Rails新应用由于权限而失败

Question

I've searched for some time now but can't solve the problem. I'm on a relatively new computer (osx), only created one rails app on it so far. Until now everything went well. I'm now trying to create a new app using

rails new appname

This is what the terminal shows me:

Installing tilt (1.4.1) 
Errno::EACCES: Permission denied - /Library/Ruby/Gems/1.8/build_info/tilt-1.4.1.info
An error occurred while installing tilt (1.4.1), and Bundler cannot continue.
Make sure that `gem install tilt -v '1.4.1'` succeeds before bundling.

When I enter

gem install tilt -v '1.4.1'

I get the following:

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/1.8 directory.

While searching I've found people with similar looking errors but I couldn't find anything solving my specific problem.

I'm using ruby 2.0.0 and rails 2.3.13.

I really stuck and hope someone knows how to fix this. Thanks in advance!

Update: I noticed, when I run the rails new app command, the terminal asks me

Enter your password to install the bundled RubyGems to your system: 

It has never done this before. Is it possible that I kind of have changed something on the system?

Update2: After using 2+ days on this, as far as I can say, the solution was to completely reinstall the latest versions of ruby and rails.

Answer 1

尝试sudo或在您可以访问的目录中创建您的应用

Answer 2

尝试sudo gem install tilt -v '1.4.1'

Answer 3

If the sudo "gem install tilt -v '1.4.1'" doesn't work. Then most likeley, the group "others" don't have correct permissions in your Ruby innstall. Make sure, you give correct permissions for group=others or users running the command in your:

/Library/Ruby/Gems/1.8
