我正在关注these instructions以在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

（* 关于--user部分的说明）
但是，当我运行Odoo时，我得到这个错误：

./odoo-bin

输出：

Traceback (most recent call last):
  File "./odoo-bin", line 5, in <module>
    __import__('pkg_resources').declare_namespace('odoo.addons')
  File "/Library/Python/2.7/site-packages/setuptools-36.5.0-py2.7.egg/pkg_resources/__init__.py", line 2241, in declare_namespace

    from .simple import simple
  File "/opt/odoo/odoo-10.0/odoo/report/render/simple.py", line 8, in <module>
    import reportlab.lib
ImportError: No module named reportlab.lib

我注意到这个报告实验室在 requirements.txt 中可用：

reportlab==3.3.0

但是，如果我运行这个命令

pip freeze | grep reportlab

我什么也得不到，而且当我运行这个命令时

sudo pip install --user reportlab

我得到以下结果：

sudo pip install --user reportlab

输出：

我已经尝试强制重新安装建议here，但没有做太多。
我该怎么解决这个问题？
