I am trying to build a docker image using open zepplin libraries. It works until it has to import the zepellin library, for which it can't seem to find.
Here is what my docker image looks like :
FROM node:10-alpine
WORKDIR /usr/src/app
ENV UV_THREADPOOL_SIZE 64
COPY cdp-contracts/ ./rpc
COPY cdp-platform/ ./backend
RUN rm -rf backend/node_modules
RUN rm -rf rpc/node_modules
RUN apk add --no-cache --virtual .gyp \
autoconf \
automake \
g++ \
libpng-dev \
libtool \
make \
nasm \
python \
git \
&& npm i -g wait-on concurrently truffle npm@latest \
&& concurrently 'cd rpc; npm init -y ; npm install --save-exact openzeppelin-solidity; npm init -y ; npm i npm@latest -g ' 'cd backend; npm i npm@latest -g ; npm rebuild bcrypt --build-from-source' \
&& apk del .gyp
WORKDIR /usr/src/app/rpc
RUN truffle compile --all
WORKDIR /usr/src/app/backend
RUN mkdir -p build/
RUN ln -sf ../../rpc/build/contracts build/contracts
WORKDIR /usr/src/app/backend
EXPOSE 3001
CMD [ "npm", "run", "middleware" ]
Here is the import line from my contract :
import "../node_modules/openzeppelin-solidity/contracts/token/ERC20/ERC20.sol";
Note: From the documentation:
After that, you'll get all the library's contracts in the node_modules/openzeppelin-solidity/contracts folder. Because Truffle and other Ethereum development toolkits understand node_modules, you can use the contracts in the library like so
import 'openzeppelin-solidity/contracts/ownership/Ownable.sol'; contract MyContract is Ownable { ... }
Reference: https://openzeppelin.org/api/docs/get-started.html
When I try to reference the node module, or call it import it as above, I keep running into this error:
Error: Could not find /usr/src/app/rpc/node_modules/openzeppelin-solidity/contracts/token/ERC20/ERC20.sol from any sources; imported from /usr/src/app/rpc/contracts/CarbonToken.sol at /usr/local/lib/node_modules/truffle/build/webpack:/packages/truffle-resolver/index.js:76:1
I will appreciate any guidance on this
