RUN npm -v
RUN git clone --depth 1 https://github.com/ONLYOFFICE/server.git
RUN cd server/SpellChecker && \
npm install
```
In this Dockerfile - npm v7.5.4 installed and causing:

```
But if we force npm v6:
```
FROM node:10
RUN npm install -g npm@6
RUN npm -v
RUN git clone --depth 1 https://github.com/ONLYOFFICE/server.git
RUN cd server/SpellChecker && \
npm install
```
Forcing install of npm v6.14.11 and server Spellchecker
compilation is fine
