我不能让我的mysql从os x 10.7开始.它位于/usr/local/mysql/bin/mysql

当我输入mysql --version终端时,我找不到命令.

我试过这不能从命令行mac访问mysql但仍然找不到命令.我尝试用dmg安装mysql,我试图通过自制程序安装它,我无法让它工作.当我尝试用自制软件启动mysql时,我得到MySQL将无法启动

这是我的$PATH:

在/ usr/bin中:/ bin中:/ usr/sbin目录:/ sbin目录:在/ usr/local/bin目录:在/ usr/X11/bin中:在/ usr /本地/ git的/ bin中:/用户/维多利亚/斌:在/ usr /本地// USR /本地/ MySQL的/斌/私人的/ var/mysql的/私人的/ var/mysql的/ bin中

当我尝试在Ubuntu中启动Apache时,我收到此错误.

 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
 no listening sockets available, shutting down
 Unable to open logs
 Action 'start' failed.

我在ports.conf中有这个

NameVirtualHost *:80
Listen 80

这是我的vhost文件

<VirtualHost *:80>
          ServerAdmin example@example.com
          ServerName rails.server.com
          # ServerAlias
          DocumentRoot /var/www/sample_app/current/public
          ErrorLog /var/www/sample_app/error.log

          RailsEnv production
        <Directory "/var/www/sample_app/current/public">
          Options Indexes FollowSymLinks MultiViews
          Order allow,deny
          Allow from all
        </Directory>
</VirtualHost>

我错过了什么？

我只是设置我的mac进行开发,并使用此精确的gemfile以前它工作正常.我不确定我做错了什么.

当我尝试运行部署设置时,为什么会出现authenicationFailed？我使用ssh作为我的密码.我是否需要更改database.yml或deploy.rb中的任何内容.它们列在下面.

我正进入(状态

cannot load such file -- bootstrap/sass

我已经安装了bootstrap-sass-2.0.3.1,sass-3.1.18,sass-rails-3.2.5,coffee-rails-3.2.2和uglifier-1.2.4

为什么我会收到此错误？

它默认为Mac OS x附带的1.8.7.我试图使用RVM并使用1.9.3我试过rvm使用默认值并且说-bash:rvm:command not found

我的bashrc文件有

PATH=$PATH:$HOME/.rvm/bin 

我是c ++的新手,我正在尝试从值50开始增加汽车,但如果youdamage比greamage更好,那么只增加一个.我希望汽车在下一次循环时保持其价值.我希望这是有道理的.

int Power (int &car);

int main(){
    int car = 50;
    // ...
    // ...
    // ...

    int carDamage = 0;
    int yourDamage = 0;
    // pick a random number between 1 to 50
    yourDamage = 0 + rand() % (50 - 0 + 1);
    carDamage = 0 + rand() % (50 - 0 + 1);
    cout << "You hit the car and cause damage of: " << carDamage << endl;

如何在测试时更改Sublime使用的Ruby版本.它目前使用1.8,但我希望它使用1.9.3,它在RVM中设置为我的默认值.当我键入哪个ruby时,我得到1.9.3,但是Sublime没有使用它.

我正在收到页面"我们很抱歉,但是当我尝试加载我的rails应用程序时出现了问题.当我运行时

tail -f log/production.log

我明白了

ActionView::Template::Error (rails.png isn't precompiled)

我跑了

 RAILS_ENV=production rake assets:precompile

从当前目录.

我究竟做错了什么？我认为我的所有目标都是正确的.我收到此错误

describe "visiting the edit page" do

describe "submitting to the update action" do

describe "visiting the user index" do

describe "as wrong user" do

FactoryGirl.create(:user, email: "wrong@example.com")}

和

describe "visiting Users#edit page" do

这是我运行rspec时遇到的错误
