I don't understand this error nor why it is only occurring on x86-windows:

Found the following errors:
Error: While reading versions for port libopusenc from file: C:\a\1\s\port_versions\l-\libopusenc.json
       Version `0.2.1#1` was not found in versions file.
       Run:

           vcpkg x-add-version libopusenc

       to add the new port version.

To attempt to resolve all erros at once, run:

    vcpkg x-add-version --all

Hi @Be-ing

You need to merge master and run the command vcpkg x-add-version libopusenc to solve the error.

[Be-ing]

vcpkg x-add-version libopusenc fixed it but vcpkg x-add-version --all did not.

[Be-ing]

x86-windows still failed. I don't know what's going on.

[NancyLi1013]

It seems that you missed port_versions/baseline.json since this file also contains changes.

[Be-ing]

port_versions/l-/libopusenc.json was changed when I ran vcpkg x-add-version libopusenc and I committed that and force pushed. port_versions/baseline.json was not changed, nor was it changed by vcpkg x-add-version --all

[NancyLi1013]

I run vcpkg x-add-version libopusenc, port_versions/baseline.json is changed. But I have no permission to submit this change.

Please check it again.

vcpkg x-add-version --all is for all ports. In this PR, you just need to run vcpkg x-add-version libopusenc .

[Be-ing]

After I run vcpkg x-add-version libopusenc, git status shows no files changed.

[NancyLi1013]

you can remove this content in port_versions/l-/libopusenc.json, then run vcpkg x-add-version libopusenc.

  "versions": [
    {
      "git-tree": "132909a5cb3c33e038cf9728427910fce455591d",
      "version-string": "0.2.1",
      "port-version": 1
    },

[Be-ing]

That just added the same content back to port_versions/l-/libopusenc.json

[NancyLi1013]

Could you please check port_version/baseline.json and if there are changes in this file?

it should be this in your PR:

"libopusenc": {
     "baseline": "0.2.1",
     "port-version": 1
   },

In vcpkg mater branch, it should be this:

  "libopusenc": {
      "baseline": "0.2.1",
      "port-version": 0
    },

[Be-ing]

I manually edited port_versions/baseline.json and CI is passing now.

Thanks a bunch for the fix and sorry for the PR trouble!

[Be-ing]

I suspect the issue was caused by this package not previously having any port-version specified. I suggest looking into it further to make x-add-version more robust, but I don't really understand what that is for and how it works so I don't know what else to do.
