如果它不存在,我正在尝试创建一个完整的路径.
代码如下所示:
var fs = require('fs');
if (!fs.existsSync(newDest)) fs.mkdirSync(newDest);
只要只有一个子目录(像'dir1'这样的newDest),这个代码就可以运行,但是当有一个类似于''dir1/dir2'的目录路径时,它会失败并显示 错误:ENOENT,没有这样的文件或目录
我希望能够根据需要使用尽可能少的代码行创建完整路径.
我读到fs上有一个递归选项,并尝试这样做
var fs = require('fs');
if (!fs.existsSync(newDest)) fs.mkdirSync(newDest,'0777', true);
我觉得递归创建一个不存在的目录应该很简单.我是否遗漏了某些内容或是否需要解析路径并检查每个目录并创建它(如果它尚不存在)？
我是Node的新手.也许我正在使用旧版本的FS？
程序集绑定日志查看器(fuslogvw)不记录我机器上安装的任何框架版本的绑定.
我尝试使用自定义日志位置,默认日志位置,默认类别和本机图像类别.
装配绑定日志查看器几个月前就已运行.我在64位计算机上运行C:\ Program Files(x86)\ Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\x64\FUSLOGVW.exe
如何创建ELMAH SQL Server数据库？我通过NuGet将它添加到我的ASP.NET MVC项目中,并且我的机器上没有sql脚本.
我想使用Sublime Text 2来构建我的Visual Studio 2010解决方案.
到目前为止我有这个:
菜单项工具>构建系统>新构建系统...
{
"cmd": ["c:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\MSBuild.exe"]
}
我收到此错误:
MSBUILD:错误MSB1003:指定项目或解决方案文件.当前工作目录不包含项目或解决方案文件.
我想知道如何在构建文件中指定项目文件夹目录.
在我的博客文章索引中,我想从帖子中抓取第一张图片,只使用液体在索引中显示它,因此它适用于github页面.
我有一种感觉分裂是要走的路,但我对液体不好.
我希望能够获取图像URL并将其放入变量中以对其进行样式设置.
理想的解决方案是:
{% for post in site.posts %}
<li>
<a href="{{ post.url }}">{{post.content | first_image}}</a>
</li>
{% endfor %}
有任何想法吗？
我想把我的拼写检查结果输出到控制台而不是文件,我认为这应该有效,因为据我了解它gulp返回一个流.
相反,我得到一个错误:
TypeError: Object #<Stream> has no method 'read'
这是我的代码
gulp.task('spellcheck', function() {
var patterns = [{
// Strip tags from HTML
pattern: /(<([^>]+)>)/ig,
replacement: ''
}];
var spellSuggestions = [{
pattern: / [^ ]+? \(suggestions:[A-z, ']+\)/g,
replacement: function(match) {
return '<<<' + match + '>>>';
}
}];
var nonSuggestions = [{
pattern: /<<<.+>>>|([^\s]+[^<]+)/g,
replacement: function(match) {
if (match.indexOf('<') == 0) {
return '\n' + match + '\n';
}
return '';
}
}];
var toConsole = gulp.src('./_site/**/*.html')

有没有办法在没有每个图像的HTTP调用的情况下嵌入图像？我不希望这样,因为我认为它会导致可扩展性问题,而且图像也很敏感.
这是我的代码,它给出了IOException:

我得到了这个结果: System.ArgumentException: Object serialized to String. RavenJObject instance expected.
这是我的代码
public class Store
{
private static IDocumentStore store = createStore();
private static EmbeddableDocumentStore createStore()
{
var returnStore = new EmbeddableDocumentStore();

returnStore.Initialize();
return returnStore;
}
public static void Write(string value)

似乎根本原因在于RavenJObject如何工作,因为它抛出相同的错误:
RavenJObject storeMe = RavenJObject.FromObject("errors", new JsonSerializer());
如何在RavenDB中进行自定义序列化？
如何在Jekyll中关闭智能引号和撇号？这打破了我的吞噬拼写过程.
我想要一句话doesn't直接引用.相反,Jekyll正在将它们转换为智能引号doesnt’,我需要它们保持单引号进行拼写检查.
