Resolved it by adding C:\Windows\System32\ to path variable then restarting computer.

Hello,
Anas Ahmed here, I was installing bugsnag-expo-cli-init in my react native app at first it asked me 3 ques and then at the time of installing it gave me this error can anyone help me in this. Installing in npm
Are you attempting to run the bugsnag-expo-cli on Windows? Bugsnag's Expo CLI currently only supports Linux and Mac:
https://docs.bugsnag.com/platforms/react-native/expo/#installation-and-configuration
As an alternative to the CLI, you could follow the manual integration guide:
https://docs.bugsnag.com/platforms/react-native/expo/manual-setup/
my english isn't that good. I am from Turkey and sorry if my question isn't clear to you.
When I run run-android with React Native, I get the following error but when I run run-ios I don't get any issue. I am using a Mac computer.
Thank you for your help.

I think you should uninstall the app on any emulator or devices, after that please re-run app.
It might be caused by having package.lock.json and yarn.lock at the same time
I'm on Windows 10 Version 10.0.16299 Build 16299. I'm using Powershell. I just used yarn global add expo-cli to install expo, then I ran expo init my-app then cd my-app and expo start, but the build is failing. Here's the error image and text:

Any ideas? Or even suggestions on another place where I can post this issue since it's failing out of the box. All help appreciated.
For windows:-
add environment variable in
set Path - C:\Windows\System32\
after setting path. restart your computer.
In my case, I added C:\Windows\System32\

I have installed a new react native project using create-react-native-app. When I do yarn start or npm start and scan with expo, it gives me the following error in ubuntu (when remote js debugging is on).

Stopping packager...
Packager stopped.
Done in 701.25s.
But its not the case with windows(it opens the debugger in browser).I guess in ubuntu It tries to launch debugger in browser, but somehow fails to do so. I followed some links but none of them helped.

Run yarn or npm without sudo, because when you enable devtools it's tries opening chrome by command (chrome won't open with sudo)
You can do it open google chrome and hit this url http://localhost:8081/debugger-ui
open console tab to debug
Disable Chrome cache
Right-click chrome
Go to 'inspect element'
Look for the 'network' tab somewhere at the top. Click it.
Check the 'disable cache' checkbox.

I get the error shown below every 3-5 times I reload the iOS app for React Packager. When restarting Xcode with that error, I see this in the packager window:
"login: fork: Resource temporarily unavailable
[Process exited - exit code 1]"
The above will not even allow opening any terminal on the Mac.
The only way to make it work is to REBOOT the machine (Running OS X 10.10.5, react-native 0.10 stable and also 0.11 stable)

Try updating to the latest version of Native.
Also, if you are running your sim in xcode, you can clear the cache of your project by using command+shift+k with the project stopped.
See if this clears it whenever you have the problem.
I installed latest version of react native, then uninstalled iojs. I installed latest Node.js and everything now works.
