Gatsby: Error: librsvg-2.so.2: cannot enable executable stack as shared object requires:

[Lc0rE]

Description

After upgrading both gatsby-cli and all the gatsby-* dependencies and plugins in the package.json, I'm facing the following error invoking gatsby-develop:

error UNHANDLED EXCEPTION

Environment

Gatsby version: 1.9.183
Node.js version: 8.9.4
Operating System: Windows 10 on WSL (Ubuntu)

Any ideas on what could cause this unexpected behavior? This only occurs on the WSL substrate on Windows 10. I tested it on macOS and it works fine.

I tried to delete both node_modules, .cache/ and build/ folders but nothing changed.

@Lc0rE This could be an issue with sharp and WSL. It looks like there's some suggested workarounds over at https://github.com/lovell/sharp-libvips/issues/3

[Lc0rE]

Sorry, I forgot to mention that I tried to follow the steps proposed in the sharp issue you linked.

Trying to invoke the command execstack -c node_modules/sharp/vendor/lib/librsvg-2.so.2 gives me a execstack: cannot open "node_modules/sharp/vendor/lib/librsvg-2.so.2": No such file or directory error because it can't find the sharp library installed.

Since, as far as I understand, gatsby-image is relying on the sharp library to work, I'm wondering where to find the sharp module.

There is a sharp folder in node_modules/gatsby-plugin-sharp/sharp but it doesn't contain the librsvg-2.so.2 file.

[Lc0rE]

Ok apparently I solved the issue like this:

• cd node_modules/gatsby-plugin-sharp
• execstack -c node_modules/sharp/vendor/lib/librsvg-2.so.2

At this point, invoking gatsby develop is giving back a Cannot find module sharp. While I don't recall of having installed sharp manually, the following steps are solving the issue:

• back to the root of the project
• npm install --save sharp

Now it's working.. hope it helps!

gatsby-image depends on gatsby-transformer-sharp which depends on gatsby-plugin-sharp which depends on sharp. In case you were curious about the exact genealogy here :-)

@Lc0rE: Thanks a lot! Could this workaround be somehow added to sharp build script?
Or the underlying cause (librsvg-2.so.2) requires a library by its original ELF header?

For me this single command sufficed:
$ execstack -c node_modules/sharp/vendor/lib/librsvg-2.so.2

Current long-term fix for me is this command as postinstall script in package.json of the project using it:
"postinstall": "execstack -c node_modules/sharp/vendor/lib/librsvg-2.so.2"

Edit: Note: With recent sharp and node the workaround above may not be needed anymore and could cause a build error.
