Error [ERR_REQUIRE_ESM] for module to-valid-identifier since v61.1.3/v61.1.4 #1583
Description
Since adding package to-valid-identifier as a dependency in v61.1.3 and v61.1.4 (4349209), our CJS project could not run eslint anymore with the error ERR_REQUIRE_ESM.
Can be reproduced by creating a new CJS project, installing eslint and eslint-plugin-jsdoc then copying the config below.
Expected behavior
ESLint should run with CommonJS projects.
Actual behavior
ESLint throws error:
Error [ERR_REQUIRE_ESM]: require() of ES Module C:\Users\MA20507358\Downloads\eslint-issue\node_modules\to-valid-identifier\index.js from C:\Users\MA20507358\Downloads\eslint-issue\node_modules\eslint-plugin-jsdoc\dist\rules\preferImportTag.cjs not supported. Instead change the require of index.js in C:\Users\MA20507358\Downloads\eslint-issue\node_modules\eslint-plugin-jsdoc\dist\rules\preferImportTag.cjs to a dynamic import() which is available in all CommonJS modules. at TracingChannel.traceSync (node:diagnostics_channel:315:14) at Object.<anonymous> (C:\Users\MA20507358\Downloads\eslint-issue\node_modules\eslint-plugin-jsdoc\dist\rules\preferImportTag.cjs:10:49) ESLint Config
