Heroku：没有 NULL 字节的字符串，有几个需求文件

Question

我正在尝试按照 "Two scoops of Django 1.6" 项目结构从 Ubuntu 在 Heroku 中部署 Django 网络应用程序。

完成 heroku create 后，我运行 git push heroku master 并附上输出最后。

我在谷歌上进行了大量搜索，我知道错误是这样的

TypeError: must be encoded string without NULL bytes, not str

是由于需求文件中的一些编码或稀有字符引起的。我的问题是，我尝试以较少的依赖项保存并更改文件中的编码，但没有取得任何成果（我不知道 Heroku 的有效编码，所以我对此视而不见）。

我正在寻找一种查找空字符的方法，即使在命令行中使用 cat -e，但我找不到任何东西。 我正在寻求一种查找编码问题或错误依赖项的方法。

先谢谢你。

编辑： 我试过 pip

install -r <fileName>.txt

我的几个需求 txt 文件。所有的安装都很好。我还尝试执行 git push heroku master，所有内容都在主 requirements.txt（一个空文件）中进行了注释，但它一直出现相同的错误。也许 heroku 没有选择 requirements.txt 文件？？？

我尝试从命令行重新创建文件并手动输入相同的内容（不是复制粘贴）。同样的错误不断出现。 :-(

文件和输出：

我的需求文件是：

requirements.txt（在项目的最根部）：

# This file is here because many Platforms as a Service look for
# requirements.txt in the root directory of a project.
-r requirements/production.txt

requirements/production.txt:

# Pro-tip: Try not to put anything here. There should be no dependency in
# production that isn't in development.
-r base.txt

gunicorn==18.0

和requirements/base.txt:

Django==1.7
psycopg2==2.6
sqlparse==0.1.15
django-debug-toolbar==1.3.0
html5lib==0.999
Pillow==2.8.1
PyPDF2==1.24
reportlab==3.1.44
six==1.9.0
xhtml2pdf==0.0.6

Answer 1

都是我的错。超级新手愚蠢的错误。我没有在每次编辑后进行 git 提交，所以我总是将相同的错误文件推送到 Heroku。

现在终于明白了，push的时候报错又改了

非常感谢您的帮助，很抱歉让您耽误了时间。
