议安装其他环境，但我希望更新 Spyder，而不是安装在其他地方。
编辑 2:
我成功地将 conda 更改为 4.6，但出现以下两个错误:
FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\brichard\\AppData\\Local\\Continuum\\anaconda3\\Menu\\spyder_shortcut.jsodone
和 :
CondaError: Cannot link a source that does not exist. C:\Users\brichard\AppData\Local\Continuum\anaconda3\Scripts\conda.exe
Running `conda clean --packages` may resolve your problem.
conda clean --packages命令没有帮助，因为在执行后会引发相同的错误。
最佳答案
(Spyder 维护者在这里)其他用户报告说你需要运行conda update anaconda
进而conda install spyder=4
成功更新到版本 4。
希望有帮助。
