yarn --version returns 1.15.2 但在 package.json 中是 1.19.1

Question

我刚刚在 React Native 0.61.2 应用程序上重新安装 yarn 到最新的 1.19.1。

 npm install yarn

然后使用 yarn install、

重新安装模块

 yarn install

然后 yarn --version 仍然是 returns 1.15.2，而在 package.json 中是 1.19.1。这是 package.json:

    "@react-native-community/async-storage": "^1.6.2",
    "moment": "^2.24.0",
    "react": "16.11.0",

Answer 1

如果你有全局的纱线包，这可能是 return 全球纱线版本。如果你想确定项目的 yarn 版本，你需要检查项目的 "node_modules" 文件。最后但同样重要的是，在安装新的次要版本的软件包之前，您应该删除 "package-lock.json" 和 "yarn.lock" 文件。
