Rails 3.2.6:对于development.log文件，出现“无法访问日志文件"错误 [英] Rails 3.2.6: Getting 'Unable to access log file' error for development.log file

问题描述

这似乎是一个普遍的问题，但是我似乎无法通过Google搜索等找到解决方案.

This seems like it would be a common problem, but I just can't seem to find the solution through google searches, etc.

我刚刚创建了一个新的Rails 3.2.6应用程序，并将其配置为使用PostgreSQL数据库进行本地开发.我遵循了 RailsCast 的要求，并能够正确安装和设置所有内容.

I just created a new Rails 3.2.6 application and configured it to use the PostgreSQL database for my local development. I followed this RailsCast and was able to get everything installed and set up correctly.

但是，每当我尝试执行任何rails生成或rake命令(rails generate model，rake db:migrate等)时，都会出现以下错误，这些错误指向我的development.log文件:

However, whenever I try to do any rails generate or rake commands (rails generate model, rake db:migrate etc), I get the following error referring to my development.log file:

Rails Error: Unable to access log file. Please ensure that /Users/****/projects/rails_projects/rails_app/log/development.log exists and is chmod 0666. The log level has been raised to WARN and the output directed to STDERR until the problem is fixed.

我看到了其他这些stackoverflow问题/答案，但它们与我的情况不完全相同:

I see these other stackoverflow questions/answers, but they don't fit my case exactly:

• 轨道:无法访问日志文件<-返回在Rails 2.2时代
• Ruby on Rails设置:无法访问日志文件<-这是关于使用Apache的生产环境的信息.我在本地开发环境中.

• Rails: Unable to access log file <- This is back in the days of Rails 2.2
• Ruby on Rails Setup: Unable to access log file <- This is regarding a production environment using Apache. I am on a local development environment.

除了该错误外，我的应用程序运行正常.另外，如果我创建一个具有所有默认值的新Rails应用程序，则不会收到此错误.

Other than that error, my application runs fine. Also, if I create a new rails application with all its defaults, I don't get this error.

任何建议/提示将不胜感激.或者，如果您需要有关我的本地环境的更多信息，请告诉我.

Any suggestions/hints would be much appreciated. Or if you need any more information about my local environment, please let me know.

推荐答案

我基本上按照错误消息的建议进行操作，并对development.log文件进行了chmod 0666的操作:

I basically did what the error message suggested and did a chmod 0666 on the development.log file:

$> cd /Users/****/projects/rails_projects/rails_app/log/  
$> chmod 0666 development.log

此后一切正常.
