Anaconda Spyder 5元'；t发射

我刚刚下载了Spyder 5

conda upgrade anaconda
conda install spyder=5.0.0

但是，安装后，当我从Windows菜单启动Spyder时，我会看到一个弹出窗口，指示Spyder 5正在启动。但是，几秒钟后，弹出窗口消失，Spyder不会启动

当我尝试从Anaconda Navigator启动Spyder时，出现以下错误：

我已经尝试过以下方法（未成功）：

• 卸载（通过Windows菜单）Spyder并在Anaconda提示符下重新安装
• 再次安装Spyder 4

  conda安装Spyder=4.0.0

  。然而，这也不再启动

如何再次启动Spyder？

我遇到了同样的问题，我刚刚用Uninstall-anaconda.exe完全卸载了anaconda 3，然后重新安装并更新了所有内容。这对你来说可能不是一个可行的选择，但我确实让它工作了。

下面的命令对我有效，但没有破坏任何东西：

conda update anaconda

然后

conda install spyder=5

（此处为Spyder maintainer）这部分错误

ImportError:无法从“jupyter\u core.path”导入名称“secure\u write”

表明您在Anaconda中存在严重的安装问题。所以我的建议是卸载并重新安装Anaconda。要做到这一点，请按照中的说明进行操作。如果您想使用Spyder而不出现任何问题，并避免每次更新Anaconda后所涉及的所有头痛问题，另一个选择是使用我们的。@CarlosCordoba建议现在安装它？应该说，在升级弹出窗口中（而不是

conda install spyder=5.0.0

，它破坏了一切）？现在建议使用Windows和macOS安装程序安装spyder。我们在和中提到了这一点。但是，如果您将Spyder与Anaconda一起安装，那么我们必须告诉人们如何使用

conda

更新它（我认为推荐一种不同的方法会让人很困惑）。不幸的是，我们无法控制

conda

如何执行更新，这就是我们创建安装程序的原因。通常，使用不同的环境（而不是基本环境）来尝试新版本是一个不错的策略，在安装新的主要版本（不仅是Spyder，还包括所有软件）之前，请等待几个月。
