Use bundler path option

[kenchan]

There was a problem occurs when you bundle update multiple projects (gems installing Git or Github repositories) simultaneously.

In summary, Bundler locked .git directory while upgrading a gem.(The root cause is a problem that occurs when the Bundler is parallel execution. 😢)

• pros
  • independence
• cons
  • speed
  • disk usage

how do you think?

Independence is important!:muscle:

The issue:
When bundler updates gem(via git), at first checkout gem, then copy gem, so this checkout from multiple projects at the same time breaks bundle update.
