有人可以帮忙解决这个问题吗?

(这里是 Spyder 维护者) 在这种情况下，我们更新 Spyder 的常规指令不起作用，因为 Spyder 之间存在一些不兼容的依赖关系5.0.5 和 5.1.5.

要解决此问题，您需要关闭 Spyder 并在 Anaconda Prompt(或 Linux 或 macOS 上的系统终端)中运行以下命令:

conda 删除 spyderconda 删除 python 语言服务器康达更新蟒蛇康达安装间谍=5.1.5

第二个或第三个命令(即 conda remove python-language-server 或 conda update anaconda)可能会给您错误，但没关系.只需忽略它们并继续执行其他命令即可.

I installed anaconda and spyder came with the installation. Spyder 4.2.5 came with the installation and I got a pop up notification that spyder=5.1.5 is available. I tried

conda update anaconda

conda install spyder=5.1.5

and gets an error:

Solving environment: failed with initial frozen solve. Retrying with flexible solve.

I tried letting it run for more than 8 hours, but I had to cancel it because I got tired.

Tried

conda install anaconda spyder=5.1.5

and gets another error:

`Solving environment: failed with initial frozen solve. Retrying with flexible solve. Collecting package metadata (repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve.

PackagesNotFoundError: The following packages are not available from current channels:

Current channels:

To search for alternate channels that may provide the conda package you're looking for, navigate to

and use the search bar at the top of the page.

Can someone please help on how to solve this?

(Spyder maintainer here) Our regular instructions to update Spyder don't work in this case because there are some incompatible dependencies between Spyder 5.0.5 and 5.1.5.

To workaround this problem, you need to close Spyder and run the following commands in the Anaconda Prompt (or your system terminal on Linux or macOS):

conda remove spyder
conda remove python-language-server
conda update anaconda
conda install spyder=5.1.5

The second or third commands (i.e. conda remove python-language-server or conda update anaconda) could give you errors, but that's fine. Simply ignore them and continue with the other commands.
