在XP中源码运行OpenERP70全过程记录

[保定-粉刷匠]

                    在XP中源码运行OpenERP70全过程记录
1）用easy_install安装lxml时，要指定版本为2.2.2，即用命令“easy_install lxml==2.2.2”
2)用easy_install安装好PIL后，在python中要执行“import Image”命令，而不是“import PIL”，另外源码image.py中去掉“import Image”前的“from PIL”
3）提示缺少yaml时，使用“easy_install pyyaml”。
4）提示缺少reportlab.platypus时，使用“easy_install pyyaml”
5)用easy_install安装reportlab时，提示下载文件与MD5不符，采用直接下载Windows安装文件解决，地址：http://pypi.python.org/packages/2.6/r/reportlab/reportlab-2.5.win32-py2.6.exe。
6)用easy_install安装pychart时，提示下载地址错误，从此处下载并用"python setup.py install".
7)提示缺少workzeug.serving时，使用“easy_install pyyaml”,从此处下载，并用"python setup.py install".
8）去掉了workers.py中的“import resource”
9）提示缺少Openid时，安装“python-openid”
10）提示缺少docultils-core时，安装“docultils”
11)提示缺少“google”模块时，安装gdata，从此处下载，并用"python setup.py install".
此时OpenERP的Server服务启动成功，从火狐能进入登录界面。
但不能创建数据库。

望高手解决上述问题，否则无法继续测试！

我没研究过新版的系统，看似问题不少。
表面上看，这个异常是在获取客户某些缩略图引起的。

<br />image = Image.open(image_stream)<br />

这句，Image对象只接受infile (name or stream obj). 不会接受一个base64编码的string.
从上面的代码看，其实系统是从数据库里拿出了数据，base64 encode以后，交给PIL的。

要想PIL从base64 string读取图片，则需要:

<br />from PIL import Image<br />from base64 import decodestring<br /><br />image = Image.fromstring(&#039;RGB&#039;,(width,height),decodestring(imagestr))<br />image.save(&quot;foo.png&quot;)<br /><br />

仅供参考。

OE 仅支持 PIL >= 1.1.7  版本,安装此版本后应该可以解决PIL报错问题。
