Trying legacy get get...go: go.mod file not found in current directory or any parent directory.
'go get' is no longer supported outside a module.
To build and install a command, use 'go install' with a version,
like 'go install example.com/cmd@latest'
For more information, see https://golang.org/doc/go-get-install-deprecation
or run 'go help get' or 'go help install'.
FAILED
The installation failed; please see above for the actual error. In order to get more information, please re-run the command, adding the --verbose flag. If you think this is a bug and you raise an issue, you MUST include the *full verbose* output.
For example, run:/usr/bin/python3 /home/seb/.vim/pack/YouCompleteMe/start/YouCompleteMe/third_party/ycmd/build.py --all --verbose
I expected the install script to also work with go 1.25.1
It looks like this issue is due to a dependency being incompatible with go 1.25 https://github.com/golang/go/issues/74462
In my test I could make the install step work, by increasing the gopls version to v0.20.0 in https://github.com/ycm-core/ycmd/blob/master/build.py#L967
I would be happy to provide a pull request for this.
