[Error] Parsing solidity version in a range

[thanhtoantnt]

• Example: pragma solidity >=0.4.21 < 0.6.0;
• Error: ValueError: Invalid NPM block in '>=0.4.21 < 0.6.0': '<'

It's a bug of python-semanticversion.

It doesn't allow whitespace between < and 0.6.0.

@thanhtoantnt: can you fix the bug on the benchmark first?

We can fix on solc-detect or raise an issue to node-semver later.

[thanhtoantnt]

@taquangtrung you mean to change the pragma in the test case if it has the solidity version like this?

[taquangtrung]

Yes, we can temporarily fix the benchmark to: pragma solidity >=0.4.21 <0.6.0;

This is an incompatibility between the semantic versioning of Solc and Nodejs.

[taquangtrung]

The issue with whitespace was discussed here: rbarrois/python-semanticversion#127

But it seems the author's response is slow.

[taquangtrung]

@thanhtoantnt: you shouldn't close this issue, since we haven't fixed it in this repo.

[taquangtrung]

Anyway, I just fixed it in this commit: e74324b

So now it can be closed
