xcaddy: command not found when building caddy

[marcoippolito]

Following these indications: https://caddyserver.com/docs/install#build-from-source
in Ubuntu 18.04.4 Desktop I installed xcaddy

go get -u github.com/caddyserver/xcaddy/cmd/xcaddy
go: downloading github.com/caddyserver/xcaddy v0.1.2
go: found github.com/caddyserver/xcaddy/cmd/xcaddy in github.com/caddyserver/xcaddy v0.1.2
go: downloading github.com/Masterminds/semver v1.4.2
go: downloading github.com/Masterminds/semver/v3 v3.1.0
go: github.com/Masterminds/semver/v3 upgrade => v3.1.0

And tried to build caddy:

(base) marco@pc01:~/golangMatters/caddy/cmd/caddy$ xcaddy build v2.0.0-rc.3 \
> --with github.com/caddyserver/nginx-adapter
xcaddy: command not found

How to solve the problem?

Duplicate of #6 and #5 -- as usual with any commands, just make sure it is in your PATH and that it is executable.

(base) marco@pc01:~$ echo $PATH
/home/marco/anaconda3/bin:/home/marco/anaconda3/condabin:/home/marco/.pyenv/plugins
/pyenv-virtualenv/shims:/home/marco/.pyenv/shims:/home/marco/.pyenv/bin:/home/marco

/node/12.9.1_64bit/bin:/home/marco/emsdk-master/upstream/emscripten

/home/marco/go/bin seems to be in the path

And it is executable:

(base) marco@pc01:~/go/bin$ ls -lah

-rwxr-xr-x 1 marco marco 4,6M apr 24 18:12 xcaddy


(base) marco@pc01:~/go/bin$ xcaddy
2020/04/24 19:02:57 [ERROR] exec: "go": executable file not found in $PATH

nano .bashrc :

export GOROOT=/usr/lib/go
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

[mholt]

That's a different error now: exec: "go": executable file not found in $PATH

Make sure that the go command is in your PATH too.

Solved. Thank you

In case you end up here trying to install xcaddy:

Make sure you have something like this in your ~/.bashrc:

export GOROOT=/usr/lib/go
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

And install caddy with:

go install github.com/caddyserver/xcaddy/cmd/xcaddy@latest

The docs say to use go get -u github.com/caddyserver/xcaddy/cmd/xcaddy, but that is no longer correct.

Which docs are you speaking of?? It's been saying go install for the past one and half years: 8365548
