I set up a Docker Compose on my Linux (Kubuntu) laptop that includes a python container which runs Django and uses React for a Frontend. When I brought the Docker files over to my Windows 10 desktop, I am getting the following error:
/node_modules/.bin/../node/bin/node: 1: This: not found
I've checked Node and npm versions inside the container on each system; they are both v22.4.0 and 10.8.1 respectively, so versions does not seem to be the issue.
I've tried to set up this docker environment on a different Windows laptop, I am getting the same /node_modules/.bin/../node/bin/node: 1: This: not found error, which suggests to me that this is a Linux-Windows issue, not something specific to my desktop.
I've found an existing StackOverflow question with no answer and another with only a comment that led to a GitHub issue on the now-archived npm repo, but none of these seem to apply to Docker. I tried to follow the directions that seemed to solve the issue for most people in the GitHub issue, but I am using nvm on my Windows machine and do not have a C:/Users/{username}/AppData/Roaming/npm or C:/Users/{username}/AppData/Roaming/npm-cache folder to delete. I did try changing my Node version using nvm, but the error persists. I'm also not convinced that the error should be happening in a Docker container even if there was an issue with Node/npm on my Windows system; the Docker is installing Node directly from source (see below for details).
I'm at a bit of a dead end of what else to check, suggestions appreciated.
All the details can be seen at my GitHub branch for trying to get this up and running, but I'll include the Dockerfile for the affected container as well as the compose file here for convenience. GitHub is not tracking my node_modules directory because it's so large, but if I should include details about that let me know and I will provide them. My package.json and package-lock.json can be found in the Frontend directory.

Figured it out -- the problem here is that my project directory was copied into the container (COPY . /home/appuser/) including the node_modules folder on my Windows machine. This Windows node_modules folder in the Linux environment was causing problems with npm, which was getting confused about context.
In my case, the easiest solution was to just delete the node_modules folder on my Windows machine, but generally just exclusing it from being copied into the Linux container should work (or maybe deleting it from the Linux container after copying project files, but that seems like a huge waste of time, given that when node_modules is included, it outweighs all the code I've written on this project, so copying and then deleting most of the data seems wasteful... But you know your project, maybe it makes sense for you).
