I am trying to build a dockerfile but the problem is when it trying to build specifically cryptography is not building.
MY Dockerfile
FROM python:3.7-alpine
ENV PYTHONUNBUFFERED 1
RUN apk update \
# psycopg2 dependencies
&& apk add --virtual build-deps gcc python3-dev musl-dev\
&& apk add postgresql-dev \

when I try to build my dockerfile it shows:
Building wheel for cryptography (PEP 517): finished with status 'error'
ERROR: Command errored out with exit status 1:
error: Can not find Rust compiler
----------------------------------------
ERROR: Failed building wheel for cryptography
I tried to solve but i couldn't. I am newbie in docker.Please help how to get rid of this problem.
Since the error is...
error: Can not find Rust compiler
...the solution is to install the rust compiler. You'll also need
cargo
, the Rust package manager, and it looks like your Dockerfile
is missing openssl-dev
.
The following builds successfully for me:
FROM python:3.7-alpine
ENV PYTHONUNBUFFERED 1
RUN apk add --update \
build-base \
cairo \
cairo-dev \
cargo \
freetype-dev \
gcc \
gdk-pixbuf-dev \
gettext \
jpeg-dev \
lcms2-dev \
libffi-dev \
musl-dev \
openjpeg-dev \
openssl-dev \
pango-dev \
poppler-utils \
postgresql-client \
postgresql-dev \
py-cffi \
python3-dev \
rust \
tcl-dev \
tiff-dev \
tk-dev \
zlib-dev
RUN pip install cryptography
Note that the above apk add ...
command line is largely the same as
what you've got; I've just simplified the multiple apk add ...
statements into a single apk add
execution.
