Question

我正在尝试将本机反应更新为最新版本。我运行命令：react-native upgrade --verbose

但是，它正在返回：

info No version passed. Fetching latest...
info Fetching diff between v0.59.8 and v0.60.5...
error Cannot read property 'toLowerCase' of undefined
debug TypeError: Cannot read property 'toLowerCase' of undefined
    at getPatch (/Users/myUser/Documents/React Native/myApp/node_modules/@react-native-community/cli/build/commands/upgrade/upgrade.js:109:121)
    at process._tickCallback (internal/process/next_tick.js:68:7)

如何升级本机反应？

Answer 1

在package.json文件中添加name属性。这样可以解决问题

react-native升级返回未定义的“ toLowerCase”
