Hey everyone,
I’m encountering an issue while building my Docker image, and I’d appreciate some help troubleshooting it.
Problem: During the Docker build process, I’m consistently getting an error stating “moc not found,” which halts the build process. Here’s the specific error message:
bashCopy code
/bin/sh: 1: /root/.cache/dfinity/versions/0.19.0/moc: not found
ERROR: moc not found. Please check your DFINITY SDK installation.
Dockerfile:45
--------------------
43 |
44 | # Use ic-mops to install Motoko package dependencies
45 | >>> RUN mops install
46 |
47 | # Expose any ports your app needs (adjust as necessary)
--------------------
ERROR: failed to solve: process "/bin/sh -c mops install" did not complete successfully: exit code: 1
Context: I’m using a Dockerfile to set up my development environment. In the Dockerfile, I’ve included commands to install the DFINITY Canister SDK (dfx) and other dependencies required for my project. When i try running the global instalation for mops (motoko package manager), it outputs an error regarding the location of the compiler (moc).
Troubleshooting Steps Taken:
- Verified that the DFINITY SDK installation completes without errors.
- Checked the expected installation path for
mocafterdfxinstallation. - Attempted to directly check for
mocusing thefindcommand in the Dockerfile. - Ensured that the Dockerfile environment is correctly configured to locate
moc.
Request for Assistance: Despite these steps, I’m still encountering the “moc not found” error during the Docker build. I’d appreciate any insights or suggestions on how to resolve this issue.
Dockerfile Snippet: Here’s the relevant part of my Dockerfile for reference:
DockerfileCopy code
# Start with the official Node.js base image to get the latest npm along with Node.js
FROM node:latest
# Install system dependencies required for the DFINITY Canister SDK and general development
RUN apt-get update && apt-get install -y \
curl \
git \
build-essential \
libssl-dev \
pkg-config \
cmake \
&& rm -rf /var/lib/apt/lists/*
# Set the environment variable to non-interactively agree to the installation prompts
ENV DFXVM_INIT_YES=true
# Install the DFINITY Canister SDK
RUN curl -fsSL https://internetcomputer.org/install.sh | sh \
&& echo "Install script exit code: $?"
# Define the DFX_PATH environment variable and add it to PATH
ENV DFX_PATH="/root/.local/share/dfx/bin"
ENV PATH="$DFX_PATH:$PATH"
# Verify dfx installation and check if moc is installed correctly
RUN curl -fsSL https://internetcomputer.org/install.sh | sh \
&& echo "Install script exit code: $?"
# Attempt to load the environment and check for `moc`
RUN bash -lc "dfx --version && find / -name moc 2>/dev/null"
# Install ic-mops globally
RUN npm install -g ic-mops
# Set the working directory in the Docker container
WORKDIR /app
# Copy your project files into the working directory
COPY . .
# Install project dependencies including Node.js packages
RUN npm install
# Use ic-mops to install Motoko package dependencies
RUN mops install
# Expose any ports your app needs (adjust as necessary)
EXPOSE 8000
# Commands to run your app
# Assuming dfx, generate, copy commands and deploy commands are needed
RUN dfx start --background --clean \
&& dfx generate \
&& cp src/declarations/users/* .dfx/local/canisters/users/ \
&& cp src/declarations/user_index/* .dfx/local/canisters/user_index/ \

&& cp src/declarations/http_service/* .dfx/local/canisters/http_service/ \
&& dfx deploy
# CMD to keep the container running
Conclusion: If anyone has encountered a similar issue or has any suggestions on how to resolve it, I’d greatly appreciate your input. Thank you in advance for your help!
