Gatsby breaks with yarn 1.x

[ahmedelgabri]

After updating yarn, I can't build anymore. yarn 0.27.5 works fine but not 1.x. Here is the repo & this is the error I'm getting:

I just ran into the same error with yarn v0.27.5 😕 after I ran yarn upgrade.

yarn run v0.27.5

I ended up restoring my older yarn.lock and it resolved the error. I thought it may have been solved by downgrading to relay-compiler@1.1.0, but the yarn.lock in the repo you linked looks like it’s on that same version, too. 😞

[swim]

Looks like it's related to yarnpkg/yarn#4478?

[ahmedelgabri]

@swim it said that it was fixed in 1.1.0 which is the version I'm using & still having issues.

[KyleAMathews]

The relay-compiler error was fixed in core recently as their 1.3.x -> 1.4.x update broke us. The version is pinned now so if you upgrade to the latest Gatsby things should work.

FWIW, I've been using Yarn 1.x on my mac for the last few weeks without trouble.

[ahmedelgabri]

Updating to the latest version didn't fix the problem for me. I delete the node_modules & yarn.lock to generate a new lock file & still. Same error

[KyleAMathews]

This is any site? E.g. all the official starters fail?

[ahmedelgabri]

I linked to the repo I’m referreing to in my first post already. I didn’t try any starters.

[m-allanson]

I got the same error when trying to build Gatsby on the repo mentioned in the first comment using yarn 1.1.0. Here's the output from my terminal: https://gist.github.com/m-allanson/59c55ffb705246e4a69c2c7d9366031b

I didn't get any errors when I tried yarn install followed by yarn build on the gatsbygram and using-redux examples. (I'm new to Gatsby but have encountered a couple of similar errors to those mentioned above.)

[ahmedelgabri]

Ok, found the problem(s) & fixed it.

• gatsby-plugin-emotion now has emotion as a peerDependency, previously it was a direct dependency & was released as a patch so when I updated the plugin things stopped working.
• I had webpack installed as a direct devDependecy I think I forgot to remove it when I was experimenting with something. I think this was also the reason for the babel errors.
• Then I had a couple of missing ; in CSS when I used emotion's css prop.

My only request here is better error messages maybe & when a breaking change like this happen in one of the plugins maybe it should be released as major. The rest was some mistakes from my side.

[sebastienfi]

@ahmedelgabri I see the need for better error messages. Could you please detail what you would have needed to see and maybe PR on that ?

[ahmedelgabri]

@sebastienfi something more related to the issue, not sure what caused the babel error message. Maybe the installed webpack? if yes then maybe something related to this.

For gatsby-plugin-emotion I think the solution is in a proper versioning, the change was definitely not a patch.

[KyleAMathews]

the change was definitely not a patch.

Yeah, this was my fault. The recent PR with the changes should have been a v2.
