[lionroy]

Hi y'all!

trying to compile this react app [ build via crete-react-app] and figuring styled-components is rather useful. worked fine last i checked. compiling error statrted after have installed babel as recommended in their babel site.. kinda normal i guess.

for >$ yarn run build
I get this -
yarn run v1.3.2 $ react-scripts build 'react-scripts' is not recognized as an internal or external command, operable program or batch file. error Command failed with exit code 1. info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

also -
for > $ yarn start
yarn run v1.3.2 $ react-scripts start 'react-scripts' is not recognized as an internal or external command, operable program or batch file. error Command failed with exit code 1. info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

this is the error file generated-
yarn-error.log

• [v ] I've asked for help in the Mist Gitter before filing this issue.

Yarn Version: `1.3.2`
OS & Version: windows/linux/osx
Node version: `geth 8.9.2`
Number of blocks synchronized: 0

Hey there. I'm not sure if you opened this issue in the wrong repo, but Mist is not a react app (nor a create-react-app). It is a hybrid meteor-react app right now, but we are slowly converting it over to all react.

ryanio - to be honest not sure what do you mean, about issue and repo
I logged to Mist and asked, in a create-react-app room. yet then. there was that. :)

Solved.

Here's how. sorta. so-
PROBLEM - it seems installing babel changed many nodes, yet it did NOT update the yarn.lock and package.json files accordingly.
SOLUTION -
$ yarn info |> made me realize some 2k files are out of date
then ran
$ yarn upgrade |> and it somehow sorted it but didn't compile yet
then
$ yarn add yarn |> to actually update yarn as it was 1.3.x and required 1.7.x

i think that's it yet, may have skipped a step or two... better read more about the cli commands i suppose.

its not working for me
Still have the error : error An unexpected error occurred: "Cannot read property '1' of null".

i resole the problem when i edit webpack.config.js ( i remove the addStyleEntry )

I received the same error as Franklin-Graciliano did.

package.json
public
src

Either try using a new directory name, or remove the files listed above.

Sorry but that link shows nothing related to error code 1, only shows some yarn codes

worked for me too

One of the issue that you may face is the server won't start if some other server is running too .
For eg. I had XAMP Running and thus my yarn couldn't start itself. Check it once.

(Mac) In my case, I had this problem after cloning a repo from my work project, what I had to do was 'cd ios' and run 'pod install' inside there. After this I was able to build my local copy of the project. Hope it helps someone

I was facing error, I use command yarn install and then yarn upgrade, now its working
