Sharp: CentOS 7: Node 10.12.0 requiring zlib 1.2.9

[sorvani]

Have a look at this thread.

https://github.com/barisusakli/nodebb-plugin-imgur/issues/35

I had to revert to node 10.8.0 in order for this component not to cause a problem.

I did not try the versions in between.

I'm having the same issue on 6.14.3, also on CentOS 7. Same ZLIB 1.2.9 requirement, but the OS only provides 1.2.7. Was working till a recent app update.

Hello, the Error: /lib64/libz.so.1: version ZLIB_1.2.9' not found message is caused by something other than sharp depending on an older system-level zlib shared library before require('sharp') is used.

Known causes of this are:

• When using Electron on Linux - see #892
• When node-canvas is a (transient) dependency - see #843
• When Node has been compiled using the --with-system-zlib flag - see #1405

If the only thing that has changed is the version of Node then the latter could be part of the reason. Perhaps the way in which Node is packaged for Centos 7 has recently changed?

If you're able to narrow down the specific version of Node when things start to break that will be very helpful.

In my case, Node was not updated.

@sorvani @scottalanmiller Were either of you able to make any progress with this?

[sorvani]

I changed versions of node to get around it. I will look at updates in a bit and see what it does now.

[scottalanmiller]

Same here, went to a lower version of NodeJS to avoid the issue.

[lovell]

Thanks for the updates. How is Node installed on these machines? From source or a prebuilt package from a repo? If from a repo, with what config?

I suspect a --with-system-zlib or --shared-zlib build flag was added somewhere between Node 10.8.0 and 10.12.0 to whatever is building it. If you're able to determine the specific version of Node at which it stopped working, that would be very helpful.

I installed node with nvm, and nvm was installed from here: https://github.com/creationix/nvm

[sorvani]

This afternoon, I went through and installed node versions v10.8.0 through v10.13.0.

nvm install v10.9.0
..
nvm install v10.13.0

I then tried each one with this process.

nvm use v10.8.0
npm rebuild
./nodebb stop
./nodebb build
./nodebb start

Then I tried to paste in an image to a post. Now it works for every single version.

The only difference in my system related to node, is I updated npm after seeing this alert.

I have no idea why everything seems to now work normally with all versions.

[lovell]

Thank you for the update. Perhaps there was something temporarily wrong with one of the CentOS 7 versions of Node. Please feel free to re-open if you're able to narrow this down to a specific release of Node.

I had the same story with CentOS 7 and zlib 1.2.7
I tried to update system zlib which as a very bad idea. My VPS stopped work at all, then I recover the server with backup and stumble upon this article: https://unix.stackexchange.com/questions/476450/trying-to-resolve-dependency-on-libz-so-1zlib-1-2-9

I just repeat the answer that helped me out:

I created these directories:

mkdir /opt/zlib
cd /opt/zlib
mkdir /1.2.11
mkdir /src

I then moved into /opt/zlib/src and:

wget https://github.com/madler/zlib/archive/v1.2.11.tar.gz

I then decompressed it and moved into the directory containing the config just as I'm sure you did and then ran this:

tar -zxf v1.2.11.tar.gz
cd zlib-1.2.11
./configure --prefix=/opt/zlib/1.2.11

Then I ran make and make install.

make; make install;

That put the libraries in:

/opt/zlib/1.2.11/lib

I then ran this command to see ZLIB_1.2.9 available:

strings -d /opt/zlib/1.2.11/lib/libz.so | grep ^ZLIB

Lastly, I modify ~/.bashrc and append this:

export LD_LIBRARY_PATH=/opt/zlib/1.2.11/lib:/usr/lib64:$LD_LIBRARY_PATH

After this steps problem disappeared.
