cannot download, $GOPATH not set

Question

I want to install json2csv using go get github.com/jehiah/json2csv but I receive this error:

package github.com/jehiah/json2csv: cannot download         


        

Answer 1

I had to run an application as root (to open a webserver on port 80), this produced the error for me, because the sudo user has a different environment than the normal user, hence GOPATH was not set.

If someone else is having this problem, add -E to the command, this will preserve the user environment.

sudo -E go run main.go
