Ionic CLI TypeError

Hi there,

I recently installed @ionic/cli via NPM, with the LTS branch of Node on macOS Catalina.

However, running any ionic command results in a TypeError from index.js:

exports.pathExists = pathExists;

TypeError: Cannot set property pathExists of #<Object> which has only a getter

I’ve tried uninstalling/reinstalling Node, upgrading to latest; uninstalling @ionic/cli, even attempted installing the old deprecated “ionic” package, all with the same issue. I can’t even run ionic --version without this issue appearing.

Any help would be greatly appreciated.

Posted the same issue just 5 minutes back. Getting this issue after updating.

I saw your post almost immediately after posting mine; couldn’t reply for some reason.

It’s at least comforting to know that I’m not alone with this issue. Please let me know if you find a solution.


I’m having the same issue, I tried to reinstall everything but still having this issue

Having exactly the same issue

As all the users above, I’m having the same exact issue using the deprecated package, not tried the new one

A Github issue opened for this about an hour ago as well. Leaving it here for anyone else who may want to track/follow the issue.


Thank you so much for this. Trying to work out a bug for a client all day and its become so frustrating when a blank template doesn’t event work!

npm i -g @ionic/cli@6.9.1


Looks like it just got fixed in a new version (6.9.1).

Hey, sorry to interrupt but did the fix work for you? Running ionic serve after a clean project using ionic1 still shows the same error for me.

I fixed my update not reflected issue by running npm i -g @ionic/v1-toolkit@3.2.2 on the project root :+1:

I have a similar problem when running “ionic serve” and this is the message:
“TypeError: Cannot set property pathExists of # which has only a getter%”

├── @ionic/cli@6.9.1
├── npm@6.14.4
└── sass@1.23.1

I think that you have to remove global option (-g) to update local version. For me it worked, thanks!!

I solved it by running these commands:

npm uninstall -g @ionic/cli 
npm cache clear --force
npm install -g @ionic/cli@6.9.1

Hope it will help you.

Well, I seem to be stuck still. Brand new MacBook so I just installed ionic this morning. Uninstalling and cache cleaning doesn’t seem to work at all. After doing those I run ionic --version and I get the same pathExists error so it seems one or both of those commands isn’t working.

UPDATE: I had to totally remove node and reinstall it, then install ionic 6.9.1 and the pathExists error is gone now.
