Previous versions used homebrew to install the various versions. As suggested in the comments, it's better to use pyenv instead. If you are looking for the previous version of this document, see the revision history.

$ brew update
$ brew install pyenv
$ pyenv install 3.5.0
$ pyenv install 3.4.3
$ pyenv install 3.3.6
$ pyenv install 3.2.6

Haul, a purely functional package manager for Rust



  • Purely functional
    • Different versions of packages can coexist
    • Each package must have a UUID, so packages with conflicting names can coexist
  • Build logic
    • Each package's metadata and build logic is written in a central Rust source file,
    • Dependencies are declared in the package file and will be fetched and installed before

unshimmable subset of ES5

The following features of ES5 cannot be shimmed.

The ones you care about

Enumerable properties [ES3]

Using Object.defineProperty if you define a non-enumerable property on an object then loops over that object will behave correctly in modern browsers but enumerate over that property in legacy browsers.

This means that code that works in modern browsers, breaks in legacy browsers.

You can’t perform that action at this time.
