我尝试在 package.json 中设置 git 依赖项：

"dependencies": {
    "myLib": "git+ssh://git@domain.com:user/myLib.git"
  }

当我这样做时，sudo npm install我收到错误：

Warning: Permanently added the RSA host key for IP address 'myIp' to the list of known hosts.

 Permission denied (publickey).

尽管我可以成功地将相同的库克隆到该机器：

git clone git@domain.com:user/myLib.git

所以我有有效的 ssh 密钥。

我的操作系统是OSX ，但我在Linux上也有同样的问题。

有时当我在Sublime text2中编辑coffeescript文件时,我将它编译为js时出错:

error: unexpected INDENT
                        $.post url,

在sublime text2编辑器中,我看到有效的缩进:

但是,如果我在普通编辑器中复制粘贴此代码,我会看到错误的缩进:

click: ->
                            debugger;
                        # delete org here
                        $.post url,

debugger; 字符串有错误的额外缩进.

那么如何高兴地编辑sublime text 2中的coffeescript文件呢？我在sublime中安装了coffeescript包.

我的Preferences.sublime-settings文件如下:

{
    "auto_indent": true,
    "auto_match_enabled": true,
    "detect_indentation": true,
    "draw_centered": false,
    "font_size": 11.0,
    "ignored_packages":
    [
        "Better CoffeeScript",
        "Vintage"
    ],
    "indent_guide_options":
    [
        "draw_active"
    ],
    "indent_subsequent_lines": true,
    "indent_to_bracket": true,
    "smart_indent": true,
    "tab_size": 2,
    "translate_tabs_to_spaces": true,
    "trim_automatic_white_space": true,
    "use_tab_stops": true,
    "word_wrap": "auto",
    "wrap_width": 0
}

我用一个方法及其别名创建了一个coffeeScript类:

 class Class1
   method1 : (param1)=>
     console.log param1
   aliasForMethod1: @method1

 module.exports = Class1

它输出javascript:

 // Generated by CoffeeScript 1.6.2
    (function() {
      var Class1,
        __bind = function(fn, me){ return function(){ return fn.apply(me, arguments); }; };

      Class1 = (function() {
        function Class1() {
          this.method1 = __bind(this.method1, this);
        }

        Class1.prototype.method1 = function(param1) {
          return console.log(param1);
        };

        Class1.prototype.aliasForMethod1 = Class1.method1;

        return Class1;

      })();

      module.exports = Class1;

    }).call(this);

尝试使用这个类:

 Class1 = require './class1'

 instanceOfClass1 = new Class1()

 instanceOfClass1.method1()
 instanceOfClass1.aliasForMethod1()

但得到错误:

$ node /pathToMyClassUser/class1_user.js
undefined

 /pathToMyClassUser/class1_user.js:11 …

我想使用正则表达式来显示错误消息......

try {
  throw new Error("Foo 'bar'");
} catch (err) {
  console.log(getInQuotes(err));
}

...其中 getInQuotes 是字符串函数：

var getInQuotes = function(str) {
  var re;
  re = /'([^']+)'/g;
  return str.match(re);
};

...但出现错误：

Object Error: Foo 'bar' has no method 'match'

虽然它适用于普通字符串：

console.log(getInQuotes("Hello 'world'"));

结果：

[ '\'world\'' ]

尝试将错误对象字符串化...

console.log("stringify: " + JSON.stringify(err));

...但它是空的：

stringify: {}

如何在sublime text 3插件中获取所选文本:

import sublime, sublime_plugin

class plugin_window__go_to_relative_plugin__Command(sublime_plugin.WindowCommand):
    def run(self):            
        window = self.window
        view = window.active_view()
        sel = view.sel()
        sublime.status_message("selection: "+sel)

我的代码抛出错误:

     sublime.status_message("selection: "+sel)
TypeError: Can't convert 'Selection' object to str implicitly

view.sel()返回sublime.Selection对象.但我不知道如何从那里获取选定的文本.

