node.js - 安装包后 npm start 中断
问题描述
下面的原始问题
如果您现在使用,该错误似乎已修复create-react-native-app
。它现在使用 react 0.55.2。
我们有一个正在使用 react native 构建的项目。
当我从网站运行这些命令时:
create-react-native-app AwesomeProject
我运行npm start
它完美无缺。
如果我更改我的包(我添加了这一行):
"react-native-form-builder": "^1.0.15",
我跑npm install
了,跑完之后npm start
,我得到了这个错误:
C:\everforms>npm start
> everforms@0.1.0 start C:\everforms
> react-native-scripts start
11:57:29: Starting packager...

为什么会这样?
解决方案
此错误是 react-native 0.56 中影响 Windows 用户的新错误。要解决它,您可以使用另一个 react-native 版本创建一个项目:
react-native init --version="0.55.4" MyNewApp
