如何在Mac上使用PyPy？

Question

PyPy的速度承諾讓我想嘗試一下。 不幸的是，我在這個主題上閱讀的教程都沒有真正幫助我理解基礎知識，即如何（簡單的步驟）：

• 在Mac上安裝PyPy
• 運行.py腳本

我讀到從bin/中下載，提取和運行pypy myscript.py應該可以做到這一點，但到目前為止我沒有運氣。 這是我得到的：

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

任何人都可以幫我理解PyPy的基本用法嗎？

Answer 1

你嘗試過使用自制軟件（ http://brew.sh/ ）嗎？

~ $ brew search pypy
pypy

看起來像“釀造安裝pypy”應該讓你到那里。

~ $ 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

編輯：或者您是否已檢查是否已將安裝放在路徑上？ 例如，我抓住它並將其放入我的主目錄。

~ $ 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中我將以下行放入：

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

現在我可以從任何地方運行pypy~ / scripts / test.py。

----編輯2 ----回答有關丟失包裹的最后一個問題：

“如果你想安裝第三方庫，最方便的方法是安裝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

“第三方庫將安裝在pypy-2.1 / site-packages中，而腳本將安裝在pypy-2.1 / bin中”
