Library file 'microevent.ts' not found.

@graphprotocol/graph-cli

Describe the issue

Note: This bug seems to only appear on Windows, I tried with the same environment on Ubuntu, it worked file.

When trying to build a subgraph, this error appears: Library file 'microevent.ts' not found..

I tried to trace back the issue a bit:

It seems to be linked to AssemblyScript and the custom defined libs at line 626 - 646 in: node_modules/@graphprotocol/graph-cli/node_modules/assemblyscript/cli/asc.js.

At line 643 inside of that file, it tries to read the microevent.ts library as a file with fs.readFileSync() inside of the node_modules, so of course, it returns null and prints the error.

Reproduction

Steps to Reproduce the Bug or Issue

1. Cloning an existing subgraph
2. yarn install etc..
3. Run the codegen command.
4. Run the build command.

Expected behavior

Expected the subgraph to build fine.

@Corantin @yoratoni to confirm this is an issue only on Windows 10?

Yeah, I switched to a sublinux environment (WSL) ^^

Yeah definitely, I switched to WSL after not being able to solve the issue and it works perfectly fine now.

I've got the same issue, on Windows 10 as well with [email protected] and [email protected] Just downgrade graph-cli to the previous version I used ([email protected]) and the problem disappears
