node.js environmental problems

[xh2ctrl]

Now I used the docker image witcherfuzz/nodejs by "docker pull witcherfuzz/nodejs"
Here are the versions:

• node v14.0.0-pre
• npm 6.14.4

The issue occurs while trying to run the Request Crawler
node main.js request_crawler http://localhost /openemr/user --no-headless
After I installed the the required dependencies with internet connection, such as [email protected]
Here are the problems:

• Variations in import and export method between commonJS module and ES6 module
• Syntax mismatch, such as class private function names with #prefix, use of "??=", and so on.

What should I do, update node version or install the old version package?

By the way, I have attempted to update the node, but I should update make, glibc at the same time, this is also complicated.
