原因

Windows系统默认禁止运行脚本，导致无法执行Vue CLI的命令。解决这个问题的方法是更改执行策略。

解决办法

以管理员身份打开PowerShell：在开始菜单中找到PowerShell，在其上单击右键，并选择“以管理员身份运行”。

1.输入以下命令以更改执行策略为RemoteSigned：
Set-ExecutionPolicy RemoteSigned
2.在出现的提示中，输入"Y"来确认更改。
现在，应该能够在PowerShell中正常运行Vue CLI的命令了。可以再次尝试运行vue -v来检查Vue CLI的版本。

3.如果您想要在其他方式下运行脚本，也可以使用以下命令来更改执行策略：
Set-ExecutionPolicy Unrestricted

请注意，更改执行策略可能会增加系统的安全风险。建议在执行脚本时采取谨慎措施，只运行来自可信来源的脚本。
