所以我想安装openerp 7.0.406，它需要pychart，而且pip中唯一的链接似乎已经断开。
No distributions at all found for pychart in ./env/lib/python2.7/site-packages (from openerp-core==7.0.406->-r picdyn_openerp_conf/requirements (line 11))
在日志中我们有：

Could not find any downloads that satisfy the requirement pychart in ./env/lib/python2.7/site-packages (from openerp-core==7.0.406->-r picdyn_openerp_conf/requirements (line 15))
当您检查uri时，它返回一个404未找到。所以我从其他地方下载了pychart（http://download.gna.org/pychart/），并尝试安装它（在我的virtualenv中）。
pip install PyChart-1.39.tar.gz
Installing collected packages: PyChart
Running setup.py install for PyChart
Successfully installed PyChart
看起来，它并没有真正工作，因为当我再次尝试从我的需求文件中更新时，pip仍然试图访问带有相同错误消息的“http://www.hpl.hp.com/personal/Yasushi_Saito/pychart”，而openerp无法安装。
但当我试图重新安装PyChart时，它说PyChart实际上已经安装：
pip install PyChart-1.39
Requirement already satisfied (use --upgrade to upgrade): PyChart==1.39 from file:///home/pierre/PyChart-1.39 in ./env/lib/python2.7/site-packages
我做错什么了吗PyChart是否已安装，或者OpenERP的依赖性是否有问题？pychart与pip的pychart不同吗？
最佳答案
您可以尝试，在您的PyChart中将无效的Python-Chart替换为requirements.txt：
蟒蛇图==1.39
对我有用。
