Error while compiling with Docker (Spellchecker)

Do you want to request a feature or report a bug?
Bug

What is the current behavior?
The compilation with Docker (as described in build_tools fails with master branch and latest tag (v6.1.1, didn't checked earlier tags though). It seems like that building Spellchecker fails. See attached output.txt for more information.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.
As described in the build_tools repo, checkout build_tools

git clone https://github.com/ONLYOFFICE/build_tools

and build the DocumentServer with the given command

cd build_tools mkdir out docker build --tag onlyoffice-document-editors-builder . docker run -v $PWD/out:/build_tools/out onlyoffice-document-editors-builder

What is the expected behavior?
Successful build with output of the binaries in the folder "out".

Did this work in previous versions of DocumentServer?
I can't say this for sure as this is the first time I'm trying to compile the DocumentServer on my own.

DocumentServer version:
6.1.1

Operating System:
Debian 10 with the latest docker.io Package installed (= Docker Version 18.09.1).

The Dockerfile comes from the build_tools repo and is unchanged, which means it uses the ubuntu:14.04 Image for building.

Hi, we got same error recently and seems it's somehow related to npm v7
I see in your logs you're using npm v7 as well

We've downgraded to npm v6 like this #264 and everything seems fine

Thanks for your answer @ShockwaveNN

Indeed this is the problem. Maybe you can add this to the Readme in the Docker section? Just for the records, I solved the issue in manually changing the following line (No. 58) in the tools/linux/automate.py file:

base.cmd("sudo", ["npm", "install", "-g", "npm"])

to

base.cmd("sudo", ["npm", "install", "-g", "npm@6"])

@linuxrecon We already merged this to master several days ago, when we released v6.2.0
