Could not find a copy of {pkg.name} to link in {location}

Do you want to request a feature or report a bug?

Report a bug.

What is the current behavior?

When doing yarn install, I get an linking error at the very end when yarn attempts to link packages under the hood, causing the overall install to fail.

If the current behavior is a bug, please provide the steps to reproduce.

This is consistently reproducible when running a simple yarn install. This was also present in version 1.9.2, but I waited to see if 1.9.4 would fix it, as it was a fast-follow.

Here is the (sanitized) error in trace in my yarn-error.log =>

Invariant Violation: could not find a copy of uuid to link in /home/tquetano/git/{repository}/node_modules/{package}/node_modules
      at invariant (/usr/lib/node_modules/yarn/lib/cli.js:1745:15)

      at process._tickCallback (internal/process/next_tick.js:188:7)

What is the expected behavior?

To install properly!

Please mention your node.js, yarn and operating system version.

Node => 8.11.4
Yarn => 1.9.4
OS => Manjaro Linux (Arch-based)

If there is more specific information I can provide to help, please let me know.

  1. I’m seeing this also. I believe it has to do with peer-dependencies. In my case, I’m trying to install eslint-config-standard-preact which has a peer dependency of eslint >= 3.0.0. When I have eslint-config-standard-preact installed and run yarn add -D eslint, I receive errors similar to those above even though the version it is installing (5.7.0) matches that criteria. As pointed out on zouhir/eslint-config-standard-preact#11, you can install a specific version (even if it’s effectively the same) and it’ll work (ex. yarn add -D eslint@5.7.0).

  2. I found a stupid workaround, just specify version like this yarn add uuid@3.3.2 I did it following the yarn clean cache uuid but it could be enough by itself
