I'm having trouble setting up Go App engine on osX. Should the google-cloud-sdk path be in GOROOT or GOPATH?
I put the google-cloud-sdk in /usr/local
It looks like there is source code in: goroot/
/usr/local/google-cloud-sdk/platform/google_appengine/goroot/
go env
GOPATH="/usr/local/google-cloud-sdk/platform/google_appengine/goroot"
GORACE=""
GOROOT="/usr/local/go"
GOTOOLDIR="/usr/local/go/pkg/tool/darwin_amd64"
$ go get
package google.golang.org/appengine: cannot download, /usr/local/google-cloud-sdk/platform/google_appengine/goroot is a GOROOT, not a GOPATH. For more details see: 'go help gopath'
package google.golang.org/appengine/datastore: cannot download, /usr/local/google-cloud-sdk/platform/google_appengine/goroot is a GOROOT, not a GOPATH. For more details see: 'go help gopath'
When I attempted to change the PATH to include /src:
GOPATH="/usr/local/google-cloud-sdk/platform/google_appengine/goroot/src"
$ go get
package google.golang.org/appengine: mkdir /usr/local/google-cloud-sdk/platform/google_appengine/goroot/src/src: permission denied
package google.golang.org/appengine/datastore: cannot find package "google.golang.org/appengine/datastore" in any of:
/usr/local/go/src/google.golang.org/appengine/datastore (from $GOROOT)
/usr/local/google-cloud-sdk/platform/google_appengine/goroot/src/src/google.golang.org/appengine/datastore (from $GOPATH)
I appended the path to google-cloud-sdk to GOROOT:
export GOROOT="/usr/local/go/:/usr/local/google-cloud-sdk/platform/google_appengine/goroot"
GO doesn't seem to like multiple paths in GOROOT:
$ go get
go: cannot find GOROOT directory: /usr/local/go/:/usr/local/google-cloud-sdk/platform/google_appengine/goroot
I did run the ./install.sh script after I copied the source to /usr/local
The additional PATH's added did not fix the errors I was having.
I saw this answer: Test cases for go and appengine
But it's from 5 years ago and it seems clunky/hacky. It would seem in 5 years there would be a more elegant solution that copying individual directories and creating symlinks.
EDIT **********************mv /usr/local/google-cloud-sdk/ ~/go/
then deleted GOPATH and GOROOT from .bash_profile
I then ran ./install.sh
I attempted to run 'go get':
$ go get
go install: no install location for directory /Users/Bryan/work/gocode/skincarereview outside GOPATH
Since that failed, I added the path to the working directory of code AND appended the path to google-cloud-sdk to PATH:
export GOPATH = "/Users/Bryan/work/gocode/skincarereview"
export PATH=$HOME/google-cloud-sdk:$PATH
go get
get failed with the same message:
$ go get
go install: no install location for directory /Users/Bryan/work/gocode/skincarereview outside GOPATH
For more details see: 'go help gopath'
It goes in neither $GOROOT or $GOPATH. Just unpack it to your $HOME directory and run the installer. If necessary, add it to your $PATH by adding this line to your .bash_profile
.
export PATH=$HOME/google-cloud-sdk:$PATH
Make sure you grab the golang SDK as well with gcloud components install app-engine-go
https://cloud.google.com/appengine/docs/standard/go/download
DO NOT change your path to include the src dir in google-cloud-sdk/platform/google_appengine/goroot/src
. That will break things. You leave your $GOPATH to be your normal installation. Using the App Engine SDK for Go automatically uses the sources in that dir without any manipulation.
Also, you should NEVER MANUALLY change $GOROOT unless you plan on compiling a new Go version from source (as in a new version of the language). It will automatically set the proper $GOROOT for you. https://dave.cheney.net/2013/06/14/you-dont-need-to-set-goroot-really
If your install is messed up beyond reason (happened to me once), just remove the cloud SDK and any references to it in your $PATH. Also completely uninstall the regular Go installation. Then start from scratch. Install Go, unpack google-cloud-sdk, run installer (add to $PATH if needed), gcloud components install app-engine-go
. Voila.
When developing for App Engine, your go sources go into your REGULAR $GOPATH. They DO NOT go in google-cloud-sdk/...
anywhere. To run the dev_appserver locally, run dev_appserver.py [path-to-source]
where the given path contains your code and the app.yaml. I usually cd
in to my project path (e.g. cd $HOME/go/src/myproject
) and run with dev_appserver.py ./
. https://cloud.google.com/appengine/docs/standard/go/tools/using-local-server
Deployment is covered here. https://cloud.google.com/appengine/docs/standard/go/tools/uploadinganapp
EDIT: Folder structure.
$GOPATH = $HOME/go
Location for google-cloud-sdk folder
