试图使用灯箱与clojure离线 - Windows 7没有互联网(trying to use lighttable with clojure offline - windows 7 w/o internet)

LightTable似乎将自己的clojure lein和maven系统设置为REPL。 我试图使用它的计算机没有Internet访问权限。 有没有办法让我手动下载所需的插件并将它们包含在light table创建的.m2存储库中?

这是我得到的错误:

我们无法连接。

看起来尝试连接到项目时出现问题。 这是我们得到的:

LightTable能够在我的用户文件夹中的.m2目录中创建空目录。 它看起来像是那里的一部分,我只是想帮助它。

如果它很重要我安装了leiningan并且能够使用它,当然它只能用作项目制造商/ REPL启动器。


[编辑]

通过将我的.m2文件夹从另一台计算机上的LightTable复制到我的Windows计算机上的文件夹,我取得了一些进步。 现在我只有两条错误消息:

我们无法连接。

看起来尝试连接到项目时出现问题。 这是我们得到的:

关于如何解决这两个问题的任何想法? 他们都明显地坐在我的.m2文件夹中,还有pom和all。


LightTable seems to setup its own clojure lein and maven system to be a REPL. The computer I am trying to use it on does not have internet access. Is there a way for me to manually download the needed plugins and include them in light table created .m2 repository?

This is the error I get:

We couldn't connect.

Looks like there was an issue trying to connect to the project. Here's what we got:

Could not transfer artifact lein-light:lein-light:pom:0.0.32 from/to central (http://repo1.maven.org/maven2/): Connection to http://repo1.maven.org refused Could not transfer artifact org.clojure:clojure:pom:1.5.1 from/to central (http://repo1.maven.org/maven2/): Connection to http://repo1.maven.org refused Could not transfer artifact org.clojure:tools.nrepl:pom:0.2.3 from/to central (http://repo1.maven.org/maven2/): Connection to http://repo1.maven.org refused Could not transfer artifact clojure-complete:clojure-complete:pom:0.2.3 from/to central (http://repo1.maven.org/maven2/): Connection to http://repo1.maven.org refused This could be due to a typo in :dependencies or network issues.

LightTable was able to create empty directories in an .m2 directory in my user folder there. It looks like its part of the way there and I'd just like to help it along a bit.

If it matters I do have leiningan installed and am able to use it, of course its only usable as a project maker/REPL starter.


[EDIT]

I've made a little bit of progress by copying over my .m2 folder from a working LightTable on another computer to the one on my windows computer. Now I only have two error messages:

We couldn't connect.

Looks like there was an issue trying to connect to the project. Here's what we got:

Any ideas as to how I can resolve these last two? They are both clearly sitting in my .m2 folder with pom's and all.

最满意答案

据我了解,你想关闭文件流出使用?

你不需要明确地关闭它。 std::fstream是RAII对象,所以它将在封闭范围的末尾自动关闭打开的文件。

当然,如果你真的需要关闭文件,你总是可以抛出:

if( ptr = dynamic_cast<std::ofstream*>(out) ) {
    ptr->close();
}

As I understood you want to close file stream using out?

You don't need to close it explicitly. std::fstream is RAII object, so it will close an opened file automatically at the end of enclosing scope.

And of course, you can always cast out if you really need to close the file just now:

if( ptr = dynamic_cast<std::ofstream*>(out) ) {
    ptr->close();
}
