升级ML后,python的开发环境悲剧了。

    这是一个创建于 4507 天前的主题,其中的信息可能已经有所发展或是发生改变。
    (︸_︸) 不知道哪里出了问题。

    以前好不容易才搭好的,最近用着特顺手,结果升级之后发现少了好多东西?(本来只剩5G空间的,升级之后变成了50多G)。mysql之类的好在,但是web.py、mysqldb什么的都需要重新装。/library/python/2.7/site-packages里空空如也。

    LZ正在苦逼的装包中。

    Ruby的情况是有些需要gcc的因为gcc丢失出错了,Xcode把command line tool装上然后重新link一下就好了。或许你的一些情况类似这个?

    正经的说, 开虚拟机用linux做, 坏了大不了重开一个, 自己的系统折腾起来挺麻烦的。

    @pepsin 新系统似乎是不用GCC,改用Clang了,本来我正在研究怎么装Clang,但是看了你的恢复之后决定先装上command line tool,但是不知道你说的Link一下是指什么?还请详细赐教。
    @nichan 额..我也知道在虚拟机里开发是最合适的,但是还是习惯在mac里做。。。感觉每次都要开虚拟机好麻烦。。

    补记一下后续:

    command line tool装上之后,用easy_install安装mysql-python:

    $ sudo easy_install mysql-python

    Adding MySQL-python 1.2.3 to easy-install.pth file

    Installed /Library/Python/2.7/site-packages/MySQL_python-1.2.3-py2.7-macosx-10.8-intel.egg
    Processing dependencies for mysql-python
    Finished processing dependencies for mysql-python

    虽然有一些奇怪的东西出现,但好歹装上了。

    接着去web.py下运行project试试能不能启动:

    $ python application.py
    Traceback (most recent call last):
    File "application.py", line 13, in <module>
    import config
    File "/Users/hanjiyun/Project/sputnik/config.py", line 10, in <module>

    File "build/bdist.macosx-10.8-intel/egg/_mysql.py", line 6, in __bootstrap__
    ImportError: dlopen(/Users/hanjiyun/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.8-intel.egg-tmp/_mysql.so, 2): Library not loaded: libmysqlclient.18.dylib
    Referenced from: /Users/hanjiyun/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.8-intel.egg-tmp/_mysql.so
    Reason: image not found

    悲剧,后来在 http://yan-yan.info/2011/install-mysql-5.5-on-mac-os-10.7-with-python-support.html 找到办法:

    在/etc的profile文件中加入一行
    export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/usr/local/mysql/lib"

    然后重启电脑。

    再次运行项目,发现无法与Mysql连接,我这才想起来mysql还没启动,我的mysql版本是mysql-5.5.25-osx10.6-x86_64,需要通过“系统偏好设置” 中的MySQL面板来启动。



    但是启动的时候发现报错:

    Warning: The /usr/local/mysql/data directory is not owned by the 'mysql' or '_mysql' user

    在stackoverflow找到解决办法:
    http://stackoverflow.com/questions/4762543/mysql-what-user-should-own-usr-local-mysql-on-mac

    按照帖子中说的,运行命令:
    sudo chown -R _mysql:wheel /usr/local/mysql/data
    Mysql顺利启动。

    再次运行项目:
    $ python application.py
    http://0.0.0.0:8080/


    终于搞定了。


    绳命在于折腾。

    刚又有新发现。

    上面提到
    ————
    在/etc的profile文件中加入一行
    export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/usr/local/mysql/lib"
    ————

    刚才在运行nginx是发现有点小问题:

    $ sudo nginx
    dyld: DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid

    多了一行提示,但是没什么影响。

    似乎是profile中的那行DYLD_LIBRARY_PATH的原因,我现在注释掉了,明天重新开机后看看会有什么情况。

    @paloalto 别用环境变量了,直接
    sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib 做个软连接就行了

    开发这个玩意,我建议是用 home brew 了, 大部分软件都是新的,而且 prefix 是 /usr/local

    ,这样升级系统也就是 改下 PATH就可以了。
    我从 lion 升到 ml 就没太多问题
