安装pandas包时出错：没有名为numpy的模块

时间：2014-03-20 15:16:07

标签： python numpy pandas

我有一个包含多个项目的大解决方案。我使用virtualenv。 因此，对于我在解决方案中的一个项目，我已经安装了我需要的东西，包括numpy和pandas

但当我执行类似的事情时：

cd ../project2
sudo python setup.py develop

无法安装pandas包并显示错误

ImportError: no module named numpy

但如果我在

后立即运行类似的东西 
python
import numpy
numpy.version.version
import pandas
pandas.version.version

它绝对正确地解析了这段代码，并向我展示了已安装软件包的版本。

那么问题是什么，如何解决它以便能够安装项目依赖项？

从python -msite的输出中可以看出，python和sudo python在非常不同的环境中运行Python版本。他们看到不同的模块并不奇怪。 sudo通常会更改您的环境，尤其是您的PATH和HOME环境变量，这可能会导致运行不同的PYTHON解释器，或者导入不同的user模块

通常，在主目录中的virtualenv中安装内容时，没有理由要使用sudo。您应该使用virtualenv中的pip安装来安装软件包。

我最近在尝试将熊猫从0.23.1版本更新到0.24.1时遇到此错误。

解决我问题的方法是先执行以下命令来更新点子：

python -m pip install --upgrade pip

然后更新所需的库。
