ImportError：没有名为“ pandas”的模块（在virtualenv内部）

Question

我为python创建了一个名为quora的虚拟环境。我安装了车轮，然后按照指示安装了熊猫。由于某种原因，我无法让熊猫上班。有人能帮我吗。我已经尝试了该网站上针对类似问题的所有其他解决方案。还是没用。

(quora) (jessie)griffith@localhost:~/environments$ sudo pip install wheel
Requirement already satisfied: wheel in /usr/lib/python2.7/dist-packages
(quora) (jessie)griffith@localhost:~/environments$ sudo pip install pandas

不要在virtualenv中使用sudo-sudo pip install将软件包安装到global中site-packages，而不是在virtualenv中。

（pip install在激活venv之后）在虚拟环境中安装熊猫或启用对全局软件包的访问（使用option重新创建venv--system-site- packages或使用toggleglobalsitepackagesvirtualenvwrapper中的命令）。
