Contracts in my contracts folder have no problem finding things like

• import "@openzeppelin/upgrades/contracts/Initializable.sol";
  

or

• import "@openzeppelin/contracts-ethereum-package/contracts/token/ERC20/IERC20.sol";
  

• import "@openzeppelin/contracts-ethereum-package/contracts/token/ERC20/StandaloneERC20.sol";
  

• import "@openzeppelin/contracts-ethereum-package/contracts/ownership/Ownable.sol";
  

•  import "@openzeppelin/upgrades/contracts/Initializable.sol";
  

but it seems that the contracts in @openzeppelin/contracts-ethereum-package/contracts can't find each other. See first few error messages at bottom.

It must be something simple but I've followed the instructions at https://github.com/OpenZeppelin/starter-kit-tutorial exactly several times and can't change the result.

Thanks in advance!!!

I’m sorry that you had this Issue.

You can try the following work around:
Running on Windows Subsystem for Linux (WSL)
https://forum.openzeppelin.com/t/solidity-smart-contract-development-on-windows/2110

I run WSL with node 10.

I was able to reproduce with the following steps:
On Windows 10
Node v12.14.1
After unpacking the Tutorial starter kit, run: npx oz compile
