Question

No podspec found for React in ../node_modules/react-native
I am getting above error when i do pod install after successful npm install
NPM Version : 5.6.0
Below is the pod file text
# Your 'node_modules' directory is probably in the root of your project,
# but if not, adjust the `:path` accordingly
react_native_path = '../node_modules/react-native'
pod 'Yoga', :path => "#{react_native_path}/ReactCommon/yoga"
pod 'React', :path => react_native_path, :subspecs => [
'Core',
'RCTText',
'RCTImage',
'DevSupport',
'BatchedBridge',
'RCTLinkingIOS',
'RCTAnimation',
'RCTActionSheet',
'RCTWebSocket', # needed for debugging
# Add any other subspecs you want to use in your project
]
end

Answer 1

Check that file ../node_modules/react-native/React.podspec is really exists relative to Podfile. If not, check that you package.json really contain react-native as dependency.
For standard RN project directory structure, Podfile should be placed in <projectRoot>/ios/Podfile, and looks like:
platform :ios, '9.0'
target 'CGUI' do
pod 'React', :path => '../node_modules/react-native', :subspecs => [
'Core',
'CxxBridge',
'RCTAnimation',
'RCTBlob',
'RCTText',
'RCTNetwork',
'RCTWebSocket',
'RCTImage',
'RCTLinkingIOS',
'DevSupport',
]
pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
pod 'DoubleConversion', :podspec => '../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
pod 'GLog', :podspec => '../node_modules/react-native/third-party-podspecs/GLog.podspec'
pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'
pod 'RNDeviceInfo', :path => '../node_modules/react-native-device-info'
pod 'RNFS', :path => '../node_modules/react-native-fs'
pod 'RNVectorIcons', :path => '../node_modules/react-native-vector-icons'
end
This is for RN 0.51.0

Answer 2

after successful npm install,
delete the file podfile.lock in your project root dir,
then pod install in your project root dir.
this works for me.

Answer 3

Go to your project directory
in IOS write command in terminal to open Xcode
open ios/[projectname].xcworkspace
and open Pods folder from the left navigation bar and open Profile file
after that remove the line,
pod 'RNVectorIcons', :path => '../node_modules/react-native-vector-icons'
and rebuild project.
