I tried to install Revel Framework. I followed all the steps as given in the documentation but whenever I tried to run the Revel command it throws panic error. Following are the steps which I am performing Enviormental path:

export GOROOT=/usr/local/go
export GOPATH=/Users/<username>/Desktop/gocode
export PATH="/Users/<username>/gocode/bin:$PATH"

To install Revel

go get github.com/revel/revel
go get github.com/revel/cmd/revel
export PATH="$PATH:$GOPATH/bin"

when I run revel version it shows:

panic: runtime error: slice bounds out of range

Solution

  • Try re-install the revel

    Here is how I have tried and it works for me.

    1. Set the go path ($GOPATH):
    export GOPATH=/var/projects/go
    1. Install revel & cmd:
      go get github.com/revel/revel
  go get github.com/revel/cmd/revel
    1. Link revel cmd to bin directory. So the command could be executable.
    export PATH="$PATH:$GOPATH/bin
    1. Check revel is working or not. Just type revel in command line

    Output would be like this

        Usage:
      revel [OPTIONS] <command>

    Application Options:
      -v, --debug              If set the logger is set to verbose
          --historic-run-mode  If set the runmode is passed a string not json
      -X, --build-flags=       These flags will be used when building the application. May be specified multiple times, only applicable for Build, Run,
                               Package, Test commands

    Available commands:
      build
      clean
      new
      package
      run
      test
      version
    1. Check revel version:
    revel version

    Output

        Revel executing: displays the Revel Framework and Go version
    Revel Framework :   0.21.0  (0.21.0 remote master branch)
    Revel Cmd   :   0.21.1  (0.21.1 remote master branch)
    Revel Modules   :   0.21.0  (0.21.0 remote master branch)
    1. Now, You can create first project using command 
    revel new myapp

    Output 

        Revel executing: create a skeleton Revel application
    Your application has been created in:
       /var/projects/go/src/myapp

    You can run it with:
