你的 /opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages 目录下有 tornado ？




我which PYTHON 确定我使用的python 是通过PORT安装的PYTHON

Pro:develop uer$ which python
/opt/local/bin/python

python的原身为：/opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6


如果你直接在命令行执行 python 默认是执行的 /usr/bin/python
而 port 安装的 python 是 /opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/python2.6\

同理使用哪个版本安装的 setuptools 在使用 easy_install 的时候
也会把 package 安装到相应的 python 目录去







Mac Port 基本用法总结

1. Mac Port的下载地址

http://www.macports.org/install.php

2. Mac Port的说明文档

http://guide.macports.org/

3. Mac Port中第三方软件下载包存放的默认路径是：/opt/local/var/macports/distfiles/
为了提高安装速度，可以在安装新port时直接将此目录下的文件拷贝到新的Mac Port
相同的目录中就可以避免Port去网上下载。

4. 使用Mac Port前应该首先更新Port的index

$ sudo port selfupdate
Password:
Warning: port definitions are more than two weeks old, consider using selfupdate
—> Updating the ports tree
—> Updating MacPorts base sources using rsync
MacPorts base version 1.9.2 installed,
MacPorts base version 1.9.2 downloaded.
—> MacPorts base is already the latest version

The ports tree has been updated. To upgrade your installed ports, you should run
port upgrade outdated

5. 查看Mac Port中当前可用的软件包及其版本

$ port list
rabbitmq-server @2.4.0 net/rabbitmq-server
AppHack @1.1 aqua/AppHack
AppKiDo @0.985 aqua/AppKiDo
AquaLess @1.6 aqua/AquaLess
ArpSpyX @1.1 aqua/ArpSpyX
AssignmentTrackerX @2.0beta3.1 aqua/AssignmentTrackerX
BigSQL @1.0 aqua/BigSQL
BiggerSQL @1.3.9 aqua/BiggerSQL
Books @3.2.5c aqua/Books
……

4. 在Mac Port如何搜索需要安装的软件包？

$ port search maven
maven @1.0.2 (java, devel)
A java-based build and project management environment.

maven-ant-tasks @2.0.10 (devel, java)
Use many of Maven’s artifact handling features from Ant.

maven2 @2.2.1 (java, devel)
A java-based build and project management environment.

maven3 @3.0.3 (java, devel)
A java-based build and project management environment.

maven_select @0.3 (sysutils)
Switch the default Maven java build tool

Found 5 ports.

5. 搜索到需要安装的软件包之后，如何查看具体的软件包的内容和说明？

$ port info maven2
maven2 @2.2.1, Revision 3 (java, devel)

Description: Maven is a Java project management and project comprehension tool. Maven is based on the concept of a
project object model (POM) in that all the artifacts produced by Maven are a result of consulting a
well defined model for your project.Builds, documentation, source metrics, and source cross-references
are all controlled by your POM. Maven 2.0 is a complete rewrite of Maven 1.0 and as such is better
organized, faster and easier to use.

Build Dependencies: kaffe
Library Dependencies: maven_select
Platforms: darwin
License: unknown
Maintainers: blair@macports.org, gk5885@kickstyle.net

6. 查看即将安装的或者已经安装的软件包的依赖关系

$ port deps maven2
Full Name: maven2 @2.2.1_3
Build Dependencies: kaffe
Library Dependencies: maven_select

7. 查看安装时允许客户定制的参数

$ port variants maven2
maven2 has no variants

8. 查看了软件包的内容和说明，并确认确实要安装，则

$ sudo port install maven2

9. 安装完毕之后，清除安装时产生的临时文件

$ sudo port clean –all maven2
—> Cleaning maven2

10. 卸载已经用Mac Port安装的软件

sudo port uninstall maven2
