OS: Ubuntu 12.04
Go version reporting: 1.1.1
Action:
I have configured the .profile to contain the following lines:
export GOPATH="$HOME/workspace"
export PATH=$PATH:$GOPATH/bin
I have ensured that they are set in the go configuration by running "go env". However when I try to run the command, the screen reports as shown in the image below:
Possible constraining issues:
1) The box originally had Go v1.0 on it and I upgraded it to go version1.1.1, not sure that should mean anything...but if there is some twin configuration madness at work that may explain the fact it's not working despite the path being set.
2) I had the export commands in the .profile file but I see some threads indicate to put it in .bashrc, trying in either still gives the same problem.
Do I need to uninstall go 1.0 ? I just assumed version 1.1.1 would over ride it but that could be wrong. Ideally I wanted to uninstall go entirely and then install version 1.1.2 but I couldn't find anything at golang.org on uninstalling assuming that does solve the problem.
Thanks in advance for any assistance.
As the commenter above stated, you should not use sudo with go get. When you do, you have the root user's environment (which doesn't have your GOPATH) and any files or directories it creates won't be editable by your user. In the past, the go get command would not warn about not having a $GOPATH and so it was easier to get tripped up by this.
To fix your permissions, run the following command to change ownership back to your user:
sudo chown -R "$USER:" "$GOPATH"
You should only ever need to run a plain go get because you can (and should) set your $GOPATH to be a directory you can control. Be sure to read the How To Write Go Code and in particular its discusson on GOPATH.

After installing golang according to the instructions on the golang website, I set the path as it said to by using export PATH=$PATH:/usr/local/go/bin and whenever I use the command $HOME/go it says bash: /home/ken/go: No such file or directory
I can verify go is installed and I even reset my computer to make sure the changes took place. Does anybody know what I can do to resolve this issue? Am I missing something?
As per the instructions on the Go installation page, you do need to manually create the go folder:
cd $HOME
mkdir go
cd go
Then create your first go program: https://gobyexample.com/hello-world
And run with go run hello-world.go. Should be good ;)
Im new to go and I have been unable to find any thing online for my issue.
I have downloaded this code https://github.com/hashicorp/http-echo and I would like to set it up so I can run this command.
$ http-echo -listen=:8080 -text="hello world"
I have been getting quite a few different path issues.
Currently I have the code sitting in this directory.
/Users/jon/go/src/github.com/hashicorp
When I try and install it I get this error
$ go install http-echo
can't load package: /usr/local/go/src/http-echo/handlers.go:9:2: non-standard import "github.com/hashicorp/http-echo/version" in standard package "http-echo"
Where should I keep go projects on an OSX computer, and how do I get this to install or compile?
The code currently seems to be in /usr/local/go/src/http-echo. Packages should always reside in the directory $GOPATH/src/package-name, e.g.: $GOPATH/src/github.com/hashicorp/http-echo. (unless you're using go modules).
It should work if you move the source to the correct path (/Users/jon/go/src/github.com/hashicorp/http-echo). Then execute:
go install github.com/hashicorp/http-echo
Even easier would be to use go get to download the package in the first place. Simply run the following command from any directory:
go get github.com/hashicorp/http-echo
And http-echo is automagically installed.
If you still get an error after this, make sure $GOPATH/bin is in your $PATH.
I am getting this error when I tried to run an example helloworld code I got onlie.
compile: version "go1.9" does not match go tool version "go1.9.1"
My computer has go1.9.1. What does the error mean and how can I fix this?
If you are installing using OSX homebrew you may need to set the $GOROOT in your .bashrc, .zshrc, etc:
export GOROOT=/usr/local/opt/go/libexec
I had the same error this morning when I updated from 1.9 -> 1.9.1 though according to several post the $GOROOT shouldn't have to be set and I had not set it until today. This may be a bug?
Edit: not a bug, for more details see answer below.
This is a mismatch between the GOROOT environment variable and the default path to your go command. One or the other needs to be changed; the one that needs to be changed depends on the specific setup on your computer. You could determine this by updating your Go to the latest version using your preferred method, running either which go (on Linux/macOS/BSD) or where go (on Windows), and then checking which of the files listed has the newer timestamp.
Linux/macOS/BSD
To change the GOROOT to match the default path of your go command, run type go and strip off the /bin/go part at the end to yield the directory path containing your Go installation. Then, add it to your .bashrc or other appropriate init file like this:
export GOROOT=/path/to/go-installation
To instead change the go command path to match your GOROOT, add this to the bottom of your init file:
export PATH="${GOROOT}/bin:${PATH}"
Windows
To change the GOROOT to match the default path of your go command, run where go take the first line of output, and strip off the \bin\go.exe part at the end. Then, go to "Edit the system environment variables" in Settings, click "Environment Variables...", find the "GOROOT" variable and edit to read the path you created earlier.
