我在Linux Mint 17.3系统中使用pip3安装了

我的系统中似乎缺少与

bootstrap3

相关的内容。这是怎么一回事？我还应该安装什么。

据django-bootstrap3的开发者说，忽略这些警告是安全的：

---

问题#268:安装警告：在目录'bootstrap3'*下找不到与.png'匹配的文件：

renpj:

我在安装过程中收到以下警告：

warning: no files found matching '.png' under directory 'bootstrap3'
warning: no files found matching '.gif' under directory 'bootstrap3'

[...]

我使用的是Django 1.8.2和python 2.7.6

dyve（所有者）：

你可以放心地忽略这些。如果有人知道如何改进sep 我想知道，这样这些警告就不会出现了
