如何在Mac上使用PyPy？

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

我读了下载,解压并运行pypy myscript.py从bin/应该做的伎俩,但没有运气,我至今.这是我得到的:

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

任何人都可以帮我理解PyPy的基本用法吗？

Answer 1

你尝试过使用自制软件(http://brew.sh/)吗？

~ $ brew search pypy
pypy

看起来像"酿造安装pypy"应该让你到那里.

~ $ brew versions pypy

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 ----回答有关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,而脚本将安装在pypy-2.1/bin中"