To instead change the go command path to match your GOROOT, first save the output of echo %GOROOT%\bin. Then, go to "Edit the system environment variables" in Settings, click "Environment Variables...", and find the
find the "Path" row in the bottom pane, click New, put in the path you created earlier, and finally click Move Up until it's at the top.
All
You'll need to open up a new command prompt to see the effects.
in case you are using mac with homebrew, just run:
brew cleanup
to clean all the legacy package, this fixed my problem.
In mac OS , if you downloaded and installed go package without brew, running brew update commands will cause this problem to occur
for fix this problem you can do :
brew uninstall --ignore-dependencies go
uninstalling go from brew will fix problem
This error happens when you forgot to delete previous golang install ... just delete its directory ... so identify go install location ... on linux issue
type go
typical output is
go is hashed (/usr/local/go/bin/go)
so just remove its grandparent directory ( go install dir not just the go binary )
sudo rm -rf /usr/local/go # NOTE this is not /usr/local/go/bin/go
now just install go and you'll be fine
For M1 Mac, the following steps helped me!
Check for which go from VSCode Terminal and check from system terminal.
from vscode terminal
user#mac % which go
/usr/local/go/bin/go
from my mac terminal
user#mac % which go
/opt/homebrew/bin/go
Whichever corresponds to the GOROOT shown go env, keep it and delete the other one
user#mac % go env GOROOT
/usr/local/go
in this case
rm -rf /opt/homebrew/bin/go
close and reload the vscode and terminal
For Windows delete the GOROOT System variables in the Enviroment Variables and restart the PC.
if you use VsCode, you just add this in setting.json.
"go.goroot": "/usr/local/Cellar/go/1.x.x/libexec",
For me, it's caused by GOROOT env, using gotip before, change to brew version.
# curret go env
cat "$(go env GOENV)"
# make sure this is correct
go env GOROOT
# unset GOROOT if setted before
go env -u GOROOT
you may also want to set a proper GOROOT to match the go version.
In my case, I had a scripts that look like this:
[[ -s "$HOME/.gvm/scripts/gvm" ]] && source "$HOME/.gvm/scripts/gvm"
Hanging around in my .bashrc/.zshrc file from a previous installation of go / trying to use gvm.
Removing this and restarting terminal solved it for me.
I had the same issue when I used getgo to update my Go version from 1.19 to 1.20. In my case, getgo created a .bash_profile and set its own export path w/c is not consistent with what's in my .bashrc.
#my .bash_profile;
export PATH=$PATH:/home/user/.go/bin
export PATH=$PATH:/home/user/go/bin
#my .bashrc;
export GOROOT=/usr/local/go/
export GOPATH=$HOME/go
export PATH=$PATH:$/home/user/go/bin:$GOROOT/bin:$PATH
SOLUTION:
I just replaced my export PATH in bashrc w/
export PATH=$PATH:$/home/user/.go/bin:$GOROOT/bin:$PATH
<Note the '.go' change w/c is now consistent to what's in my .bash_profile>.
So whether source is ~/.bashrc or ~/.bash_profile, it will always point to the same path for Go. Hope this helps. I'm also new to Go and Ubuntu. I know how painful it is to get these variables right on your own.
Took a simple approach(Linux), I had different versions of Go installed in my system.
$ whereis go
helped me to find the available go runnables, removed all, installed a fresh one and ensured to create a link for this new Go runnable in one of the $PATH folder to ensure below gives the correct version of what installed now.
$ go version
I have a weird issue with golang. I run the command (like everytime):
go run main.go
Then I made some change into my code and then I run again:
go run main.go
But the executed code is the old version of the code. So I tried some stuff:
Reboot the computer
Delete all the temporary binaries into temp folder
Reinstall go
Delete and put back my code
Remove some file
But it is still running my old version of the code. I didn't find solution about this issue, and the few post about it doesn't give a solution (here and here).
About my configuration it is the following:
Raspberry pi running Raspbian (updated)
Go version 1.8.1
I hope you can help me !
Thank in advance!
Best regards,
Okay!
The problem come from the imports. In the code some imports was calling old version of the code.
I think your GOPATH is pointing to a wrong folder. Please, run go env to make sure that it is pointing to the right directory. If not set it to location where go files are. Please, take into account that go run usually does not need a file specification and if you do you have to list defacto all files of your app that main.go depends upon.
Have a look ``here
If I had a compiled Golang program that I wanted to install such that I could run it with a bash command from anywhere on my computer, how would I do that? For example, in nodejs
npm install -g express
Installs express such that I can run the command
express myapp
and express will generate a file directory for a node application called "myapp" in whatever my current directory is. Is there an equivalent command for go? I believe now with the "go install" command you have to be in the directory that contains the executable in order to run it
Thanks in advance!
