commonjs - Missing export (Error: ... is not exported by ...)

[danielgindi]

• Rollup Plugin Name: commonjs
• Rollup Plugin Version: 20.0.0
• Rollup Version: 2.56.3
• Operating System (or Browser): macOS
• Node Version: 16
• Link to reproduction (⚠️ read below): https://replit.com/@danielcgindi/rollup-plugin-repro-4

Expected Behavior

Should correctly export whatever is imported.

Actual Behavior

Weird and irrelevant export.

The piece of code (importDeclaration.module.info.code) that fails looks like this:

import * as commonjsHelpers from "commonjsHelpers.js";
import { __exports as mongodb } from "\u0000/Users/user/git/server/node_modules/mongodb/index.js?commonjs-exports"

export default commonjsHelpers.commonjsRequire("/$$rollup_base$$/node_modules/mongodb/index.js", "/$$rollup_base$$/node_modules/mongodb");

@lukastaegert this looks like it's originating from the latest refactor during the circular dependencies support. While mongodb cannot be rolled up normally as it has severe circular dependencies, it seems to not be able to be rolled up dynamically too due to this bug. It looks like this should have been a reexport of __exports or at least *. I tried to look into this and have not found what causes this to compose in such a way. It's probably line 228 in index.js, but how do we make it play well with the other stuff that's being shoved in there?

[lukastaegert]

Seems to be resolved by #1038

[phihu]

There still seems to be the or at least a bug.

In Short: I am importing a lib that depends on axios/axios.

After updating to a version > 18 the import failed with

The requested module ... does not provide an export named 'exports'

as mentioned here and in the related post here: #modernweb-dev/web#1700.

Following the discussion(s) in #1038 and updating to v20.0.4 (beta), I get the following (new) error, though:

Error while transforming ... Could not resolve import "commonjsHelpers.js"

1 | import * as commonjsHelpers from "commonjsHelpers.js";
2 | import require$$0 from...

[emensch]

I'm in the same boat as @phihu - any advice or direction here would be much appreciated :)

[phihu]

Anyone any success? Problem still exists, even using the latest (beta) release v22.0.0-13

[mihaisavezi]

v22.0.0 release and problem still exists

try transforming to commonjs the deepmerge npm module

[b-houghton]

I also am getting the same kind of error message with version 22.0.0 when trying to process @testing-library/dom:

Error while transforming node_modules/@testing-library/dom/dist/helpers.js: Could not resolve import "commonjsHelpers.js".

For anyone stuck at this problem: downgrading @rollup/plugin-commonjs to v21 solves for me.

[jimblue]

I'm having the same issue using vitejs when importing photoswipe.

[Ssis53]

For anyone stuck at this problem: downgrading @rollup/plugin-commonjs to v21 solves for me. It works for me. thx！

[mhogara]

If anyone finds any additional solutions, please update the thread! I'm also facing the same issue and downgrading hasn't helped either.

[enjikaka]

Also having issues with this. Using via web-test-runner. Downgrading to v21 just freezes web-test-runner, while latest release errors with Could not resolve import "commonjsHelpers.js".

[jcoglan]

I'm also having the same problem. v22 gives me the error about commonjsHelpers.js while v21 causes wtr to hang and eventually crash due to running out of memory. This is on a hello-world demo with a single test just to try to get wtr working.

[trixter13]

Same issue here with web-dev-server. v22 has the mentioned error and v21.1.0 just hangs:

Same issue here with vitejs : I tried with @rollup/plugin-commonjs@20, @rollup/plugin-commonjs@21, @rollup/plugin-commonjs@latest (23) with the same result..

[pdmshrestha]

Any updates on this issue? v24.0.0 and still has issue.

[vtron]

Same issue still with v24.0.1 Could not resolve import "commonjsHelpers.js"

Is this being addressed?

[vtron]

I just tried this setting out and confirmed that it is still happening.

I am not using Vite, but I am am using Web Dev Server https://modern-web.dev/docs/dev-server/overview/ with Storybook, so I am setting strict-requires on the plugin through that config.

The issue seems to be that I am using an ES Module @.***/client-api) which imports a commonjs library.

The imports are for "global/window.js", "core-js/ and "qs".

Everything works fine when I have commonjs plugin active and I don't import the library I am having issues with.

Did you try

build: { commonjsOptions: { strictRequires: true } }

in your Vite config?

I also have this issue using vite --version: vite/4.1.4 darwin-x64 node-v18.14.0 vite dev server works. When i try to build i get RollupError:

"getAugmentedNamespace" is not exported by "commonjsHelpers.js", imported by "/opt/app/node_modules/react-use/esm/index.js?commonjs-proxy".
file: /opt/app/node_modules/react-use/esm/index.js?commonjs-proxy:1:9
1: import { getAugmentedNamespace } from "commonjsHelpers.js"; import * as esm from "/opt/app/node_modules/react-use/esm/index.js"; export default /*@__PURE__*/getAugmentedNamespace(esm);

When i add react-use to commonjsOptions.ignore, the error jumps to the next lib:

"getAugmentedNamespace" is not exported by "commonjsHelpers.js", imported by "/opt/app/node_modules/react-popper/lib/esm/index.js?commonjs-proxy".
file: /opt/app/node_modules/react-popper/lib/esm/index.js?commonjs-proxy:1:9
1: import { getAugmentedNamespace } from "commonjsHelpers.js"; import * as esm from "/opt/app/node_modules/react-popper/lib/esm/index.js"; export default /*@__PURE__*/getAugmentedNamespace(esm);

What am i missing? Any hints on investigating this?

I am using Rollup to create an npm pacakge and I have the following versions:

"rollup": "^3.29.4",
"@rollup/plugin-commonjs": "^25.0.7",

I can see in the bundle file that the plugin adds the line import * as commonjsHelpers from 'commonjsHelpers.js';. However, when I install the package on another project I get the above errors. Inspecting what is actually in the npm package, I cannot find the file "commonjsHelpers.js". Could it be a misconfiguration of the plugin?

A simplified rollup.config.ts version:

// omitting imports to save space

const rollupConfiguration = [
    {
        input: ['./src/index.tsx'],
        external: [...Object.keys(pkg.peerDependencies || {}), /@babel\/runtime/],
        output: [
            {
                file: pkg.main,
                format: 'cjs',
                sourcemap: !production,
            },
            {
                file: pkg.module,
                format: 'es',
                exports: 'named',
                sourcemap: !production,
            },
        ],
        plugins: [
            nodeResolve(),
            commonjs({
                sourceMap: !production,             
            }),
            babel({
                exclude: 'node_modules/**',
                presets: ['@babel/preset-react', ['@babel/preset-env']],
                babelrc: false,
                babelHelpers: 'runtime',
                plugins: ['@babel/plugin-transform-runtime'],
            }),
            postcss({
                extract: true,
                modules: false,
                use: ['sass'],
            }),
            typescript({
                sourceMap: !production,
                inlineSources: !production,

            }),
            production && terser(),
        ],
    },
];

export default rollupConfiguration;

Trying out and adding some babel/rollup plugins:

pnpm dlx create-remix@latest --template remix-run/remix/templates/unstable-vite-express

I also got that kind of error:
