一直對 RVM 的 shell-hacking 行為很感冒也很困擾, 但是沒有了她又勢必崩潰在如滿天星斗的 Ruby 版本中…
決定從 RVM 轉到 rbenv (早該這麼做了). 先不管 rbenv 有什麼吸引人的 feature, 至少對比起 RVM 少了一些 dirty (IMO) hacks:
- RVM Need to be loaded into your shell. Instead, rbenv’s shim approach works by adding a directory to your
$PATH. (這點超討厭!) - RVM Override shell commands like cd or require prompt hacks. That’s dangerous and error-prone.
- RVM Have a configuration file. There’s nothing to configure except which version of Ruby you want to use.
- RVM Install Ruby. You can build and install Ruby yourself, or use ruby-build to automate the process. (這個也很煩, Ruby binaries 我想自己管理就好, RVM 似乎有點撈過界…)
- RVM Manage gemsets. Bundler is a better way to manage application dependencies. If you have projects that are not yet using Bundler you can install the rbenv-gemset plugin. (管理 gemsets 這種事還是交給專業的來吧…)
- RVM Require changes to Ruby libraries for compatibility. The simplicity of rbenv means as long as it’s in your
$PATH, nothing else needs to know about it.
說了這麼多好像都是在批 RVM, 不過嘛… 工具這種東西就是這樣, 一定是越來越進步. 如同沒有 CVS, SVN 的難用, 就不會有好用的 Git 誕生一樣, 還是謝謝 RVM 陪伴了多年的時光, 功成身退.
