Thanks for reporting this, will check it out.

[rahulmutt]

@ChinaXing Are you behind a proxy? We had someone report a similar error and running either etlas --http-transport=wget update or etlas --http-transport=plain-http update should work.

[adal-gibson]

I'm getting this same error - I'm on macOS 10.13.3 and when I try to compile a program or update etlas I'm getting the message:

  etlas: Could not read index. Did you call 'checkForUpdates'?

I tried both etlas --http-transport=wget update and etlas --http-transport=plain-http update but I got the same error both time.

[jneira]

Hi @madeleinergibson , could you share the output of etlas --version && etlas update -v3 (with -v3 the output should be more verbose)

[adal-gibson]

@jneira Sure thing!

[jneira]

@madeleinergibson i think that etlas version have a problem with the update, could you download the latest stable version (1.2.0.0) from https://eta-lang.org/docs/eta-concepts/getting-started/install-eta#binary-installation and try again?

[adal-gibson]

@jneira I couldn't get that to work either, unfortunately! Same exact error message.

[rahulmutt]

@madeleinergibson You're not behind a proxy right? Can you share the etlas update -v3 output with etlas-1.2.0.0?

[xmonader]

[rahulmutt]

If possible, can you install nslookup? @NickSeagull might know how to do that on Arch.

[xmonader]

It worked before installing dnsutils
but for reference : pacman -Ss dnsutils

[rahulmutt]

@xmonader reports that installing nslookup worked for him. We should either remove the dependency on nslookup or add it to the docs that you need to have it installed.

[naderghanbari]

I'm having the same problem with etlas version 1.2.0.0 on macOS 10.14. I installed etlas using homebrew: brew install typelead/eta/etlas and nslookup is available on the PATH.

output of etlas update:

Downloading the latest package lists from:

etlas: Could not read index. Did you call 'checkForUpdates'?

Update:
Everything works fine when I download the etlas binary. Problem happens only when installing etlas with homebrew, so perhaps I should report to the formula repo.

[Arpple]

having this problem on wsl ubuntu
the command I run before this happen

Welcome to Etlas, the awesome build tool for the Eta programming language!

We are working hard to make the best platform for pure functional programming
on the Java Virtual Machine.

Etlas will periodically send usage statistics to help us:

* Make decisions on how to evolve the language

* Build a community portal that displays the data we collect in visual form

* Build an Etlas package repository that will accurately display package popularity

* And more!

For more details, please consult our privacy policy:

Would you like to help us make Eta the fastest growing programming language,
and help pure functional programming become mainstream? (y/n)

@Arrple does this happen consistently?

@rahulmutt for when I tried, yes it happen consistently, I removed ~/.etlas ~/.eta and then update serval time
but now after I tried it again, still not work but the error seem to be different

[rahulmutt]

So I found a slightly similar error with another Haskell app: reflex-frp/reflex-platform#293. It turns out it's a problem specifically with WSL and it may be fixed by upgrading.
