Argon2 with node docker container

I have NestJs application that works perfectly on my local machine (windows). Now I would like to create a docker container for my application. When i try to start my container i have one issue with Argon2. I install on the container all the argon needs. where's my mistake?

Thank

I also had this issue I did the above tip by Jay McDoniel. Although for me I also had another problem that seemed to have thrown the same error. The problem for me was I accidentally npm installed something in my project while using a yarn project where I should have yarn added this gave a warning that said:

warning package-lock.json found. Your project contains lock files generated by    
tools other than Yarn. It is advised not to mix package managers in order to avoid 
resolution inconsistencies caused by unsynchronized lock files. To clear this. 
warning, remove package-lock.json.

The problem wasn't yet fixed until I removed package-lock.json (lesson learned: pick your least favorite of the two lockfiles (yarn.lock or package-lock.json) to remove from you project and always keep just one type of package manager in use between yarn and npm)

Answering for posterity sake:

Sounds like you have no .dockerignore file so when you COPY . . you are pulling over the node_modules folder from your local machine (Windows) and trying to run it in Docker (Alpine Linux), so while you correctly run npm install argon2 in the Docker context, you overwrite it when you copy from local to Docker. If you create a .dockerignore file, add /node_modules to it so that you don;t move the node_modules directory
