Question

PyPy的速度承诺让我想尝试一下。不幸的是，我在这个主题上阅读的教程都没有真正帮助我理解基础知识，即如何（简单的步骤）：

在Mac上安装PyPy
运行.py脚本

我读到从pypy myscript.py下载，提取和运行bin/应该可以解决这个问题，但到目前为止我没有运气。这是我得到的：

MyMacbook:bin User$ pypy myscript.py
-bash: pypy: command not found

有人能帮我理解PyPy的基本用法吗？

您是否尝试过使用自制程序（http://brew.sh/）？

~ $ brew search pypy
pypy

看起来像“brew install pypy”应该可以帮助你。

~ $ brew versions pypy

1.3      git checkout a546a1f /usr/local/Library/Formula/pypy.rb
1.2      git checkout 89de8bb /usr/local/Library/Formula/pypy.rb

编辑：或者，您是否已检查是否已将安装放在路径上？例如，我抓住它并将其放入我的主目录。

~ $ ll ~/ | grep pypy
drwxr-xr-x@  9 squiddly  staff    306 Nov 27 07:42 pypy-2.2.1-osx64

然后在我的.bash_profile中我将以下行放入：

# Put pypy on my path
PATH=$PATH:$HOME/pypy-2.2.1-osx64/bin
export PATH

现在我可以从任何地方运行pypy~ / scripts / test.py。

----编辑2 ---- 要回答关于丢失包裹的最后一个问题：

“如果你想安装第三方库，最方便的方法是安装distribute和pip：”

$ curl -O http://python-distribute.org/distribute_setup.py
$ curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py
$ ./pypy-2.1/bin/pypy distribute_setup.py
$ ./pypy-2.1/bin/pypy get-pip.py
$ ./pypy-2.1/bin/pip install pygments  # for example

“第三方库将安装在pypy-2.1 / site-packages中，脚本安装在pypy-2.1 / bin”
