elm 安装elm/http

Answer 1

运行 elm install 没有任何输入的命令将给出以下提示

Hint: In JavaScript folks run npm install to start projects. "Gotta download everything!" But why download packages again and again? Instead, Elm caches packages in /Users/kaskelotti/.elm so each one is downloaded and built ONCE on your machine. Elm projects check that cache before trying the internet. This reduces build times, reduces server costs, and makes it easier to work offline. As a result elm install is only for adding dependencies to elm.json, whereas elm make is in charge of gathering dependencies and building everything. So maybe try elm make instead?

正如提示所说，elm make 可能就是您所需要的。

如果您的 elm 缓存缺少某些依赖项，将根据需要下载它们。
