更新到 Spyder 4.0.0 时出错
问题我在 Windows 10、64 位下。
我曾尝试使用 Anaconda prompt 和 Anaconda Navigator 多次更新 Spyder 4.0.0。
它失败。我卸载了 Anaconda 并重新安装了它。
然后我以管理员身份运行 Anaconda 提示符并执行：
康达更新间谍
Spyder 的版本是 3.3.6。
我试过这个命令：
conda install spyder=4.0.0
提示返回：
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

启动 Anaconda Navigator 时，Spyder 版本仍然是 3.3.6 版本。
为了使以前版本的 Spyder 受益，我缺少什么？
编辑1：
当我尝试使用 anaconda navigator 时，它说：
它建议安装其他环境，但我希望 Spyder 被更新而不是安装在其他地方。
编辑2：
我成功将 conda 更改为 4.6，但出现以下两个错误：
FileNotFoundError: 没有这样的文件或目录：'C:\\Users\\brichard\\AppData\\Local\\Continuum\\anaconda3\\Menu\\spyder_shortcut.jsodone
也：
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，因为执行后会引发相同的错误。

（这里是 Spyder 维护者）其他用户反映需要运行
康达更新蟒蛇
然后
conda 安装 spyder=4
成功更新到版本 4。
