What did you do?

Set environment variables such that the module cache directory can't be created as a directory. In this example below, I've explicitly set GOMODCACHE to a path I don't have access to.

export GOMODCACHE=/does/not/exist
go install golang.org/x/tools/gopls@latest

This came up in this golang-nuts thread. In that example, neither GOPATH nor GOMODCACHE was set, so GOMODCACHE defaulted to $HOME/go/pkg/mod, but $HOME/go is not a directory.

What did you expect to see?

An error message that explains what the problem is and how to fix it, printed once.

What did you see instead?

An unhelpful message, printed multiple times.

$ go install golang.org/x/tools/gopls@latest
go: writing stat cache: mkdir /does: read-only file system
go: writing stat cache: mkdir /does: read-only file system
go: writing go.mod cache: mkdir /does: read-only file system

8 packages failed to install on vscode so i found a solution which is add these lines to your bash_profile, .bash_profile, .zshrc ,.zprofile:

export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin

after that only 2 packages failed after this so i just typed in go get -u github.com/ramya-rao-a/go-outline

and it solved the problem
