In a create-react-app
项目,我正在使用@babel/plugin-proposal-optional-chaining
在我的`.babelrc中
但是,我有这个错误:Module parse failed: Unexpected token (22:16) You may need an appropriate loader to handle this file type.
这是我所有的 babel 依赖项:
{

"@babel/core": "^7.9.0",
"@babel/node": "^7.8.7",
"@babel/plugin-external-helpers": "^7.8.3",

}
}
- 节点 v14.0.0
- npm 6.14.4

为了让它发挥作用,我还需要什么?
