Warning: package-name is trying to unpack in the same destination

[shivam6543]

Hello Team,

In my project, I’m using the following dependencies:

    "monaco-editor": "npm:@codingame/monaco-vscode-editor-api@~7.0.7",
    "monaco-languageclient": "~8.7.0",
    "vscode": "npm:@codingame/monaco-vscode-api@~7.0.7",
    "vscode-languageclient": "~9.0.1",
    "vscode-ws-jsonrpc": "~3.3.2"

but when I run yarn install it shows this warning in the terminal:

warning Pattern ["monaco-editor@npm:@codingame/monaco-vscode-editor-api@~7.0.7"] is trying to unpack in the same destination "/Users/hello/Library/Caches/Yarn/v6/npm-monaco-editor-7.0.11-3jaeh3jhj34j2324fk3b23g-integrity/node_modules/monaco-editor" as pattern ["monaco-editor@npm:@codingame/[email protected]"]. This could result in non-deterministic behavior, skipping.
warning Pattern ["vscode@npm:@codingame/monaco-vscode-api@~7.0.7"] is trying to unpack in the same destination "/Users/hello/Library/Caches/Yarn/v6/npm-vscode-7.0.11-k2n3b1g2k5j6h1v3g5j6h4z8j1o9-integrity/node_modules/vscode" as pattern ["vscode@npm:@codingame/[email protected]"]. This could result in non-deterministic behavior, skipping.

I’m only installing v7.0.7 but some other package is also trying to install v7.0.11. I’m using yarn package manager to install dependencies.

I tried removing ~ from the packages versions but
still somehow it installs two versions. I also tried to run yarn cache clean —all before running yarn install.

Can you please help me how can I install only one version of the dependencies in my project. Thanks!

@kaisalmen On further debugging this issue, I found out that [email protected] has monaco-editor@~7.0.7 and vscode@~7.0.7 as a direct dependency with ~. So, when I try to install mlc@~8.7.0 then it automatically upgrades the monaco-editor and vscode packages to the latest 7.0.x version as monaco-editor and vscode dependency has ~.

can we do something to prevent this issue? Is it ok to get that warning?

[kaisalmen]

@shivam6543 this is done intentionally ~ ensures that the latest patch versions are installed automatically. I don't know if yarn behaves correctly here. Do you already have lock file in place? Try yarn update to ensure all minor versions are updated to the same version.

[shivam6543]

@kaisalmen Yes, I’ve yarn.lock file at the root of my project and I also tried running this command
yarn upgrade monaco-editor monaco-languageclient vscode vscode-languageclient vscode-ws-jsonrpc

And got this output:

Output:
success Saved lockfile.

From the output, it doesn’t seem like it upgraded the monaco-editor and vscode package version.

When I ran the above upgrade command, I got the same warning and after the command completion, it didn’t show any changes in the yarn.lock. Am I missing something?

[kaisalmen]

@shivam6543 is what yarn list helping to reveal where the different versions come from?

[shivam6543]

@kaisalmen here is the output of the yarn list. From the output, it seems like mlc is installing the 7.0.7 but I’ve monaco-editor and vscode as a direct dependency because of that it’s trying to install 7.0.11. Any idea how to install only one version for all the packages?

@shivam6543 is possible that yarn @codingame/monaco-vscode-languages-service-override@~7.0.7 does not interpret this correctly. npm had some issues with this in the past if I remember correctly. Is it possible you try it with npm or pnpm. I need to see if I can reproduce it with yarn. Personally, I would not start a new project with yarn 1. But if that is not possible for whatever reason, we need to see if there is a solution or a workaround.

[shivam6543]

@kaisalmen In my case, it’s not possible to use npm or pnpm. Please let us know if you find any solution or workaround for this issue.

[kaisalmen]

@shivam6543 don't know why I though about it earlier, but you can use yarn resolutions to enforce a specific version to circumvent such problems: https://classic.yarnpkg.com/lang/en/docs/selective-version-resolutions/
