Unknown file extension ".CMD"

[IvanAnikin]

I’m running into this issue when running “npm run dev:emulator” in main directory of the https://github.com/onflow/kitty-items repository after running ‘npm install’:

TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".CMD" for C:\USERS\30407792\CODE\FLOW\2\KITTY-ITEMS\NODE_MODULES.BIN\NPM.CMD

Thanks in advance

Hi, it may be a node/npm installation issue but hard to debug from here. Can you give more details about your current setup? Please run npx envinfo and paste the output here.

Thanks, I tried installing the packages separetely in different folders with npm install and yarn install and running it with the yarn or npm in each directory, but the error was always the same.

I'm experiencing this same error on a Windows laptop after executing npm run dev:testnet and pasting the faucet address.

The program prints the Kitty Items has started in multicolor and then it crashes printing these logs:

I'm getting the same issues... anyone find the answer? Maybe port issues?

[sonerakinci]

OMG. There is no answer for this critic error. I took same error but there is no solution for 2 months.

As a workaround , you can launch api and web manually. ( after contract is deployed )

For Testnet:

• npx dotenv-cli -e .env.testnet -- npm run dev --prefix api
• npx dotenv-cli -e .env.testnet -- npm run dev --prefix web

For Emulator

• npx dotenv-cli -e .env.emulator -- npm run dev --prefix api
• npx dotenv-cli -e .env.emulator -- npm run dev --prefix web

• npx dotenv-cli -e .env.emulator – npm run dev --prefix web

I'm getting the following error when trying to input the above commands.

npm ERR! arg Argument starts with non-ascii dash, this is probably invalid: –
'–' is not recognized as an internal or external command,
operable program or batch file.

I've typed it in manually as well, which still gives an error. Has anyone had success with this?

[bluesign]

@AttackOnSight updated the comment, double dash merged somehow, can you try again?

[AttackOnSight]

@bluesign Thank you for the help. Everything seems to work fine for this issue now with the updated commands.

Just a tip for anyone else who might come across this later issue, it seems like the Opera Crypto Browser is having some trouble when minting as an Admin (it just loops without creating the NFT), but switching to Firefox solved that issue.

[AttackOnSight]

@bluesign sorry for the reping, hopefully you can help me with this error when trying to launch the API for emulator, I am getting this error on the console.

That is because pm2 can not recognize the 'npm.cmd' command, referring to here.
An easy solution is to change the two npm in .ki-scripts\startup.js to <npm-cli.js location in you windows computer>, like this:
await runProcess({ name:web, cwd: "./web", script: C:\Program\ Files\nodejs\node_modules\npm\bin\npm-cli.js, args: "run dev", watch: false, wait_ready: true, autorestart: false });
