go project build failed: lfstackPack redeclared in this block

Question

I am new to Go, when I built my project, it returned the following the error:

/usr/local/go/bin/go run /home/qiuwei/GoWorkSpace/src/LearnGo/SoHi/Hello.go

Show my go env:

export PATH=$PATH:/usr/local/go/bin
export GOPATH=$HOME/GoWorkSpace

Go version: go1.6.3. OS: Ubuntu 14.04

How to fix it?

Answer 1

Remove all the extracted files and extract the 1.6 tar again. If you are still seeing the issue, you may try restarting your Terminal as well.

sudo rm -rf /usr/local/go
tar -C /usr/local -xzf go$VERSION.$OS-$ARCH.tar.gz
