node-zopfli not found eventhough it is installed

[ykravv]

Hmm, I'm trying to run it inside fresh docker container and getting these error. Anyway, thank you
It's strange, but locally with NODE_ENV=production everything is working. So something is missing in docker container

I managed to fix it via npm rebuild

[Eightyplus]

You tell me, you created the loose dependency.

[Eightyplus]

I't works when install [email protected], please use specific version!

[michael-ciniawsky]

@Eightyplus Curious, why the version must be specific ? 😛

[michael-ciniawsky]

kk I see now 😛 , I'm not the maintainer here, I will check why it is there in the first place and if it can be safetly removed, mom.

[Eightyplus]

We are struggeling with loose dependencies and migrating toward yarn to avoid this problem. But now and then it breaks because we haven't locked down all dependencies :)

[michael-ciniawsky]

Setting it and the current range maybe also wrong :)

[Eightyplus]

I'm still trying to locate the exact problem, printing console.log(err) before the error is thrown I get the following. It could indicate problems with another dependency, I'll keep you updated.

What version of node/npm is required?

[michael-ciniawsky]

What version of node/npm is required?

@Eightyplus webpack 1 + plugin should be fine with node>= 0.12.x && npm >=2.x, webpack 2 requires node >= 4

/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by /usr/src/app/node_modules/node-zopfli/lib/binding/node-v51-linux-x64/zopfli.node)

This is a node native modules (C/C++) issue in node-zopfli the glibc on your system may mismatch with the one required by node-zopfli. Why and if this an issue because of the node version in use etc., I'm no real help here, since C/C++ isn't my daily bread :D

[Eightyplus]

Hi, it turn out it is a build vs. runtime environment issue. Sorry about that.

[ykravv]

@Eightyplus Hey, I've got the same issue.

Error: Cannot find module '/usr/src/app/node_modules/node-zopfli/lib/binding/node-v51-linux-x64/zopfli.node'
    at Function.Module._resolveFilename (module.js:470:15)
    at Function.Module._load (module.js:418:25)

How did you solve this? Thanks

[Eightyplus]

Well, the build/runtime environment was different, so the packages has to be rebuild as suggested
rm -rf node_modules && npm install

[Eightyplus]

Maybe your production env is different from the other env's. I would check my webpack.config.js then.

[joshwiens]

@Eightyplus - For reference, zopfli is being split out into it's own lib in the upcoming Major version of compression-webpack-plugin.

[Eightyplus]

@d3viant0ne thanks for letting me know!

[joshwiens]

FYI the [email protected] release officially removes the loose dependency. More information can be found in the changelog.md
