我正在关注these instructions在mac上安装odoo。它要求我为用户安装所有python模块，如下所示：
$ sudo pip install -—user -r requirements.txt
（* note关于--user部分）
然而，当我运行odoo时，我收到此错误：
$ ./odoo-bin
Traceback (most recent call last):
File "./odoo-bin", line 5, in <module>

ImportError: No module named reportlab.lib
我注意到这个reportlab可以在requirements.txt中找到：
reportlab==3.3.0
但是，如果我运行此命令
pip freeze | grep reportlab
我什么都没得到，但是当我运行这个命令时
sudo pip install --user reportlab
我得到以下内容：
$ sudo pip install --user reportlab

我已按照建议here尝试重新安装，但这并没有做太多。
想法？
