I am getting the same issue on npm 8.3.1 using WSL. What version of npm are you using?
npm error command sh -c npx playwright install
message appears on the console, so it looks like there is an error installing playwright. I noticed this problem when running "npm -g update".
I also confirmed that the error can be avoided by removing the global option. We need to avoid global installations as a workaround for the time being.
In my case, my OS is Ubuntu MATE 25.04, but I found out that playwright only supports up to 24.10 on Ubuntu-based OS, which is why errors occur when updating or installing. This issue may not be resolved until Microsoft supports playwright up to 25.04.
I'll explain in more detail. Playwright depends on libicu74. However, the libicu in Ubuntu 25.04 is libicu76. As a result, the dependency is not met, which is likely why an error occurs in playwright.
This worked for me:
npm install -g @playwright/[email protected] @mermaid-js/mermaid-cli
Seems that playwright version 1.53 is the issue.
It looks like this issue no longer happens now. I was able to install on wsl with no changes to the command necessary
Reproduction environment:
OS : Ubuntu MATE 25.04 Plucky Puffin
NodeJS : v20.18.1
npm : 9.2.0
Need more information?
Looks like we have to read the URL below. https://www.npmjs.com/package/@mermaid-js/mermaid-cli/v/8.9.1#install-globally
The issue was with cytoscape and has been fixed now: https://github.com/cytoscape/cytoscape.js/issues/3368
However, I don't think this dependency has been updated since.
One workaround is to add an explicit dependency to package.json:
"cytoscape": "3.31.4",
Then as soon as it is added to the package-lock.json file it can be removed from the package.json.
