更新后 Spyder 无法在 Anaconda 中启动 (4.1.2) [英] Spyder failed to launch in Anaconda after update (4.1.2)

问题描述

我刚刚将 Spyder 更新到 4.1.2，当我尝试启动它时，它现在会产生错误并且无法启动.

I have just updated Spyder to 4.1.2 and when I try to launch it, it now produces an error and fails to launch.

conda list pylint我该如何解决这个问题?

Output from conda list pylint How can I solve this?

错误:

推荐答案

这似乎是默认频道提供的pylint包中的错误.包定义中当前缺少依赖项 toml.

This seems to be an error in the pylint package provided by the default channels. The dependency toml is currently missing in the package definition.

目前的快速解决方法是降级到以前的版本:

A quick workaround for now is to downgrade to the previous version:

conda install "pylint<2.5"
