# ENOENT: PS, Spawn PS - Common Issues when Working with Nestjs, Nodejs and Docker

Working Environment:

- VsCode
- Debug Mode
- Nestjs
- Dockerfile

What did that happened?

After i ran docker compose up and then i change some file content in my local machine , it will trigger changed in the file system between local and remote host.

Error message:

Problem: The problem is the docker container image you're using is missing procps

Solution:

<div id="bkmrk-insert-this-line-int">Insert this line into your dockerfile:</div><div id="bkmrk-"></div>```
RUN apt-get update && apt-get install -y procps
```

Example:

```
FROM node:21-bullseye-slim as development

RUN apt-get update && apt-get install -y procps

WORKDIR /usr/src/app

COPY package.json ./
COPY tsconfig.json tsconfig.json
COPY nest-cli.json nest-cli.json
COPY apps/auth/prisma ./prisma
```
