重新安装android studio后出现的问题

由于未知原因，android studio无法启动

参考上述页面重新安装，并选择“卸载以前的版本”

在那之后，我开始了android studio的新版本

如果按照上一页所述运行测试

我得到了上面的错误

颤振医生的结果如下

这是否需要安装颤振和飞镖

然而，在这一点上，其他代码（默认计数器应用程序等）可以正常执行，所以我认为颤振和飞镖已经安装

然而，我认为颤振医生的结果是“安装颤振和飞镖”

Mac重启， 跑得干干净净 运行颤振升级 我在上面试过，但没有改变

我该怎么办。 按Ctrl-Alt-S（设置）

然后选择插件

然后搜索颤振

然后安装它

然后会提示安装dart

那你就可以走了

如果这不起作用 然后在您的机器上安装颤振，并使用android studio进行设置 试试这个youtube视频

happy coding

此时，其他Dart代码（如默认计数器应用程序）可以正常运行，因此我认为已经安装了Flatter和Dart。所以我不能安装颤振和飞镖。事实上，当我打开设置屏幕时，颤振和省道已经被检查过，无法安装。然而，这并没有反映在《颤振博士》的结果中。我处于这种情况，我需要采取任何行动吗？你试过了吗？是的，我试过了。但我不能安装它。我想它已经安装好了。否则，颤振应用程序将无法运行。但是颤振医生说，“安装颤振和飞镖。”
