我已经使用 pip 在我的 virtualenv 中安装了 matplotlib。一开始是失败的,但是在我这样做之后easy_install -U distribute
,安装就很顺利了。
这是我所做的(在我的 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,我使用 .txt 制作了一个 requirements.txt pip freeze > requirements.txt
。结果如下:
argparse==1.2.1
distribute==0.7.3
gunicorn==17.5
matplotlib==1.3.0
nose==1.3.0
numpy==1.7.1
pyparsing==2.0.1
python-dateutil==2.1
six==1.3.0
tornado==3.1
wsgiref==0.1.2
当我尝试部署我的应用程序时发生了问题:

似乎 heroku 服务器无法正确安装 matplotlib。
当我这样做时easy_install -U distribute
,它可能不会被 pip 记录。
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
)。但是,这也没有被 pip 记录。
所以,我的问题是:如何在 heroku 部署服务器中正确安装 matplotlib?
