I installed expo using the facebook guide by running
npm install -g expo-cli
npm install react-navigation
expo start
However it still says

I tried to delete my node_modules folder and rerunning npm install in the directory of my project
It still says react-native not found, although running
react-native -v
in command line, shows
react-native-cli: 2.0.1
react-native: 0.60.3
Actually you have only install expo-cli not react native cli , even if your package.json has react-native it is not accessiable from your cli . so you have to install react-native-cli seperately so that you can access react-native.
npm install –g react-native-cli

Been trying to install jest with this command:
npm i --global jest
and get these messages:

Have tried manually installing peer dependencies with:
npm i --save --global canvas#^2.5.0
npm i --save --global bufferutil#^4.0.1
npm i --save --global utf-8-validate#^5.0.2
but still am unable to install jest.
How do I install jest?
EDIT: Forget about the global install and the peer dependency warnings go away, but I still get:
-bash: jest: command not found
Since I seemed to have a prior installation of nvm that kept installations of different versions of node in different directories, I decided to start fresh.
Uninstalled and deleted jest, node, npm, and nvm.
Reinstalled node/npm, and was able to install jest and get the jest -v command to work properly.
I have tried nearly all solutions however nothing has worked for me. i cloned a repo from a friend and tried to run the client directory. When i try run client, i get the error:
Cannot find module 'webpack-cli/bin/config-yargs'
Cannot find module 'webpack-cli'
Once i cloned the project i did npm install (as it said in the readME) but when i tried to run the client i would run into this problem:
solutions i tried:
npm install -g vue-cli
npm install --save-dev webpack
npm install --save-dev webpack-cli
i tried 'webpack --version' it will tell me i am missing something and if i want to install it. i click yes and i get the following error:

UPDATE:
My colleague updated some of the dependencies by GitHub bot and i pulled the repo. That seemed to do the trick

These are not errors, they are just warnings that you need to install the sub-dependencies of the given package yourself. React Navigation is installed successfully in this case and you can use it fine. You can try doing npm audit fix which will try to fix these warnings by installing the dependencies.
I'm new, and I'm lost because I think I messed up my whole program. I cannot install anymore node variations. I'm using Visual Studio Code. And after the code below I typed "npm uninstall npm" thinking it would fix it, but it seems not.
I tried npm uninstall npm and it didn't work. :/

Can someone tell, how to resolve these warnings and uninstall react-native-maps?
Make sure you have react and react-native modules installed. The message format WARN react-dom#15.5.4 requires a peer of react#^15.5.4 but none was installed. tells you that react-dom needs react but react is not present.
You also need to make sure you install the proper version of react and react-native.
Try to use
react-native unlink react-native-maps && yarn remove react-native-maps.It will remove all the related packages in android & ios folder also.
