Hub: Go command not found

[adl1995]

I have Go installed on my system (Ubuntu 14.04), and the $PATH is correctly set up. When I give the command go on my terminal, I get this:

Go is a tool for managing Go source code.

Usage:

    go command [arguments]

The commands are:

    build       compile packages and dependencies
    clean       remove object files
    doc         show documentation for package or symbol
    env         print Go environment information
    bug         start a bug report
    fix         run go tool fix on packages
    fmt         run gofmt on package sources
    generate    generate Go files by processing source
    get         download and install packages and dependencies
    install     compile and install packages and dependencies
    list        list packages
    run         compile and run Go program
    test        test packages
    tool        run specified go tool
    version     print Go version
    vet         run go tool vet on packages

Use "go help [command]" for more information about a command.

Additional help topics:

    c           calling between Go and C
    buildmode   description of build modes
    filetype    file types
    gopath      GOPATH environment variable
    environment environment variables

    testfunc    description of testing functions

Use "go help [topic]" for more information about that topic.

However, I'm currently trying to install hub, and I have successfully clone the repository, but when I execute script/build -o ~/bin/hub, I get this error message:

script/build: line 43: go: command not found

The line contains this content:

local version="$(go version)"
What is causing this error? I tried listing out the current path using echo "$pwd", but it doesn't give any output.

Hi thanks for reporting this. Have you solved this in the meantime? It's very confusing that you're able to run go from your terminal, but when you run script/build, the go command is suddenly unavailable. 😕 This could only be possible if script/build messes up the PATH somehow, which it doesn't, since nothing in that script edits the PATH variable.

[zhengqunkoo]

Hi adl1995, I followed these instructions, and script/build recognizes go 1.8.

However, there are interrupted system calls.

~/hub$ script/build -o ~/bin/hub

~/bin/hub does not exist, and even after mkdir ~/bin/hub, the error persists. Anyone knows how to resolve this?

[mislav]

@zhengqunkoo Yours sounds like a very different problem. If it persists, would you please open a separate issue for it?

@adl1995 Did you ever solve your problem? Are you still unable to build hub on your machine?

[adl1995]

@mislav - Thank you for following up!

Yes, I resolved the go issue. I think my PATH was messed up, I fixed it by re-updating using:

export PATH=$PATH:/usr/local/go/bin

However, I am faced with another problem now. When doing make install prefix=/usr/local, I'm getting this error:

Installing tilt 1.3.3
Using bundler 1.12.5
An error occurred while installing ffi (1.9.3), and Bundler cannot continue.
Make sure that gem install ffi -v '1.9.3' succeeds before bundling.
Could not find ffi-1.9.3 in any of the sources
You need Ruby 1.9 or higher and Bundler to run hub tests
make: * [bin/ronn] Error 1

But, then I checked my Ruby version using ruby -v which came to be:

ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]

Is it possible that I have two versions installed which are conflicting with each other?

[zhengqunkoo]

Hi @mislav, I'm using the Windows Subsystem for Linux (aka Ubuntu 14.04 on Windows). Didn't solve this problem, but found a workaround. Installed linuxbrew and did brew install hub.

[mislav]

@adl1995 Can you try script/bootstrap again to retry installing the necessary dependencies? It's not right that "ffi" gem install should not be found, since I can see that it's available here: https://rubygems.org/gems/ffi/versions/1.9.3

[adl1995]

@mislav I just tried this, but got the same error:

[mislav]

@adl1995 Very strange. Can you try bundle update ffi?

[mislav]

@adl1995 That sounds like you need the necessary Ruby headers on your machine to install gems with native extensions? Typically this is called ruby-dev or libruby in your package manager. Then retry the bundle update ffi command again.

[adl1995]

@mislav So, I installed both ruby-dev and libruby through apt-get, but I'm still getting the same error:

Try checking mkmf.log files as suggested in the output to see what fails. Unless you've compiled software before on this machine, it's possible that you also need to install a package sometimes called build-essentials which installs general-purpose compilers and build tools.

However: the make install step only requires all these Ruby dependenices stuff _just to build the man pages_. Otherwise, Ruby is not required at all. If all you're trying to do is build a hub binary, then you can do make and copy the resulting bin/hub binary somewhere in your PATH.

Although this is not a fix for the specific issue your having why not use the binary? : https://github.com/github/hub/releases.

The Linux binary should work for 14.04 (I've been successful with 16.04). At least it's worth a try for simplicity's sake.

wget https://github.com/github/hub/releases/download/RELEASE/hub-linux-amd64-VERSION.tgz
tar zxvf hub-linux-amd64-VERSION.tgz -C ~/bin # if only needed for current user (in path)
ln -s ~/bin/hub-linux-amd64-VERSION/bin/hub ~/bin/hub

Confirm success:

$ hub version
git version GIT_VERSION
hub version VERSION

If you then want to alias with git and/or include autocompletion - add to .bashrc:

# alias with git
eval "$(hub alias -s)"

# add autocompletion
if [ -f /home/USER/bin/hub-linux-amd64-VERSION/etc/hub.bash_completion ]; then
    . /home/USER/bin/hub-linux-amd64-VERSION/etc//hub.bash_completion
fi

Finally, source .bashrc or start a new terminal session to enable.

@joshmorel Thank you that worked! Closing this issue now.
