如何在leiningen中使用Clojure`use`函数？ [英] How do I use the Clojure `use` function in leiningen?

问题描述

我对Clojure和Leiningen都很新。我已经安装Clojure在Windows上 C：\clojure-1.5.1 和leiningen-win-installer beta1在 C：\.lein\\ \\ bin 。

I am very new to both Clojure and Leiningen. I have installed Clojure on Windows at C:\clojure-1.5.1 and leiningen-win-installer beta1 at C:\.lein\bin.

现在我正在尝试Eric Rochester的书的例子。我在project.clj中包含了Incanter的依赖库，并且使用了dep。

Now I am trying the example from Eric Rochester's book. I have included dependent libraries for Incanter in project.clj and also using dep.

如何使用命令（使用'incanter.core） ？我得到'use'不被识别为内部或外部命令。此外，如何在 user => ？

How do I use the command (use 'incanter.core)? I am getting 'use' is not recognized as an internal or external command. In addition, how do I use lein commands at user=>?

使用lein命令谢谢！

Thanks!

推荐答案

编辑 - 我忘了lein deps，直到我看到Mars的回答

Edit - I forgot "lein deps" until I saw Mars's answer

启动lein repl，你必须使项目（lein new getting-data或任何书中的内容）。

Before you start lein repl, you have to make the project (with "lein new getting-data" or whatever is in the book).

这将创建一个新目录，并在该目录中找到并编辑project.clj以包含依赖关系（如书中所示）。

That makes a new directory, and in that directory you find and edit "project.clj" to include the dependencies (as shown in book).

cd进入project.clj所在的目录，并从dos / powershell提示符运行lein deps。

cd into the directory that project.clj is in and run "lein deps" from the dos/powershell prompt.

那么当您在同一个目录中运行lein repl时，在user =>提示符下，执行

THEN when you run lein repl, from within that same directory, at the user=> prompt, do

(use 'incanter.core) 

它会回到nil，你会运行。你可能希望先从leiningen页面运行一些例子，以获得更多的lein感觉。你总是在user =>提示符处键入clojure命令，而不是在c：....>提示符处。

and it will come back with "nil" and you'll be running. You might want to first run some examples from the leiningen page to get more of a feel for lein. You always type clojure commands at the "user=>" prompt, not at the "c:....>" prompt.
