installing deno on alpine leads to deno: not found

[BlackScorp]

Hi all, i want to create a frontend service in a custom docker container but after installing deno, it is not found on cmd but the binary is there. maybe the binary is not compatible with alpine linux?

I use following Docker file

ARG ALPINE_VERSION=${ALPINE_VERSION:-latest}
FROM alpine:$ALPINE_VERSION


RUN apk -U upgrade
RUN apk add --no-cache \
    curl

RUN export DENO_INSTALL=/usr/local && curl -fsSL https://deno.land/install.sh |  sh

CMD ["tail","-f","/dev/null"]

the output of the installation is following

######################################################################## 100.0%
Archive:  /usr/local/bin/deno.zip
  inflating: deno
Deno was installed successfully to /usr/local/bin/deno
sh: /usr/local/bin/deno: not found
Run 'deno --help' to get started

you can already see here the not found error.

so i checked /usr/local/bin

total 138384
drwxr-xr-x    1 root     root          4096 Nov  9 21:22 .
drwxr-xr-x    1 root     root          4096 Sep  6 11:34 ..
-rwxr-xr-x    1 root     root     141686664 Nov  9 21:22 deno

the file is there and is executable

echo $PATH shows following

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

so executable is there but is for some reason it is not found. i cannot use alpines apk add deno because it is in version 1.4 and i would like to use the latest one.

maybe someone has an idea?

I'm running into the same issue, and I think it's something to do with this section of the install.sh basically skipping run_shell_setup which is where the PATH is updated with the location of deno

# If stdout is a terminal, see if we can run shell setup script (which includes interactive prompts)
if [ -z "$CI" ] && [ -t 1 ] && $exe eval 'const [major, minor] = Deno.version.deno.split("."); if (major < 2 && minor < 42) Deno.exit(1)'; then
	if [ -t 0 ]; then
		run_shell_setup "$@"
	else
		# This script is probably running piped into sh, so we don't have direct access to stdin.
		# Instead, explicitly connect /dev/tty to stdin
		run_shell_setup "$@" </dev/tty
	fi
fi

this should be fixed now by passing -y to the install script

for example

FROM debian:stable-slim

RUN apt-get update && \
  apt-get install -y \
  bash \
  curl \
  unzip

ENV SHELL="/bin/bash"

RUN curl -fsSL https://deno.land/install.sh | DENO_INSTALL=/usr/local sh -s -- -y

CMD ["/bin/bash"]

Actually, sorry that does not completely fix your issue. You're right, it seems like that alpine base image just doesn't have some dependencies that the deno binary needs.

ldd /usr/local/bin/deno returns

Otherwise, there is an official Deno Alpine image denoland/deno:alpine
