Node error _xdl(...).ProjectUtils.readConfigJsonAsync is not a function - node.js

Question

After installing expo-CLI Version 3.5.0 to my computer so that I'm able to use it and then running npm start Node throws this error:" _xdl(...).ProjectUtils.readConfigJsonAsync is not a function. " I cannot find the solution to this online, it appears to be a new issue. Is anyone else running into this or have a solution for successfully running the program?

Answer 1

I also got the same issue. You don't need to downgrade node, just need to change some hashes on your project. (worked on node version 13.2.0 and expo-cli version 3.9.0 for me, although I have noticed that it also worked on LTS node 12.13.1 )
You can change the file located at:
\node_modules\metro-config\src\defaults\blacklist.js
From :
var sharedBlacklist = [
/node_modules[/\\]react[/\\]dist[/\\].*/,
/website\/node_modules\/.*/,
/heapCapture\/bundle\.js/,
/.*\/__tests__\/.*/
];
To:
var sharedBlacklist = [
/node_modules[\/\\]react[\/\\]dist[\/\\].*/,
/website\/node_modules\/.*/,
/heapCapture\/bundle\.js/,
/.*\/__tests__\/.*/
];

I need a solution as well. i have been using 3.5.0 version but today i tried to update it by mistake and i couldnt find a way yet to make it run normally. im starting to think the problem is server side or something updated is not compatible with old 3.5.0 version.
_xdl(...).ProjectUtils.readConfigJsonAsync is not a function
Screenshot of the error im getting
Edit: i just found the solution. new version of the xdl causes the error.
Fix:
Open up a command prompt(if you are on a windows machine), no matter which directory you are at, type commands below
npm uni -g --no-save #expo/xdl
npm i -g --no-save #expo/xdl#56.8.0
if you don't specify what version you want to install, npm or yarn will immediately select 56.8.1 version and installs automaticly and causes the error.
you need to downgrade to 56.8.0 version by typing the commands that i gave above.
