Cannot find module 'cheerio' from 'node_modules/enzyme/build/Utils.js'

[mmarshad]

I just start receiving this message to my unit tests today, although it was working fine before

Cannot find module 'cheerio' from 'node_modules/enzyme/build/Utils.js'

Require stack:
  node_modules/enzyme/build/Utils.js
  node_modules/enzyme/build/ShallowWrapper.js
  node_modules/enzyme-to-json/utils.js
  node_modules/enzyme-to-json/createSerializer.js

  at Resolver.resolveModule (node_modules/jest-runtime/node_modules/jest-resolve/build/index.js:306:11)
  at Object.<anonymous> (node_modules/enzyme/src/Utils.js:9:1)

Is there anything changed in serlizer.js?
"enzyme": "^3.11.0",
"enzyme-adapter-react-16": "^1.15.6",
"enzyme-to-json": "^3.6.1",

enzyme-to-json is not maintained by the enzyme team, so you'd have to ask them.

Same here for me:

`

My dependencies:
"enzyme": "^3.11.0",
"enzyme-adapter-react-16": "^1.15.5"

Please try pinning cheerio to =1.0.0.rc-3, ensure it's installed, and let me know if the issue persists.

Adding an override doesn't fix the issue with enzyme incorrectly using a loose RC pattern for a hard dependency.

  "overrides": {
    "enzyme": {
      "cheerio": "1.0.0.rc-3"
    }
  },

Cheerio is now a dual CommonJS and ESM module. That means that deep imports will now fail in newer versions of Node.
https://github.com/cheeriojs/cheerio/releases/tag/v1.0.0-rc.11

[ljharb]

@rxgx while that should work - file an issue with npm if it doesn't - simply adding "cheerio": "=1.0.0.rc-3" to your devDependencies should be sufficient, no overrides required.

[rxgx]

@ljharb what old version of npm are you using?

npm ERR! code EINVALIDTAGNAME
npm ERR! Invalid tag name "=1.0.0.rc-3" of package "cheerio@=1.0.0.rc-3": Tags may not have any characters that encodeURIComponent encodes.

[ljharb]

works fine with every version of npm, through the latest. That's a version specifier, not a tag name.

It's what the next release of enzyme will use: https://github.com/enzymejs/enzyme/blob/master/packages/enzyme/package.json#L42

[rxgx]

Is it possible that this version is missing from the registry? I get these errors even with rm node_modules and npm cache verify. OR something up with npm itself

[ljharb]

Is it possible you're not using the public registry? It's quite there: https://unpkg.com/browse/cheerio@1.0.0-rc.3/

[rxgx]

Here's what I originally thought was the resolution before being derailed by the invalid = syntax. I got the hyphen and dots mixed up.

  "overrides": {
    "enzyme": {
      "cheerio": "1.0.0-rc.3"
    }
  },

If you manually change the version of the dependencies or devDependencies, your lock file is unfortunately going to be out of sync.

[ljharb]

The = syntax is a range; overrides takes a specific version - it’s not invalid in general, i just wasn’t providing an override. Overrides should be used only as a last resort.

[nspector]

Looks like the change to pin it here: cafdb2b
was never published: https://unpkg.com/browse/enzyme@3.11.0/package.json. Can somebody publish it? Thank you!

[ljharb]

@nspector correct; it hasn't been published yet. it'll be in the next release.

Again, you can get the benefit now merely by doing npm install --save-dev cheerio@=1.0.0-rc.3.

[tonnyskk]

Try lock your cheerio version to 1.0.0-rc.10 E.g. by yarn resolutions. 1.0.0-rc.11 will throw the error.

[billnbell]

This worked for me

   "resolutions": {
+    "cheerio": "1.0.0-rc.10"
   },
