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：

  3. 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: [Errno 2] 没有这样的文件或目录：'C:\\Users\\brichard\\AppData\\Local\\Continuum\\anaconda3\\Menu\\spyder_shortcut.jsodone

也：
  1. CondaError: Cannot link a source that does not exist. C:\Users\brichard\AppData\Local\Continuum\anaconda3\Scripts\conda.exe
  2. Running `conda clean --packages` may resolve your problem.
复制代码

conda clean --packages 命令没有帮助，因为执行后会引发相同的错误。

回答
（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。
