npm-install
How about reinstalling the node module? Go to the root directory
of the project and remove the current node modules
and install again.
These are the commands : rm -rf node_modules npm install
OR
npm uninstall -g react-native-cli
and
npm install -g react-native-cli
For ng9 upgraders:
npm i -g core-js@^3
..then:
npm cache clean -f
..followed by:
npm i
With this
npm install --save core-js@^3
you now get the error
"core-js@<3 is no longer maintained and not recommended for usage due to the number of
issues. Please, upgrade your dependencies to the actual version of core-js@3"
so you might want to instead try
npm install --save core-js@3
if you're reading this post June 9 2020.
For npm
npm install --save core-js@^3
for yarn
yarn add core-js@^3
Install
npm i core-js
