Problem Description

A few days ago, I upgraded Go to go1.14. When I needed to debug some code, GoLand displayed the following error:

Version of Delve is too old for this version of Go(maximum supported version 1.12, suppress this error with –check-go-version=false)

This issue occurs because Go 1.14 does not install the delve tool by default, while debug requires it.

Solution

Download Delve

Open a terminal and navigate to the $GOPATH\src directory ($GOPATH is the goPath directory configured on your computer; mine, for example, is C:\Jalen\Programming\GoPath\src), then run the following command:

1

go get -u github.com/go-delve/delve/cmd/dlv

This process may take a while because it downloads the Delve package locally and compiles it into an executable file.

If the command succeeds, it will create the \github.com\go-delve\delve\ folder under the src directory and download the delve project into it, as shown below:

At the same time, the compiled dlv.exe file will be generated in the $GOPATH\bin\ directory, as shown below:

Solution for Download Failures

On some computers, running go get -u github.com/go-delve/delve/cmd/dlv may hang with no response in the command line, and the dlv.exe file is not generated. In this case, we can manually download the Delve project locally.

1. Create the $GOPATH\src\github.com\go-delve\ folder.

2. In this folder, run git clone https://github.com/go-delve/delve.git to clone the project code locally.

3. Navigate to $GOPATH\src\github.com\go-delve\delve in the terminal and run the following command:

1

go install github.com/go-delve/delve/cmd/dlv

4. After the command finishes, the dlv.exe executable file will be generated in the $GOPATH\bin directory.

5. Configure GoLand to use this file by clicking Help > Edit Custom Properties…, as shown below.

If you have not configured this in GoLand before, a create dialog box will appear. Click create.

6. Enter dlv.path=$GOPATH\bin\dlv.exe. For example, on my computer, I entered:

1
2

# custom GoLand properties
dlv.path=C:\\Jalen\\Programming\\GoPath\\bin\\dlv.exe

Note that on Windows, you need to use double backslashes in the path: \\. You can also use forward slashes: /.

7. Restart GoLand, and you will be able to use the debugger normally. Problem solved! ^_^
