yarn install doesn't work on windows 10

[findjonmos]

I basically get the below errors, I have hunted around the web to try and find out specifically whats wrong but at a loss for the moment. Paid a lot for the course and cant get started

[toddmotto]

Hey Jon - looking into this. I think it also has something to do with the dependency on Node.js. I think a lower Node version would solve it, but will check this out now on my machine.

Wow! Thanks for the super fast response Todd. I will also test and see

[toddmotto]

A few others have reached out today (coincidentally) so either something globally's being strange or everyone on Windows is having Node issues with this setup! Will report back shortly. :)

Brill! Thanks Todd :)

[findjonmos]

It seems like your thinking on the issue was spot on Todd! I dropped back a whole version (node 7.10.1) and all works. I could probably try going up a few versions but I'm too keen to crack on with learning for now :)

[toddmotto]

Someone else has confirmed this - I've added a temporary note to that Installation video lesson for others - will check out what we need to fix this for users. Will keep the issue open! :)

[StrangeCargo74]

I had this problem. Starting the course and coming crashing to a halt is not a good experience! For me, changing my node version wasn't an option.

I think the install needed a pre-built package (or something) that wasn't available, and so tried to rebuild it. That failed because node-gyp and its prerequisites were not installed. I think.

So, with elevated privileges I installed

npm install --global --production windows-build-tools

and then i did

npm install --global node-gyp

and then added python to my environment variables:

set PYTHON "%USERPROFILE%.windows-build-tools\python27\python.exe"

and then the yarn install worked.

..bit of a faff tho!

[zaheer-d]

this worked for me. only had to change this line set PYTHON "%USERPROFILE%.windows-build-tools\python27\python.exe" -> set PYTHON "%USERPROFILE%\.windows-build-tools\python27\python.exe" notice the "\" after %USERPROFILE%

[mjangir]

I had the same problem and found one easy solution without degrading my node version.

1. Go to python download page and install python 2.7 from the downloaded installer.

2. Then open the command prompt with administrator and type the following npm install --global --production windows-build-tools

3. Then run npm config set msvs_version 2015 --global

Close all cmd instances and run npm install again in your project and you are good to go.

[sanpan1234]

I am facing the same issue trying to yarn install. It's a lot of hoops to go through just to get the base project running. Installing ye-olde legacy version of Python? really??

[Braybrookr]

I have messed around trying to get this up and running. My seed project now builds but when i open localhost:4000 there is no Hello!. It is just a blank white screen.

--edit: got my hello to finally appear. re-did everything from start with both 7.10 and windows-build-tools. Also used 2.7rc15 python.

for anyone else having issues .

[sanpan1234]

Just created my own base project using CLI. The only downside is I need to now run the json-server on a separate port but that's easier than struggling with this.

[tayelno]

try my solution here #11

Here is my machine settings, High Sierra v10.13.4 , Darwin x64.

$ node -v v10.0.0

$ npm -v 5.6.0

$ yarn -v 1.6.0 So what I did was simple, just remove the locked dev-dependencies of node-sass and sass-loader from package.json then simply run:

yarn add node-sass sass-loader --dev fixed everything for me.

here check my fork of the project, this commit shows the diff in my package.json

dependencies fix

I hope this fix it for you as well.

[percipio]

Awesome, this worked for me!

following StrangeCargo74 from above worked for me

[eakoning]

I just installed Node v8.11.2 (with npm v6.1.0) and did a yarn add node-sass@4.5.3. Now yarn install works.

[omarzahidwavelet]

Thanks @eakoning Your method worked. Why did it worked though? I mean what was wrong before. I don't get it. I am still getting this warning though: sass-loader@4.0.2 has incorrect peer dependency node-sass@3.4.2

But it is compiling and everything is working.

[eakoning]

@omarzahidwavelet I found this Stackoverflow post indicating there's a compatibility issue between certain versions of node and node-sass.

[omarzahidwavelet]

Thanks @eakoning, Cheers.

Hi @toddmotto, I am facing this below issue while trying to start the app by "yarn start" command. Please let me know some solution to run the application.

[markbell2410]

This worked @StrangeCargo74 - Just add a backslash after %USERPROFILE%

Remove the node_modules folder and re-run yarn

[markbell2410]

That's normal. It's a single page application so you would handle the 404 in the app

[nick20201]

I had the issue Downloading binary from https://github.com/sass/node-sass/releases/download/v3.13.0/win32-x64-72_binding.node Cannot download "https://github.com/sass/node-sass/releases/download/v3.13.0/win32-x64-72_binding.node": HTTP error 404 Not Found

The fix is to change node-sass to the latest version: "4.14.0"

[ghost]

I had the same issues with my Windows10.

1. I was running node-v16.3.0-x64.
2. I uninstalled it,
3. Then installed a previous (but supported) version: node-v12.22.1-x64.
4. Reinstalled npm at the command line: npm install -g npm
5. Which gave me the npm version 7.18.1
6. Finally, I followed the setup instructions to install yarn: npm install -g yarn Of course I was able to issue my project commands of 'yarn install' and 'yarn start'... Everything Worked!!! Hooray!!!

[kachiuli]

Just do the following in package.json before yarn install:

delete the line "node-sass": "^4.9.0", add the line "sass": "^1.35.2",
