用内置命令重启内核后会直接失败并且出现授权问题，直接在命令行输入wolframscript会出现免费的liscense只能两个设备使用的问题，从而激活不了

The Wolfram Engine could not be activated using your Wolfram ID.

This may have occurred because WolframScript has already activated a different installation of the Wolfram Engine using your account's limited free activation keys. Only two keys are generated when you create a free Wolfram Engine license using https://www.wolfram.com/engine/free-license/.

For additional Wolfram Engine keys, contact Wolfram Research at https://www.wolfram.com/contact-us/.

好像只要关闭vscode再开启vscode就会出现这个问题，感觉是因为vscode退出后连接没有中断导致的

[xiajunwen1007]

在终端中发现确实多出了好几个kernel，如果把这些kernel全关掉就正常了

[xiajunwen1007]

是不是添加一条命令先检查是否存在kernel，如果存在就不添加新的kernel。重启kernel的命令感觉像是直接新建一个kernel而不是先关闭再添加一个。关闭kernel的这个命令是可以使用的，先使用关闭kernel再启动一个kernel这两个操作和在一起是没问题的。可能可以这样更改一下

你可以试一下安装这个版本，看看内核重启的问题有没有解决

解决了，感谢
