【问题描述】：

我刚刚下载了 Spyder 5 使用

conda upgrade anaconda
conda install spyder=5.0.0

但是，安装后，当我从 Windows 菜单启动 Spyder 时，我看到一个弹出窗口，表明 Spyder 5 正在启动。但是，几秒钟后弹出窗口消失，Spyder 没有启动。

当我尝试从 Anaconda Navigator 启动 Spyder 时，我收到以下错误：

我已经尝试过以下事情（不成功）：

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 install spyder=4.0.0。但是，这也不再启动。

我该怎么做才能再次启动 Spyder？

【问题讨论】：

(这里是 Spyder 维护者) 你的这部分错误ImportError: cannot import name 'secure_write' from 'jupyter_core.paths' 表明你在 Anaconda 中安装有严重的问题。所以我的建议是再次卸载并重新安装 Anaconda。为此，请按照our video 中的说明进行操作。

如果您想毫无问题地使用 Spyder 并避免在 Anaconda 每次更新后所涉及的所有麻烦，另一种选择是使用我们的Windows installer。

@CarlosCordoba 这是现在推荐的安装方式吗？应该说在升级弹出窗口中（而不是 conda install spyder=5.0.0 破坏一切）？

现在推荐使用我们的 Windows 和 macOS 安装程序来安装 Spyder。我们在docs、webpage 和Github releases page 中提到了这一点。

但是，如果你用 Anaconda 安装了 Spyder，那么我们必须告诉人们如何使用 conda 来更新它（我认为推荐不同的方法会很混乱）。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您的基础环境来尝试新版本是一个很好的策略，并等待几个月再安装新的主要版本（不仅是 Spyder，而且是任何一般软件）。

【参考方案1】：

您需要删除 Spyder 历史记录。

rm ~/.config/spyder-py3

【参考方案2】：

我遇到了同样的问题，我刚刚使用 Uninstall-Anaconda.exe 完全卸载了 anaconda 3，然后我重新安装并再次更新了所有内容。这对你来说可能不是一个真正可行的选择，但我确实让它起作用了。

【参考方案3】：

以下命令对我有用而不会破坏任何东西：

conda update anaconda

然后

conda install spyder=5
