Hi there,

Any ideas?

Getting the same issue. Right now the cfn-lint extension is just not working. No errors are called out.

[kddejong]

@sviera91 and @ustrahlendorf have you installed cfn-lint from pip? https://pypi.org/project/cfn-lint/

There is a setting to configure the path to cfn-lint if its installed in a location that isn't included by your PATH environment variable.

Mostly looking at this line your output.
/bin/sh: cfn-lint: command not found

https://github.com/awslabs/aws-cfn-lint-visual-studio-code#extension-settings
cfnLint.path

Thanks @kddejong, problem fixed, cfn-lint had despaired because of some configuration changes around several python versions :-)
Done re-install through brew, works now for me.

[kddejong]

good news. Thanks @ustrahlendorf

[sviera91]

@kddejong Yeah same here. I just switched laptops and while I installed the extension forgot to install the library through pip. My bad :P Thanks for the help!

bundling cfn-lint itself seems like it would help with these issues as well

@DScheglov is this the issue you're running into? Does installing cfn-lint and making sure that executable is in your PATH solve your issue?
