I follow the [Getting Started](https://enigma.co/protocol/GettingStarted.html) 、 [Writing a Secret Contract](https://enigma.co/protocol/SecretContracts.html) 、 [Creating a React Front-End](https://enigma.co/protocol/CreateReactFrontend.html) , but I get this Syntax Error about _enigma\_dapp/client/src/App.js_ , I copy the [Creating a React Front-End](https://enigma.co/protocol/CreateReactFrontend.html) said App.js , Error follow the pictures ![10550711447793](https://canada1.discourse-cdn.com/flex035/uploads/enigma1/original/1X/acae9a6979fef58f0755f4421ce94c37958eb70c.png) ![10550715891778](https://canada1.discourse-cdn.com/flex035/uploads/enigma1/original/1X/08b976c2c7f71425013dfca81c22ff53143559c0.png) * * * if I didn’t add [Writing a Secret Contract](https://enigma.co/protocol/SecretContracts.html) 、 [Creating a React Front-End](https://enigma.co/protocol/CreateReactFrontend.html) part I get “Enigma setup still loading” ![10550885904564](https://canada1.discourse-cdn.com/flex035/uploads/enigma1/original/1X/1567f91a4f7f28c11f983de1de612cd2d765df34.png) I’m sure the /enigma\_dapp/ have package.json and /enigma\_dapp/client/ have package.json 、 package-lock.json 、 yarn.lock but /enigma\_dapp/client/src don’t have any of them , how can I fix the problem? ---

hey @ARsakura the docs which you refer maybe a very-early version of Enigma (still using Solidity for contract development). At the moment, you can follow 3 walkthrough parts [here](https://blog.enigma.co/developers/home). The testnet (called `discovery-cli`) now is easier to setup. Of course you need to install [Prerequisites](https://github.com/enigmampc/discovery-cli#requirements) before starting development. Just try again and let us know the result. ---

Okay , but both(this version and “discovery-cli”) are tested before , i show this error because the version have response , I will post the “discovery-cli” error message next post. Thank you , arookie. ---

@ARsakura, looking at the error itself, it says there is an error with your file at `/home/ar/enigma/enigma_dapp/package.json`. Can you post the contents of this file on this thread, so that we can identify what’s wrong with it? ---

Maybe it’s just the formatter here, or when you copied from elsewhere, guess it used to be `[]` You can try fixing or removing keywords, see if that helps or there’s another error, then paste the json here using the “Preformatted text” if you didn’t already. ---

Strange, but at least then it should be reproducible. If so please push your project to github with the steps you took then I’ll try reproduce it on my system too. ---

@ARsakura, checking in here: has your problem been fixed? as @taariq points out, there is something wrong in your `package.json` file around the `keywords` section. It should look like this one: [https://github.com/enigmampc/enigma-template-dapp/blob/9d88c815827bf14033ffef0083c1c76f049835b3/package.json#L9](https://github.com/enigmampc/enigma-template-dapp/blob/9d88c815827bf14033ffef0083c1c76f049835b3/package.json#L9) Can you double check, or copy it over again? and make sure that line equals this: ```auto "keywords": [] ``` Kindly let us know if this resolves your problem. ---

1.This is one of computer’s result ( it always get wrong ) Yes , My original document is： `"keywords": [] ,` I didn’t notice the last post is a square , sorry. and I delete the `[]` , now is： `"keywords": ,` I follow the @taariq 's way and restart again.(computer restart , too) and I got these errors. I launch the enigma\_network by `sudo ./launch.bash -t -s` and … I usually used `npx react-scripts start` because `npm run start` didn’t work , as follow： ![10635244442298](https://canada1.discourse-cdn.com/flex035/uploads/enigma1/original/1X/107e2595d32ccb636c90e8fbb72cdf2f7f7bf332.jpeg) Left is enigma\_dapp / Right is enigma\_network than I use the `npx react-scripts start` , as follow： ![10635261993638](https://canada1.discourse-cdn.com/flex035/uploads/enigma1/original/1X/34afa2234269f956e47f6f08911bfd3cb289e156.jpeg) Left is enigma\_dapp / Right is enigma\_network `---------------------------------------------------------------------------------------------------------` 2.Another computer is last one’s (the first post’s one) , I follow the @taariq 's way , and get the web： Enigma Template DApp Enigma Setup still loading… Nothing happend (including million problem contract not showing or something) `---------------------------------------------------------------------------------------------------------` I didn’t expect developer will reply my problem (Original situation) , and I not sure will keep this more far , it took me the whole 2 month for building it , and I won’t keep it. Probaly I will try discovery version , I just think it really ,always problems a lot for me , It wastes too much time. ---

Sorry you faced this but the repo was deprecated, so it would be great if you could try discovery instead. You’ll find it’s a much better development experience and if you have any issues we can work through it in the latest version. ---
