Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './lib/sync' is not defined by "exports" in node_modules\csv-parse\package.json

Question

Whenever I run index.js in nodejs I get this error message.

This error only comes up when I try to add this line of code

const PrettyTable = require('prettytable');

I'm creating a bot, and I would like to send a message in tabular form but when I try to add require('pretty table') if gives me the error above.

Things I've tried: Installed prettytable with npm, Deleted node_modules and reinstalled every package, Run npm update But nothing has worked.

Here is the node_modules\csv-parse\package.json file for reference

I'm new to this so I would really appreciate all the help I can get, thank you.

Answer 1

I fixed the problem by modifying exports in node_modules\csv-parse\package.json. I switched it from "./sync" to "./lib/sync" as one of the comments stated. Thanks for the help.
