I would like to contribute to this issue by stating the steps to successfully run this decentralized application of (ipfs_image_uploader) and also the code as per the updated versions. Step 1: Clone this repository to you system with the help of git clone command. Command - "git clone https://github.com/dappuniversity/ipfs_image_uploader.git " Step 2: Now to download all the dependencies of the project run this command. Command - "npm install" Step 3: After installing all the dependencies of the project now we have to compile the smart contract. Make sure you have your Ganache up and running. Step 4: Before compiling we have to make some changes in the 'truffle-config.js' file, we have to un comment the deployment code and put in the details of Ganache which you are using.

development: {
     host: "127.0.0.1",     // Localhost (default: none)
     port: 7545,            // Standard Ethereum port (default: none)
     network_id: "*",       // Any network (default: none)
    },

Step 5: After making this changes we have to go to truffle folder and run this command.

- Contracts: Compile:         cd truffle && truffle compile
- Contracts: Test:                cd truffle && truffle test
- Contracts: Migrate:         cd truffle && truffle migrate

Step 6: After successfully compiling the smart contract now we should the run the frontend of the application

- Dapp: Run dev server:         cd client && npm start
- Dapp: Test:                           cd client && npm test
- Dapp: Build for production: cd client && npm run build

By following all these commands your application will be up and running.
