Can't install npm module on docker machine

Question

I'm new to Docker and I faced with a problem on windows,
I get an error while running npm i on my docker machine:

panel_1  | > [email protected] install /var/www/html/node_modules/phantomjs-prebuilt
panel_1  | > node install.js
panel_1  |
panel_1  | module.js:550
panel_1  |     throw err;
panel_1  |     ^
panel_1  |
panel_1  | Error: Cannot find module 'readable-stream'

panel_1  |     at tryModuleLoad (module.js:506:12)
panel_1  |     at Function.Module._load (module.js:498:3)

My compose:

  panel:
    build: './panel'
    volumes:
      - ./panel:/var/www/html
    command: make init_dev

My Dockerfile:

FROM php:7.2-fpm

RUN apt-get update && apt-get install -y \
    openssl \
    git \
    unzip \
    libzip-dev \
    wget \
    gnupg

# NodeJs
RUN wget -qO- https://deb.nodesource.com/setup_8.x | bash -

RUN apt-get install -y nodejs
RUN apt-get install -y build-essential

# Composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

RUN docker-php-ext-install mysqli pdo pdo_mysql zip bcmath

WORKDIR /var/www/html

makefile init_dev:

composer install
npm i
npm run dev

Already spent a day on resolving it. I tried to downgrade Phantomjs / upgrade npm / change permission for global node_modules but nothing helped. On local it's OK.

Just found that npm installation goes successful without using volumes .

Seems it happens due to windows mounted folder. Because there are no support for symlinks which npm is trying to add. My workaround looks like this:

COPY . /var/www/temp

WORKDIR /var/www/temp

RUN npm i

WORKDIR /var/www/html

And then I just do a copy of finished modules with CMD:

cp -r ../temp/node_modules ./

Looks like a crutch, but mb it'll help somebody
