An error occurs when executing apk build in android studio
After building normally, the app should be deployed, but a build error occurred and it does not proceed any further.
I want to run a react native app by those commands:
npm i -g expo-cli
expo init myapp
cd myapp

I added this to the path:
C:\Windows\System32
but I still get the error above
ok, that was the solution:
the problem was:
Error: spawn powershell ENOENT
so I need to add:
C:\Windows\System32\WindowsPowerShell\v1.0
to the path.
I openned Windows PowerShell as admin and run:
Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
run npm start again in the cmd and then metro boundler was openned
I did that commands yesterday but somehow it didnt work, guess I have missed something.

Anyone can please help me
solution 1 ---
First add powershell to PATH as %SystemRoot%/system32/WindowsPowerShell/v1.0.
open powershell as admin and write this command Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force.
last thing fire npm-windows-upgrade.
solution 2 ---
Add %SystemRoot%/system32/WindowsPowerShell/v1.0 to your PATH Variable,
cmd+q and search env and hit enter
click environment variables in the advanced tab
find Path/PATH variable and click edit
Click new and paste %SystemRoot%/system32/WindowsPowerShell/v1.0
click ok and restart your terminal and try installing again
I would like to create a re-usable react component library and for boiler plate i came cross create-react-library - https://www.npmjs.com/package/create-react-library.
I followed the steps to create new library using npx command and it was successfully.
I have discovered that i was unable to run npm run test but if i run eslint . on command prompt it works fine so not sure if getting this error.

I'm using MacOS Mojave 10.14.5. When I run 'npm run dev' command where the nuxt starter package is located, I have 'fsevents' error, and the server doesn't work.
I already reinstall node and npm several times, but it doesn't work.
Here's an error:
/Users/kimgyun/Desktop/nuxt_test_folder/nuxt_test_b/node_modules/watchpack/node_modules/chokidar/lib/fsevents-handler.js:28

How can I run this nuxt.js server without this error?
It's a problem with fs events, and a rather annoying one at that. Specifically this happens when you're using Node 12.
You'll need to install fsevents#1.2.9 explicitly:
npm i fsevents#1.2.9 -D
or
yarn add fsevents#1.2.9 -D
This should work for you at this point.
