Installation Problem: .yarn-metadata.json: Unexpected end of JSON input #660

reggi · 2016-10-11T17:32:27Z

Seems that yarn is creating a json file without contents and perhaps should be {}.

We hit this at Exponent after getting a prior installation error due to a bad hash in the yarn.lock file. Current hypothesis is that a bad hash or other installation error causes Yarn to bail out and not properly clean up .yarn-metadata.json files.

I triggered this condition after a failed install of lodash.isfunction:

If you trigger this, you can workaround the issue with:

yarn cache clean

Then try your install again. In my case, the re-try worked.

jkingdon · 2017-04-17T20:44:12Z

We were getting this on yarn 0.22 (installed via npm). We resolved it by upgrading to yarn 0.23.1 (installed via apt) and then running yarn cache clean.

bestander · 2017-05-23T14:15:43Z

Should be fixed now

m4v0 · 2018-01-31T00:46:50Z

Set the problem with the command "native command-inactive "
After running the "yarn cache clean" command, it worked normally, thanks for the tip.

Musigwa-zz · 2018-03-05T17:12:52Z

anyone to help me???

bestander · 2018-03-05T17:38:49Z

@Musigwa, looks like your cache might be corrupt.
Try running yarn cache clean and then install again

Musigwa-zz · 2018-03-05T17:48:28Z

thank you i'm going to try it out

Musigwa-zz · 2018-03-14T08:46:24Z

Thanks at all it worked fine

This might help someone...perhaps, I might be needing it in the future.
It's not uncommon in this space...

I was having this issue while trying to work on a project that required using yarn. So I ran yarn and was receiving this error message:


yarn install v1.16.0

Thanks @bestander

MrGlaurung · 2019-09-27T06:14:59Z

Don't forget that if you get this error on windows it can be because you have an empty package.json in your home directory (C:\Users\yourlogin\package.json).

If you have the empty file there just delete it and you are on track again.

You really saved my life! I tried all possible things and hunderts of reinstalls... :-)

Thank you! This also solved my problem with yarn!

AmazingTurtle · 2020-07-10T12:03:57Z

I'm running the yarn install procedure within a Dockerfile, there's no cache. It's retrieving the dependencies directly from a registry. Why is this still a thing? Also I have seen this issue with icu4c-data/.yarn-metadata.json most of the time.

radiorz · 2021-05-17T07:48:38Z

thanks, yarn cache clean do helps me.

gepthecoder · 2022-05-14T08:36:58Z

In Windows first stop the development server and then try to install package.

danielrsantana-humaitrix · 2023-11-11T22:30:56Z

If you are unable to run yarn cache clean because of the same error, your package.json file is probably empty.
