How does Go update third-party packages

Question

Looking how actively golang packages grow and improve I wonder how the problem with package versions is solved   I see that one way is to store third-party packages under a project folder   But what if I install it with go get

User · Accepted Answer

go get will install the package in the first directory listed at GOPATH  an environment variable which might contain a colon separated list of directories   You can use go get -u to update existing packages   You can also use go get -u all to update all packages in your GOPATH  For larger projects  it might be reasonable to create different GOPATHs for each project  so that updating a library in project A wont cause issues in project B   Type go help gopath to find out more about the GOPATH environment variable

Since the question mentioned third-party libraries and not all packages then you probably want to fall back to using wildcards    A use case being  I just want to update all my packages that are obtained from the Github VCS  then you would just say    go get -u github com               being the wildcard      This would go ahead and only update your github packages in the current  GOPATH  Same applies for within a VCS too  say you want to only upgrade all the packages from ogranizaiton A s repo s since as they have released a hotfix you depend on   go get -u github com orgA
