小编ka.*_*ean的帖子

我正在尝试构建一个正则表达式来判断字符串是否是有效的文件扩展名.它可能是任何扩展.

hello        no
.hello       Yes
..hello      No
hello.world  No
.hello.world No
.hello world No

我试过^ \.和^ \.[\.]但是无法得到我想要的东西.这似乎应该很简单.

我们得到跟踪：节点类型RestProperty在我们的构建中已重命名为RestElement warnings。构建成功，但是自升级到babel 7.0.0以来，还有很多这样的构建

我在这里尝试了该解决方案的跟踪：节点类型SpreadProperty在Object.isSpreadProperty处已重命名为SpreadElement，但似乎无法解决此问题

relevent package.json：

"devDependencies": {
    "@babel/core": "^7.0.0",
    "@babel/plugin-proposal-class-properties": "^7.0.0",
    "@babel/plugin-proposal-export-default-from": "^7.0.0",
    "@babel/plugin-syntax-dynamic-import": "^7.0.0",
    "@babel/plugin-transform-modules-commonjs": "^7.0.0",
    "@babel/plugin-transform-regenerator": "^7.0.0",
    "@babel/polyfill": "7.0.0",
    "@babel/preset-env": "^7.0.0",
    "@babel/preset-react": "^7.0.0",
...
    "babel-core": "^7.0.0-bridge.0",
    "babel-eslint": "^10.0.0",

babelrc：

{
  "presets": ["@babel/preset-env", "@babel/preset-react"],
  "plugins": [
    "@babel/plugin-proposal-export-default-from",
    "@babel/plugin-syntax-dynamic-import",
    ["@babel/plugin-proposal-class-properties", { "loose": false }],
  ],
  "env": {
    "test": {
      "plugins": ["transform-es2015-modules-commonjs", "transform-regenerator"]
    }
  }
}
