deno in Dockerfile

i have successfully installed deno with theese commands:

# install denojs 
RUN curl -fsSL https://deno.land/x/install/install.sh | sh
ENV DENO_INSTALL /root/.deno
ENV PATH="$DENO_INSTALL/bin:$PATH"

# install denojs 
RUN curl -fsSL https://deno.land/x/install/install.sh | sh
ENV DENO_INSTALL /root/.deno
ENV PATH="$DENO_INSTALL/bin:$PATH"

in my Dockerfile, but when i try to run a script:

// export { Buffer } from "https://deno.land/std/node/buffer.ts";
import { Buffer } from "https://deno.land/std/node/buffer.ts";
console.log(Buffer)

// export { Buffer } from "https://deno.land/std/node/buffer.ts";
import { Buffer } from "https://deno.land/std/node/buffer.ts";
console.log(Buffer)

inside the virtual docker container i get the following message

Warning Implicitly using latest version (0.178.0) for https://deno.land/std/node/buffer.ts
error: Module not found "https://deno.land/std/node/buffer.ts".

Warning Implicitly using latest version (0.178.0) for https://deno.land/std/node/buffer.ts
error: Module not found "https://deno.land/std/node/buffer.ts".

what could be going on ?

i think the module is just down, it worked on my local machine because it was still in the cache , when i run the test with :

deno cache --reload tmp.js

deno cache --reload tmp.js

i also get the error on my physical machine visiting https://deno.land/std@0.178.0/node/buffer.ts shows a 404 Not Found message, i am going to report this

This script is not correct for several reasons. First of all, you should be using node specifiers:

import { Buffer } from "node:buffer"

import { Buffer } from "node:buffer"

if it was any other module, you should pin the version of the module. std/node was removed in deno 1.31.0

actually i had a unused import in my script, the module which depends on buffer.ts is this https://deno.land/x/mysql2 , exactly here : https://deno.land/x/mysql2@v1.0.6/deps.ts?source luckily i do not need this module, i just forgot to remove the import