这个插件必须如下工作:当我在视图上调用它时...

...它应该将文本设置"dow = self.w"为变量sel

当我这样做str(sel)时返回<sublime.Selection object at 0x1047fd8d0>

对我来说,文档不是很清楚.

几天后我面临服务器磁盘溢出.在它充满10%之前.原因是文件newrelic_agent.log大小为5 - 30千兆字节.我在应用程序的文件nginx夹site-enabled和主目录中找到了这么大的文件node.js express.

{"name":"newrelic","hostname":"hostname","pid":355,"component":"redis","level":10,"msg":"Adding Redis command trace segment transaction 2769.","time":"2014-01-02T06:20:11.894Z","v":0}
{"name":"newrelic","hostname":"hostname","pid":355,"component":"redis","level":10,"msg":"Adding Redis command trace segment transaction 2769.","time":"2014-01-02T06:20:11.894Z","v":0}
{"name":"newrelic","hostname":"hostname","pid":355,"component":"redis","level":10,"msg":"Adding Redis command trace segment transaction 2769.","time":"2014-01-02T06:20:11.895Z","v":0}

在我删除这些文件后,我在一天中发现它们的规模如此糟糕.

如何在服务器上禁用此日志记录？我认为这是因为newrelic redis的关键插件.或者唯一的方法是关闭这个插件？

我想配置supervisord有golang web app根据的文章.但是当我运行命令时出错sudo supervisord -c /etc/supervisor/supervisord.conf:

Error: Invalid username deploy user # the user your app should run as (i.e. *not* root!)

我创建了用户deployuser并将其添加到组中supervisor

sudo adduser deployser supervisor

Supervisord配置文件是

[unix_http_server]
file=/var/run/supervisor.sock   ; (the path to the socket file)
chmod=0770                       ; sockef file mode (default 0700)
chown=root:supervisor            ; add our group
[supervisord]
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor            ; ('AUTO' child log dir, default $TEMP) …

我试图从golang测试重复示例

package main

import (
    "testing"
)

func TestSomeTest(t *testing.T) {}

func TestMain(m *testing.M) { // cleaning after each test}

我想TestMain在每次测试后运行函数.

运行命令 go test

而编译器说

./testingM_test.go:9: undefined: testing.M

那么在执行每个测试后如何清理？

我有一个以上的IP去互联网.我正在请求选择界面.在这种情况下,我应该如何设置标题？

tcpAddr := &net.TCPAddr{
    IP: addrs[3].(*net.IPNet).IP, // Choosing ip address number 3
}
d := net.Dialer{LocalAddr: tcpAddr}
conn, err2 := d.Dial("tcp", "www.whatismyip.com:80")
if err2 != nil {
    log.Fatal(err2)
}

defer conn.Close()

transport := &http.Transport{
    Proxy:               http.ProxyFromEnvironment,
    Dial:                (&net.Dialer{LocalAddr: tcpAddr}).Dial,
    TLSHandshakeTimeout: 10 * time.Second,
}

client := &http.Client{
    Transport: transport,
}

response, err := client.Get("https://www.whatismyip.com/")

通常标头以这种方式设置:

req.Header.Set("name", "value")

但无法弄清楚如何将它们设置为我的代码.

我想他们必须设置在某处http.Transport或http.Client.但到底怎么样？

我的完整代码:

    ctx, cancel := chromedp.NewContext(
        context.Background(),
        chromedp.WithLogf(log.Printf),
    )
    defer cancel()

    // create a timeout
    ctx, cancel = context.WithTimeout(ctx, 15 * time.Second)
    defer cancel()

    u := `https://www.whatismybrowser.com/detect/what-is-my-user-agent`

    var result string
    err := chromedp.Run(ctx,
        chromedp.Navigate(u),
        chromedp.WaitReady(selector),
