在heroku上部署matplotlib失败。如何正确操作？

Question

我用pip在我的virtualenv中安装了matplotlib。一开始是个失败，但是在我完成easy_install -U distribute之后，安装就顺利进行了。在

以下是我要做的（在git存储库根文件夹中）：

virtualenv env
source env/bin/activate
pip install gunicorn
pip install numpy
easy_install -U distribute
pip install matplotlib

然后，我做一个要求.txt通过使用pip freeze > requirements.txt。结果如下：

^{pr2}$

尝试部署应用程序时出现问题：

heroku服务器似乎无法正确安装matplotlib。在

当我这样做时，easy_install -U distribute它可能没有被pip记录。在

Matplotlib还有几个非python库依赖项（例如：libjpeg8 dev、libfreetype和libpng6 dev）。我可以在本地安装这些依赖项（例如：通过apt-get）。然而，这也没有被pip记录。在

所以，我的问题是：如何在heroku部署服务器中正确安装matplotlib？在

Answer 1

我在使用matplotlib和{}时也有困难，答案很难找到。This帮了我。在

基本上你要做的就是push the project with numpy在requirements.txt中。只有在这之后，我们必须add pandas and matplotlib到{}。在
