playwright-fedora-patch

In-place patches for Playwright and Patchright to stop crashing on Fedora/RHEL with apt-get: command not found. Greasy fast-food tier code, but it works. This project contains modified files from Playwright and Patchright, both licensed under Apache-2.0. Modified portions are noted in each file.

Problem

When running crawl4ai-setup, we're told to run two installation commands, both playwright install --with-deps and patchright install --with-deps fail on the Fedora system with:

sh: line 1: apt-get: command not found

This is because both packages hardcode apt-get for installing browser dependencies, but Fedora uses dnf as its package manager.

Files Modified

For Playwright:

1. hostPlatform.js

   • Location: ~/.local/lib/python3.14/site-packages/playwright/driver/package/lib/server/utils/hostPlatform.js
   • Added detection for Fedora/RHEL/CentOS/Rocky/AlmaLinux distributions
   • Maps these distributions to Ubuntu equivalents for dependency compatibility

2. dependencies.js

   • Location: ~/.local/lib/python3.14/site-packages/playwright/driver/package/lib/server/registry/dependencies.js
   • Added commandExists() function to detect available package managers
   • Modified installDependenciesLinux() to detect package manager and skip automatic installation on Fedora
   • Modified validateDependenciesLinux() to show appropriate package manager instructions

For Patchright:

1. hostPlatform.js

   • Location: ~/.local/lib/python3.14/site-packages/patchright/driver/package/lib/server/utils/hostPlatform.js
   • Same changes as Playwright version

2. dependencies.js

   • Location: ~/.local/lib/python3.14/site-packages/patchright/driver/package/lib/server/registry/dependencies.js
   • Same changes as Playwright version

Implementation Details

hostPlatform.js changes:

• Fedora < 32 → ubuntu20.04
• Fedora 32-35 → ubuntu22.04
• Fedora 36+ → ubuntu24.04
• RHEL/CentOS 8 → ubuntu20.04
• RHEL/CentOS 9+ → ubuntu22.04/ubuntu24.04

dependencies.js changes:

1. Detect available package manager (dnf vs apt-get)
2. For Fedora/RHEL systems:
   • Show message listing required packages
   • Skip automatic installation (since Ubuntu package names don't work with dnf)
3. For Debian/Ubuntu: Use apt-get as before
4. Error messages show appropriate install commands based on detected system

Testing Results

Before Fix (Fedora)

$ playwright install --with-deps
sh: line 1: apt-get: command not found

After Fix

$ python3 -m playwright install --with-deps
BEWARE: your OS is not officially supported by Playwright; installing dependencies for ubuntu24.04-x64 as a fallback.
Installing dependencies...

=== Fedora/RHEL detected ===
The following packages need to be installed for browser support:

  dnf install -y libasound2t64 libatk-bridge2.0-0t64 ...

Note: Ubuntu package names may not match Fedora packages exactly.
You may need to install equivalent Fedora packages manually.

Skipping automatic installation on Fedora/RHEL.
Please install the required packages manually or use: sudo dnf install <package>

[Browser installation proceeds...]

Same behavior for patchright install --with-deps.

Packages Needed

dnf install -y alsa-lib libxml2 libxslt libgbm nss at-spi2-core
