Warning: Calling a Formula#patches definition is deprecated! Use 'patch do' block calls instead.
Please report this issue to the docmunch/pdftk tap (not Homebrew/brew or Homebrew/core), or even better, submit a PR to fix it:
/usr/local/Homebrew/Library/Taps/docmunch/homebrew-pdftk/pdftk.rb:15
Warning: You have the following deprecated, official taps tapped:
Homebrew/homebrew-dupes

Untap them with `brew untap`.
Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and which additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7-config
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7m-config
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3-config

这是PyPy问题跟踪器上issue 3229的副本。看来我们的编译器正在使用libffi的brew install版本。在我们解决此问题之前，您应该可以执行brew install pypy3。欢迎可以使PyPy构建看起来更像CPython（显然没有此问题）的人提供帮助。
