cap deploy:cold与Capistrano一起使用时，如何禁用db：migrate ？
在config / deploy.rb中，唯一的引用已deploy:migrate被注释掉，但它仍在尝试这样做：
bundle exec rake RAILS_ENV=production db:migrate
当出现错误时,有没有办法减少Ruby提供的输出量？
例如:
rspec bowling_spec.rb
/Users/snowcrash/.rvm/rubies/ruby-2.0.0-p195/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- bowling (LoadError)
from /Users/snowcrash/.rvm/rubies/ruby-2.0.0-p195/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require'
from /Users/snowcrash/Developer/Code/Ruby/RSpec/bowling_spec.rb:2:in `<top (required)>'
from /Users/snowcrash/.rvm/gems/ruby-2.0.0-p195/gems/rspec-core-2.14.2/lib/rspec/core/configuration.rb:896:in `load'

from /Users/snowcrash/.rvm/gems/ruby-2.0.0-p195/gems/rspec-core-2.14.2/lib/rspec/core/runner.rb:17:in `block in autorun'
我感兴趣的只是第一行cannot load such file -- bowling (LoadError).理想情况下,我希望Ruby不要吐出其余的部分from.
这可能吗？
我收到这个错误:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/lipo: can't open input file: /Users/snowcrash/Library/Developer/Xcode/DerivedData/MyApp-awldrudjpictkjfutpthiwoocing/Build/Intermediates/ArchiveIntermediates/MyApp/IntermediateBuildFilesPath/MyApp.build/Distribution-iphoneos/MyApp.build/Objects-normal/armv7/MyApp (No such file or directory)
有什么建议？
从命令行运行仪器给了我这个错误:
Instruments Trace Error : Target failed to run: The operation couldn’t be completed. (FBSOpenApplicationErrorDomain error 8.) : Failed to launch process with bundle identifier
知道问题是什么以及如何解决？
是否可以在项目视图中的Android Studio中复制文件？
当我右键单击文件时，在任何选项中都没有看到它。
如果有可能，您该怎么做？
提交应用时出现了一些错误.
知道如何修复此错误:
ERROR ITMS-90092: “This bundle is invalid. Apps that include an arm64 architecture are required to include an armv7 architecture.”
查看Xcode中的有效架构我看到列出了armv7.所以有什么问题？
根据这个问题Access Denied for MYSQL ERROR 1045 I should be able to start MySQL in safe mode with
sudo mysqld_safe --skip-grant-tables
但这只是将以下几行记录到 STDOUT：
151116 17:46:46 mysqld_safe Logging to '/usr/local/var/mysql/MacBook-Pro.local.err'.
151116 17:46:46 mysqld_safe Starting mysqld daemon with databases from /usr/local/var/mysql
151116 17:46:46 mysqld_safe mysqld from pid file /usr/local/var/mysql/MacBook-Pro.local.pid ended
并将我返回到命令行。引用的错误日志在此处具有相同的最后 2 行输出。当我尝试连接到 MySQL 时，我得到：
mysql -uroot -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
如果我使用以下命令启动Docker容器：
docker run -it ubuntu /bin/bash
然后退出。我可以看到使用的容器
docker ps -a
但是，如果我尝试重新启动容器
docker start <container ID>
我只是被回显并返回到命令提示符。
我想念什么？
有没有简单的方法来调试 Doctrine 无法连接到 MySQL 的原因？
config.yml有：
# Doctrine Configuration
doctrine:
dbal:
driver: pdo_mysql
host: "%database_host%"
port: "%database_port%"
dbname: "%database_name%"
user: "%database_user%"
password: "%database_password%"
并且parameters.yml似乎有正确的连接信息。例如
parameters:
database_host: 127.0.0.1
database_port: null
database_name: <my database name>
database_user: <my database user>
database_password: <my database password>
然而这段代码仍然回显“未连接”。
$cnx = $this->getDoctrine()->getConnection();
if ($cnx->isConnected()){
echo "Connected";
}
else {
echo "Not connected";
}
并且我没有收到任何返回的错误。
有什么建议么？
