无法从visual studio代码运行新创建的react本机项目

sdk visual-studio-code react-native android

Alen.Toma · 技术社区 · 3 年前

我是新来的本地反应,我总是与视觉工作室2019合作。我曾在Xamarin工作过。如您所知,当您下载Visual studio并使用xamarin时,android SDK安装在

C:\Program Files (x86)\Android\android-sdk\platform-tools

adb位于哪个位置 C:\Program Files (x86)\Android\android-sdk\platform-tools

所以我创造了一个 local.properties 并添加 sdk.dir=C:\Program Files (x86)\Android\android-sdk\platform-tools

然后我在android上运行我的react原生项目。

此外,除了下面我得到的错误之外 java.io.IOException: The filename, directory name, or volume label syntax is incorrect 我也没有找到模拟器,这很奇怪,因为我在上面的路径中安装了所有模拟器。所以我插上了我的安卓设备。

如果这与visual studio 2019开始安装的android SDK有关,请指导我

如果你是windows用户,

您已使用android studio或CMD手动打开模拟器。

为什么?

react native run android命令在windows中不会自动启动模拟器。
