我正在运行一个程序来自另一个不便的人请求帮助.该计划是一个网站.服务器端由python和flask(模块,http://flask.pocoo.org/)编写.该程序已在服务器上成功运行.我需要做的是修改它上面的东西.由于生产服务器不允许进行测试,因此我通过flask在本地开发服务器中对其进行了测试.但是,我甚至无法运行原始程序.下面是python.

$ sudo apt-get install python-virtualenv
然后通过建立一个环境
$ mkdir myproject
$ cd myproject
$ virtualenv venv
New python executable in venv/bin/python
Installing distribute............done.
激活它
$ . venv/bin/activate
在环境中安装了python-numpy
$ sudo apt-get install python-numpy
但是,我尝试在完成上述所有步骤后在环境中导入python中的numpy.Python告诉我"没有名为numpy的模块".然而,numpy可以在全球范围内导入Python.我试图删除和安装很多次,但它不起作用.我是Python和Linux的初学者.