Update: If you're using Go 1.16, this answer still works, but go install has changed and is now the recommended method for installing executable packages. See Karim's answer for an explanation: https://stackoverflow.com/a/68559728/10490740
Using Go >= 1.11, if your current directory is within a module-based project, or you've set GO111MODULE=on in your environment, go get will not install packages "globally". It will add them to your project's go.mod file instead.
As of Go 1.11.1, setting GO111MODULE=off works to circumvent this behavior:
GO111MODULE=off go get github.com/usr/repo
Basically, by disabling the module feature for this single command, it will install to GOPATH as expected.
Projects not using modules can still go get normally to install binaries to $GOPATH/bin.
There's a lengthy conversation and multiple issues logged about this change in behavior branching from here: golang/go - cmd/go: go get should not add a dependency to go.mod #27643.
Starting with Go >= 1.16 the recommended way to install an executable is to use
go install package#version
For example, go install github.com/fatih/gomodifytags#latest.
Executables (main packages) are installed to the directory named by the GOBIN environment variable, which defaults to $GOPATH/bin or $HOME/go/bin if the GOPATH environment variable is not set. You need to add this directory to your PATH variable to run executables globally. In my case, I've added this line to my ~/.zshrc file. (if you are using bash, add it to the ~/.bash_profile file):
export PATH="$HOME/go/bin:$PATH"
Go team published a blog post about this change, here's the explanation quote:
We used to recommend go get -u program to install an executable, but this use caused too much confusion with the meaning of go get for adding or changing module version requirements in go.mod.
Refer to go install documentation for more details
As far as I know, there is no direct equivalent to npm install -g. The closest equivalent would not be go install, but go get. From the help page (go help get):
usage: go get [-d] [-f] [-fix] [-insecure] [-t] [-u] [build flags] [packages]
Get downloads and installs the packages named by the import paths,
along with their dependencies.
By default, go get installs binaries to $GOPATH/bin, so the easiest way to make those binaries callable from everywhere is to add that directory to your $PATH.
For this, put the following line into your .bashrc (or .zshrc, depending on which shell you're using):
export PATH="$PATH:$GOPATH/bin"
Alternatively, you could also copy or link the executables to /usr/local/bin:
ln -s $GOPATH/bin/some-binary /usr/local/bin/some-binary
Short solution for Linux users:
Use the go get command as usual
Add the following lines to .bashrc:
# This is the default GOPATH, you should confirm with the 'go env' command
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
Restart terminal or source it. Installed binaries will be available globally.
For Go v1.8+
go install package_name#latest
Caveat: this answer is outdated following the 2020 deprecation of go get. The solution presented here won't work with newer Go runtime installs.
The closest analogue of this in Go would be go get. By default, it will fetch a Go package from a supplied repository URL, and requires a $GOPATH variable to be set in your shell so that Go knows where to store the packages (and subsequently where to find them when compiling code depending on go get-ted packages).
Example syntax:
$ go get github.com/user/repo
The behaviour supplied by npm's -g flag is default, and packages installed using go get are normally available globally.
See go get --help for more information about the command.
As mentioned by #helmbert, adding your $GOPATH to your $PATH is useful if you're installing standalone packages.
if you are using zsh :
first: install your package using :
go install package#version
then , you edit your .zshrc file
nano ~/.zshrc
Add this line to the end of .zshrc file :
export PATH="$HOME/go/bin:$PATH"
last but not least :
source ~/.zshrc
then open a new terminal and execute your command :)
TL;DR at the bottom. I'm going to walk you through how I came to this conclusion, and why the more obvious solutions don't work.
Upon seeing this question, I thought "If I could set root's GOPATH=/usr, it would install things in /usr/bin/ and /usr/src!"
So I tried the obvious thing:
Add GOPATH=/usr to root's .bashrc.
And it worked!
Sort of.
Not really.
Turns out, sudo doesn't execute root's .bashrc. For "security" or something like that.
Do env_set or something in /etc/sudoers
Turns out, /etc/sudoers can only remove environment variables. There's no env_set directive.
(As far as I can find)
Dig through man sudoers.
Where does sudo get it's default set of environment variables from?
Well, the first one in the list is /etc/environment, so that's the one I used.
sudo echo "GOPATH=/usr" >> /etc/environment
sudo go get <repo>
Binaries will be put in /usr/bin, and sources will be put in /usr/src.
Running go as non-root will use GOPATH the "normal" way.
If you don't have go installed, you may use the gobinaries. it builds an on-demand binary of the project from github repo.
The command to install the go package would be:
curl -sf https://gobinaries.com/rakyll/hey | sh
