Cheerio: Running enzyme-jest with latest cheerio: memoizeCapped is not a function

[Tetheta]

Here's the error I'm getting:

Test suite failed to run

    TypeError: memoizeCapped is not a function

Yet the _memoizeCapped function the _stringToPath is trying to include is indeed there. I use get all the time with the latest lodash so I don't think it's lodash causing the issue here. Any ideas? I've tried every configuration/etc thing I can think of that would be an issue.

Jest config in package.json:

    "jest": {
        "unmockedModulePathPatterns": [
            "react",
            "enzyme",
            "jest-enzyme"
        ],
        "moduleNameMapper": {
            "\\.(jpe?g|png|gif|eot|otf|webp|svg|ttf|woff2?|mp[34]|webm|wav|m4a|aac|oga)$": "<rootDir>/__mocks__/fileMock.js",
            "\\.(css|less|s[ac]ss|styl)$": "<rootDir>/__mocks__/styleMock.js",
            "app": "<rootDir>/src/app.js"
        },
        "moduleFileExtensions": [
            "js",
            "jsx"
        ],
        "moduleDirectories": [
            "src",
            "src/js",
            "node_modules"
        ],
        "setupTestFrameworkScriptFile": "./node_modules/jest-enzyme/lib/index.js"
    },

.babelrc:

{
    "presets": [
        [
            "env",
            {
                "modules": false,
                "targets": { "browsers": "ie >= 11, ff >= 46, > 1%" },
                "useBuiltIns": true,
                "debug": false
            }
        ],
        "react"
    ],
    "plugins": [
        "transform-class-properties",
        "transform-object-rest-spread"
        //'react-hot-loader/babel',
    ],
    "env": {
        "test": {
            "presets": [
                "env",
                // {
                //  "modules": false,
                //  "targets": { "browsers": "ie >= 11, ff >= 46, > 1%" },
                //  "useBuiltIns": true,
                //  "debug": false
                // }
                "react"
            ],
            "plugins": [
                "transform-class-properties",
                "transform-object-rest-spread",
                "transform-export-extensions"
            ],
            "only": ["./**/*.js", "node_modules/jest-runtime"]
        }
    }
}

Still an issue for me. Can't run any of cheerio without this fixed and it's preventing me from upgrading to React16 which is a bit frustrating. I'll cross post to lodash maybe.

@Tetheta I'm not sure whether this problem is caused by cheerio. I fixed the problem with adding the https://github.com/59naga/babel-plugin-add-module-exports module. Here my .babelrc

{
  "presets": ["env", "react", "flow"],
  "env": {
    "test": {
      "plugins": [ "add-module-exports"],
      "presets": ["env", "react"]
    }
  }
}

and jest configuration

{
  "unmockedModulePathPatterns": [
   "react",
   "enzyme",
   "jest-enzyme"
  ],
  "moduleNameMapper": {
   "\\.(jpe?g|png|gif|eot|otf|webp|svg|ttf|woff2?|mp[34]|webm|wav|m4a|aac|oga)$": "<rootDir>/__mocks__/fileMock.js",
   "\\.(css|less|s[ac]ss|styl)$": "<rootDir>/__mocks__/styleMock.js",
   "app": "<rootDir>/src/app.jsx"
  },
  "moduleFileExtensions": [
   "js",
   "jsx"
  ],
  "moduleDirectories": [
   "src",
   "node_modules"
  ]
 }

There are a babel packages which I used

 "babel-cli": "^6.26.0",
  "babel-core": "^6.26.0",
  "babel-jest": "^21.2.0",
  "babel-loader": "^7.1",
  "babel-plugin-add-module-exports": "^0.2.1",
  "babel-plugin-transform-class-properties": "^6.24.1",
  "babel-plugin-transform-decorators-legacy": "^1.3.4",
  "babel-plugin-transform-runtime": "^6.23.0",
  "babel-preset-env": "^1.6.0",
  "babel-preset-flow": "^6.23.0",
  "babel-preset-react": "^6.24.1",
  "babel-runtime": "^6.26.0",

Apologies for forgetting to comment, but thanks a bunch @captainkovalsky ! This was indeed my issue (or at least let me see the other issues I had finally). Got it working after a bit more tweaking. I'll close this issue now.
