Getting error for yarn command

[nachiketdeore09]

In lesson 5 at 6:54:24 this yarn command

yarn solcjs --bin --abi --include-path node_modules/ --base-path . -o . simpleStorage.sol

is giving error as

warning package.json: No license field
$ /Users/nachiket/Desktop/practice/Blockchain/node_modules/.bin/solcjs --bin --abi --include-path node_modules/ --base-path . -o . simpleStorage.sol
Error reading simpleStorage.sol: Error: ENOENT: no such file or directory, open 'simpleStorage.sol'
error Command failed with exit code 1.

can someone help me with this?

Maybe check your contract file name.
Is it SimpleStorage.sol (started with uppercase S) or simpleStorage.sol (lowercase s)?
The command input must be the same as your file name.

Hope this help.
