------------------------------------
some unproper part by [~vthinkxie]
1.node-sass/v4.11.0/linux-x64-72_binding.node` is not the static file, the file
position and name is determined *{color:#de350b}by your npm{color}* and node
version dynamically, which means *{color:#de350b}that it will always have an
error if you have installed unmatched node or npm version yourself. That is why
it works fine in every other' and ci environment except yours{color}*.(just
imagine that you have installed many different versions of maven and want them
to work together in the same command line, which is impossible.)
*version defined by package.json*
*sub-version defined by node_modules/.../install.js*
*please understand that every one want to obey the matched node version.*
*but new linux system core don't always have that
compatibility({color:#de350b}such as core dumped{color} from npm with
flink-needed node.js)*
2.the node and npm version are managed by maven-frontend-plugin in the
flink-runtime-web/pom.xml in isolated
folders(flink-runtime-web/web-dashboard/node and
flink-runtime-web/web-dashboard/node_modules), if you want to manage it
yourself(try to run npm ci or npm install yourself), *DON'T DO THIS* until you
have full knowledge of npm and node package, it would mess up the isolated env
of node and npm.
{color:#de350b}*it's not a must to have full knowlege to build this,just 3
steps in above link.*{color}
# plz have a try to remove all your `flink-runtime-web/web-dashboard/node` and
`flink-runtime-web/web-dashboard/node_modules` caches in the
flink-runtime-web/web-dashboard and have a try again.
