Keter setting up file is not working

[fmarquez199]

I'm trying to setting up keter in my server but I got this:

cp: cannot stat '/root/.local/bin/keter': No such file or directory

I also have the exact same issue. When looking at the content of "https://raw.githubusercontent.com/snoyberg/keter/master/setup-keter.sh" it seems that the start of the sh file is like this:

#!/bin/bash
mkdir -p /opt/keter/bin
cp ~/.local/bin/keter /opt/keter/bin

mkdir -p /opt/keter/etc
...

Am I missing some obvious thing, or is the sh script wrong?

[lucch]

Indeed, it looks like the setup script expects a keter binary to be already available at ~/.local/bin.

I haven't used that script myself, since it is not recommended for production environments, so I would recommend you to build Keter using Stack, and then copy the binary and configuration files to your server.

See this: #200 (comment)

[mmzx]

I personally have not used this script to set keter up. It would be helpful if you could verify the existence of the mentioned path in the error message and knowing/checking whether the permissions are sufficient would be necessary also.
BTW, assuming you wish to use keter for Haskell related project: the path ~/.local/bin/keter, could refer to a cabal (legacy) installation folder. - I am not sure whether that is relevant in your case.

[benjamingoldstein]

Thank you @lucch and @mmzx for your responses. The file ~/.local/bin/keter is missing, because I have not installed keter. I made a PR for changing the instructions on the README.md. I will try to install keter with stack. If I get it all working, I will update the instructions further.

[mmzx]

stack should work, have you had an issue using a very recent ghc, let us know here. You could also have a look at the CI setup in case resolvers and/or ghc versions are interesting in your case.

[benjamingoldstein]

Thank you @mmzx

I'm on a brand new server.

I just installed stack by copying and pasting the curl install command from the main haskell stack website. It worked.

I just ran stack install keter and it didn't work.

You said to let you know here, if there is some used related to GHC versions, is this error what you mean? (See the later error message below)

$ stack install keter

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for keter-1.4.3.2:
    http-reverse-proxy-0.6.0 from stack configuration does not match >=0.4.2 && <0.5  (latest matching version is 0.4.5)
    unix-compat-0.5.2 from stack configuration does not match >=0.3 && <0.5  (latest matching version is 0.4.3.1)
    yaml-0.11.5.0 from stack configuration does not match >=0.8.4 && <0.9  (latest matching version is 0.8.32)
needed since keter is a build target.

Some different approaches to resolving this:

  * Set 'allow-newer: true' in /home/ubuntu/.stack/config.yaml to ignore all version constraints and build anyway.

  * Recommended action: try adding the following to your extra-deps in /home/ubuntu/.stack/global-project/stack.yaml:

- http-reverse-proxy-0.4.5@sha256:7f2a181ec848e8fdc0bdb4d6e775e488897957ee7ae0a2b82a623360168ccf96,2528
- unix-compat-0.4.3.1@sha256:a291f209e9c9723204c49c978ed2c53997dbc9666e53fe7bf7a3548b2c8bb22c,2030
- yaml-0.8.32@sha256:cb9e788e4c18f3c3579a950c1d53f89efb7e8871f6a00b5fabc37084c05cf04e,5452

Plan construction failed.

I tried to follow the "Recommended action" by pasting those three lines to the end of the file /home/ubuntu/.stack/global-project/stack.yaml but I think I've done it wrong, because it's invalid syntax.

People want instructions that they can just copy and paste, run and get it working.

If I manage to get this working, I will update the instructions on the README.md so that others can just copy paste and get it working.

I tried to edit the config again with a different syntax, just guessing at it. I had to add a line "extra-deps" first, and then some whitespace, and then the suggested lines.

Now I run stack install keter and I get a different message:

$ stack install keter

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for yaml-0.8.32:
    base-4.13.0.0 from stack configuration does not match >=4.9.1 && <4.13  (latest matching version is 4.12.0.0)
needed due to keter-1.4.3.2 -> yaml-0.8.32

Some different approaches to resolving this:

  * Set 'allow-newer: true' in /home/ubuntu/.stack/config.yaml to ignore all version constraints and build anyway.

  * Build requires unattainable version of base. Since base is a part of GHC, you most likely need to use a different GHC version with the matching base.

Plan construction failed.

I am stuck. Sorry for the long message.

Thank you both for your help

[benjamingoldstein]

It sounds risky to do the "Set 'allow-newer: true' ".

But I did it, and the stack install keter now fails with an error in the yaml package, which is the one with the version dependancy issue.

I just tried removing the extra-deps: and just tried with only "Set 'allow-newer: true' ".

Now there is the issue in #170

I give up, I will just try to use nginx instead of keter.

[mmzx]

I've no idea about your local setup, but this just works fine if you prefer using stack:
stack build --stack-yaml stack_lts-1319.yaml

There is always the #195
