我想知道，删除一个包含所有文件的目录最简单的方法是什么?

我使用的是rmdir(PATH。“/”。美元价值);要删除一个文件夹，但是，如果里面有文件，我根本不能删除它。

c++ 11向量有了新函数emplace_back。与依赖编译器优化来避免复制的push_back不同，emplace_back使用完全转发将参数直接发送给构造函数以就地创建对象。在我看来，emplace_back做了所有push_back能做的事情，但有时它会做得更好(但不会更差)。

我使用push_back的原因是什么?

我注意到在一些开源项目中经常提到pty和tty，谁能告诉我它们是什么意思，它们之间有什么区别?

成功克隆我的回购从heroku和添加另一个远程

1/ git clone git@heroku.com:[APP].git
2/ git remote add bitbucket ssh://git@bitbucket.org/[ACCOUNT]/[REPO].git
3/ git push bitbucket master

在运行line(3)或使用SourceTree后，我仍然得到这个错误

conq: repository access denied. access via a deployment key is read-only.

首先，我不明白这条信息在实践中意味着什么。这就是耻辱。

我确实创建了ssh密钥对并添加到heroku:

ssh-keygen -t rsa 
heroku keys:add ./id_rsa.pub 

我还在BitBucket的部署密钥部分添加了我的密钥。但我一定遗漏了什么。这个问题不是出于懒惰，我一直在阅读各种文档，包括BitBuckets指南。但它仍然没有解决这个问题。

这篇文章是有关我可以导入我的heroku git回购到bitbucket ?以及如何?

额外的事实:

ssh -T hg@bitbucket.org
conq: authenticated via a deploy key.

You can use git or hg to connect to Bitbucket. Shell access is disabled.

如何通过ssh连接到AWS实例?

我遇到了一些麻烦，让两个不同的SSH密钥/GitHub帐户一起玩得很好。我有以下设置:

使用git@github.com:accountname从一个帐户访问回购

从另一个帐户使用git@github.com:另一个帐户访问回购

每个帐号都有自己的SSH密钥。两个SSH密钥都已经添加，我已经创建了一个配置文件。我不相信配置文件是正确的。我不太确定如何指定使用git@github.com:accountname访问的回购应该使用id_rsa和git@github.com:anotheraccount应该使用id_rsa_anotheraccount。

declare关键字的含义是什么?

type Callback = (err: Error | String, data: Array<CalledBackData>) => void;

vs.

declare type Callback = (err: Error | String, data:Array<CalledBackData>) => void;

在TS中找不到解释declare关键字目的的文档。Qué signa ?

问题

如何从Subversion存储库中使用git-svn创建一个浅拷贝，例如，如何只提取最后三个修订?

如果你使用——depth选项，git clone命令可以从git存储库中获得最近的n个修订，也就是说，你可以获得存储库的浅拷贝。例子:

git clone --depth 3 git://some/repo myshallowcopyrepo

git-svn是否有类似的选项?

我目前的发现

到目前为止，我只找到了-rN选项，其中N是要拉的修订。例子:

git svn clone -rN svn://some/repo

根据文档，可以使用-r$REVNUMBER:HEAD。我尝试下面的3个版本，返回一个错误消息。

$ git svn clone --prefix=svn/ -s -rHEAD~3:HEAD http://some/svn/repo .
revision argument: HEAD~3:HEAD not understood by git-svn

所以我将HEAD~3替换为第三次也是最后一次修订534的实际数字。这是有效的，但这要求我首先计算出第三次(也是最后一次)提交的修订号。

$ git svn clone --prefix=svn/ -s -r534:HEAD http://some/svn/repo .

我生成了一个没有密码的SSH密钥对，并将公钥添加到GitHub。

与

user@dev:/var/www/project# ssh -T git@github.com
Hi User! You've successfully authenticated, but GitHub does not provide shell access.

当我重命名密钥时，它失败了。

但当我想要推送更改时，它仍然要求我输入用户名和密码组合。

有没有不用密码就能推的方法?

我已经通过bash创建了一个新的Foundation 5项目，使用Foundation new my-project。当我在Chrome中打开index.html文件时，Uncaught TypeError: a.c indeof不是一个函数错误，在控制台显示，源于jquery.min.js:4。

我按照基金会网站上的步骤创建了这个项目，但我似乎无法摆脱这个错误。Foundation和jQuery看起来在index.html文件中被正确地包含和链接，并且链接的app.js文件包括$(document).foundation();

有人知道是什么导致了这个错误吗?解决方案是什么呢?
