【问题描述】：

我正在使用 Expo CLI。我想在 React Native 中使用 SVG。所以，我按照https://github.com/react-native-svg/react-native-svg 的说明进行操作。但是当我安装expo install react-native-svg 时收到以下错误：

expo install react-native-svg 
    > yarn add react-native-svg
    yarn add v1.22.11

    error Running this command will add the dependency to the workspace root rather than the workspace itself, which might not be what you want - if you really meant it, make it explicit by running this command again with the -W flag (or --ignore-workspace-root-check).

当我尝试这个命令yarn add react-native-svg时，我收到了这个错误

yarn add react-native-svg
error Running this command will add the dependency to the workspace root rather than the workspace itself, which might not be what you want - if you really meant it, make it explicit by running this command again with the -W flag (or --ignore-workspace-root-check).

有什么建议吗？我是 Expo 和 React Native 的新手。

【解决方案1】：

根据这个话题why does yarn warn when adding a dependency to the root workspaces package.json，现在我可以用下面的命令安装了。

yarn workspace mobile-app add react-native-svg

【解决方案2】：

也许你应该使用 expo 命令

expo install react-native-svg

【讨论】：

其实我之前输入过"expo install react-native-svg"这一行。之后，“yarn add react-native-svg”这一行会自动出现在下面，然后是上面的错误代码，如您在屏幕截图链接中所见。我已经编辑了帖子，请查看截图链接。
