您必须对此文件进行更改 {project_root}\node_modules\metro-config\src\defaults\blacklist.js
有一个无效的正则表达式需要更改。我更改了以下的第一个表达式sharedBlacklist:
var sharedBlacklist = [
/node_modules[/\\]react[/\\]dist[/\\].*/,
/website\/node_modules\/.*/,
/heapCapture\/bundle\.js/,
/.*\/__tests__\/.*/
];

至
var sharedBlacklist = [
/node_modules[\/\\]react[\/\\]dist[\/\\].*/,
/website\/node_modules\/.*/,
/heapCapture\/bundle\.js/,
/.*\/__tests__\/.*/
];

希望对您有帮助...
您似乎遇到了此错误: https: //github.com/facebook/react-native/issues/26598。根据问题单,您有一些替代方案:
第一个选项:降级到节点 10.16.3 LTS
第二个选项:如果您使用 Yarn,请在 package.json 中添加“resolutions”属性以指向修复了问题的 Metro-config 版本:
"resolutions": {
"metro-config": "0.57.0"
},

第三种选择:如果您使用 npm 而不是yarn,则需要找到一种方法将“metro-config”子依赖项修复为“0.57.0”。我不知道该怎么做,也许 npm-shrinkwrap 可以帮助你。
