undefined: strings.CutPrefix

When I executed the install command an error was returned, but my go version was greater than the required 1.18.

• Installation command

  go install github.com/cloudflare/cfssl/cmd/...@latest

• Error message

  # github.com/prometheus/common/model
  go/pkg/mod/github.com/prometheus/common@v0.48.0/model/metric.go:363:33: undefined: strings.CutPrefix
  note: module requires Go 1.20

The problem when i try to build an image of my app to extract some metric and this happend in build binary step

So i think in your Dockerfile you need to change to golang image version:

and you may need to change your system go version to >= 1.20

by doing:
Go to this link: https://go.dev/dl/
scroll down you will see:

click on that, scroll down to 1.20

• cd Downloads
• sudo tar -C /usr/local -xzf go1.20.linux-amd64.tar.gz
• vim .zshrc
  -and add this line to .zshrc: - export PATH=$PATH:/usr/local/go/bin
  
• source .zshrc
• go version
  ! After that you may need to restart vscode or computer so the vs can re detect the new go version
  

and then i can build the image

you may dont need to change the go system version, only need to change 1 line in Dockerfile to 1.20
