workers: InvalidStateError: Failed to register a ServiceWorker: The document is in an invalid state..
As an AI language model, I do not have access to your specific code or context, so I can only provide general information about this error.
The "InvalidStateError" message typically indicates that the browser is trying to register a service worker in a state where it is not allowed. For example, service workers can only be registered on secure origins (HTTPS or localhost), and may not work correctly in certain browser contexts such as incognito mode.
To troubleshoot this error, you can try the following steps:
1. Check that your website is being served over HTTPS or on localhost. If not, you'll need to secure your site to use service workers.
2. Make sure that your code for registering the service worker is being called in the correct context. For example, the registration code should not be called before the page has finished loading.
3. Check the browser console for any other error messages that may be related to the invalid state error.
4. If you are still having issues, try testing your code in a different browser or context to see if the issue is specific to your environment.
If none of these steps resolve the issue, you may need to seek additional help in troubleshooting the specific code and context of your application.
WARNING: The scripts dask-scheduler, dask-ssh and dask-worker are installed in '/home/jinhy/.local/bin' which is not on PATH.警告怎么解决
这个警告提示你的 Dask 相关脚本被安装在了 `/home/jinhy/.local/bin` 目录下,但是该目录没有被添加到系统环境变量 PATH 中,导致无法直接使用这些脚本。
解决方法是将该目录添加到 PATH 环境变量中。可以在终端中运行以下命令:
```
export PATH="$PATH:/home/jinhy/.local/bin"
```
如果希望每次登录时都自动添加该目录到 PATH 中,可以将上述命令添加到 `~/.bashrc` 或 `~/.bash_profile` 文件中。
