Couldn't find a package.json ... when install react-scripts

[schovi]

1. Having empty new directory
2. Init new package.json (tried with yarn and npm)
3. add react-scripts package (can be added manually into package.json, but it does not matter)
4. Getting error: error Couldn't find a package.json (or bower.json) file in /Users/schovi/tmp/xxx/node_modules/react-scripts/node_modules/autoprefixer

15:51 $ mkdir ~/tmp/xxx && cd ~/tmp/xxx
~/tmp/xxx
15:51 $ yarn init
yarn init v0.15.1

Please retest with yarn 0.16.+, I'm unable to reproduce the error now.

version is really 0.16.0

[torifat]

Weird! works for me. I'm using the same version 0.16.0. Node v6.9.1 & macOS 10.12.

[schovi]

Solved! yarn cache clean helped. Not sure how broken version get there.

This might help someone else who stumbles across this page - I had this error when my directory/package.json didn't have the right file permissions

[jalavosus]

@joe4mg, what permissions does the package.json need?

[philpoore]

I was also finding this issue.
@schovi yarn cache clean didn't fix the problem for me.

Was running version v0.27.5, fairly out of date.
Upgraded yarn to latest version v1.5.1 via brew with:

brew upgrade yarn

And that fixed it.

package.json resolution works in sub-folders again.

yarn cache clean didn't solve my problem (couldn't find package,json file). But running it as administrator (-@windows) did.

My case was that I was not in the right folder when I run yarn. I had another folder inside the folder where I tried to run yarn start. The project files were in the other folder nested.cdto the correct folder and run yarn start - This worked for me.

[lalaphoon]

In my case, I just went to a wrong directory - the parent directory of my react project.
So just make sure in the directory where you contains your react project.
(Yes, I guessed. My comment will be downvoted.)

cd your_react_app
then
yarn start

[mali30]

just ran into this issue also. make sure your in the same directory as your package.json.

[magaldistudio]

[AtikRhaman]

For me, I wan in the wrong folder, cd to the right project and yarn run develop

[abdifatahmohamad]

cd your_react_app
then
yarn start

Thank you, it did work for me.

[freshmurry]

yarn add package.json worked for me

[GustavoMori]

When you create a new project with "yarn create ..." you aren't in the correct folder, so cd (name of project) then yarn start :)

Meu caso foi que eu não estava na pasta correta quando executo yarn. Eu tinha outra pasta dentro da pasta onde tentei executar yarn start. Os arquivos do projeto estavam na outra pasta aninhada . cdpara a pasta correta e execute yarn start - Isso funcionou para mim.

Obrigada por compartilhar essa informação, resolveu meu problema!
