Create-react-app: Create react app dependency error

[sumit-raikar]

Note from Maintainers:

If you're having this issue please roll back npm to a version without this bug:
npm install -g npm@4

---

When i try to create a new react application using create-react-app, it tries to download fsevents but fails ,also gives Error: Can't find Python executable "python" and Error: Failed to execute 'node-gyp.cmd configure errors. I have attached the screenshot. Thank you in advance.

[abdellah-el-mennani]

same error in the instalation it gives me:

warning [email protected]: The platform "win32" is incompatible with this module.
info "[email protected]" is an optional dependency and failed compatibility check. Excluding it from installation.

[deehuey]

+10 fucking million.

I have been trying to debug this all morning. Only just started happening to me. NPM version is 5.0.3

Can somebody please find a solution.

[viankakrisna]

fsevents should only be installed on osx. I think it's a bug with npm@5 https://github.com/mapbox/node-pre-gyp/issues/298
can you all try with npm 4 / use the proposed workaround (deleting and disabling package-lock)?

[Timer]

I have a feeling the recently merged #2550 will solve this in the next release.

Can someone please try downgrading to Node 6 or 7 to see if this persists for them?

[abdellah-el-mennani]

I think this issue is related to Webpack, when I tried to create my own boilerplate without using create-react-app, the issue appears when I tried to add Webpack

[Fea-Sin]

I have the same problem, enviroment win7 64bit, create-react-app version : 1.3.1. what ?

[9minimart]

I have same problem.

• node 8.1.2
• npm 5.0.3
• create-react-app 1.3.1

I try to downgrade npm to npm 4 latest.
I have no problem.

[abdellah-el-mennani]

I downgrade to node 6.11.0 and npm 4.6 but the issue still there

[UNDERCOVERj]

+1。and i install react-router, then the issue still there

[gaearon]

cc @thelarkinn, any ideas what happened? We didn't change anything on our side.

[kylelamse]

Same issue for me.

• node v6.11.0
• npm 5.0.3
• create-react-app 1.3.1
• windows 10

[abdellah-el-mennani]

The exact error it gives me after running yarn start is:

yarn start v0.24.5
$ react-scripts start
module.js:471
    throw err;
    ^

[gaearon]

Try:

• Removing package-lock.json if you have one
• Removing yarn.lock if you have one
• Downgrading npm to 3.x if it's newer
• Run npm install
• Then run npm start

Does this help anyone?

[kylelamse]

@gaearon are you suggesting that just to diagnose the issue? Because I think it would be inconvenient to be forced to use an old npm...

[gaearon]

Changing npm version takes a few minutes in my experience. npm@5 is known to have a lot of bugs, and I want to figure out if at least some cases are caused by npm@5 or not.

[gaearon]

I just tried with npm@5 and I saw the error noise (although eventually the installation finished successfully for me). In the meantime I recommend downgrading: npm i -g npm@4.

[gaearon]

I'm fairly sure it is this npm bug: https://github.com/npm/npm/issues/16810.
Unfortunately there's nothing we can do until it's fixed.

If you're having this issue please roll back npm to a version without this bug:
npm install -g npm@4

If you still have a problem after downgrading npm please file a new issue with screenshots and details about your system.

npm install -g npm@4 it works, thanks very much

[mnemanja]

I've managed to make it work with the following setup:

node - v6.10.0
npm - v5.0.4
react-scripts - 1.0.10
os - win10

After the update to 1.0.10 I've also updated the react and react-dom versions to v15.6.1, I've deleted the package-lock.json and deleted the node_modules and re-installed the dependencies and then everything started working as it should be.

Hope this helps.

[medeirosrich]

For me this worked:

• delete package-lock.json
• npm i -g npm
• npm install

[VenkateshManohar27]

npm install -g npm@4 works, thanks a lot :)
