Public bug reported:
node-cheerio 1.2.0+~cs2.1.0-2 in stonking-proposed cannot be loaded with
require(), which breaks CommonJS consumers. This blocks node-cheerio
from migrating and, through it, node-parse5 and node-jsdom.
Symptom: the eslint autopkgtest fails on every architecture (amd64, amd64v3,
arm64, armhf, ppc64el) when triggered by node-cheerio/1.2.0+~cs2.1.0-2:
not ok 381 - tests/lib/cli-engine/formatters/html.js
message: '"cheerio" is not found.' ruleId: node/no-missing-require
https://autopkgtest.ubuntu.com/results/autopkgtest-stonking/stonking/amd64/e/eslint/20260928_111538_1192f@/log.gz
Reproducer (Node 24.19, stonking-proposed):
$ node -e 'require("cheerio")'
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in
/usr/share/nodejs/cheerio/package.json
Cause: upstream cheerio 1.2.0 is a dual CJS and ESM package built with tshy,
and its exports include
"require": { "types": "./dist/commonjs/index.d.ts", "default":
"./dist/commonjs/index.js" }
debian/patches/debian-build-adjustments.patch removes the "require" conditions
for ".", "./slim" and "./utils" and sets the tshy "dialects" to ["esm"]. The
binary package therefore ships only dist/esm and dist/browser, with no
dist/commonjs. None of the other changes in that patch (TypeScript 5.2
compatibility, the cheerio-select adapter fix, dropping
fromURL/loadBuffer/stream helpers) appear to need ESM-only output.
Impact on proposed-migration: node-parse5 8.0.1+dfsg-3build3 Breaks
node-cheerio (<< 1.2~) and node-jsdom (<< 20.0.3+~cs124.18.21-7~).
Because node-cheerio is not a candidate, node-parse5 makes jest, ts-
jest, node-jest-react, jupyterlab, node-jupyter-widgets-*, node-bqplot,
node-ipydatagrid, node-jsdom, node-cheerio, node-http-server,
perlnavigator and python-ipywidgets-doc uninstallable, so it stays in
proposed. node-jsdom -10build3 is in turn held behind node-parse5.
Suggested fix: keep the CommonJS dialect ("dialects": ["esm",
"commonjs"]) and the "require" export conditions in debian-build-
adjustments.patch, so that dist/commonjs is built and shipped again.
This should also be fixed in Debian, where no bug has been reported yet.
