Key points for creating Rails Applications in China (in windows 7, Rails 4.2.0) and rails4.2.0

 

1. the application created using the rails new command will not succeed when the bundle install is automatically executed. Based on the error prompt, it is determined that the cause may be the security problem of the wall and https certificate. as a development environment, you can create a gemrc file in the directory C: \ ProgramData with only one line of code in it:

: Ssl_verify_mode: 0

2. Run the command gem sources-a http://gems.ruby-china.org to add the ruby-china gem source to the system source.

3. run the gem sources command to display the list of configured System sources, and then delete other invalid gem sources, such as "gem sources-r https://rubygems.org/", in sequence using the gem sources-r URL /"

4. run the command bundle install -- retry 10 in the directory of the rails application to install and update gems. the reason for setting retry times is that the gem service cloud storage server where ruby-china is located is not stable currently. You need to execute bundle install repeatedly to install it successfully.

 

For the solution, refer to the website information in the error prompt, which is not listed here.
