python - python TypeError:必须是不带NULL字节的编码字符串，而不是str-docker iron requirements.txt

Question

我一直在尝试将Python脚本部署到Iron.io。他们建议在上传之前使用docker在本地进行测试。

我已经完成their provided docker/iron tutorial，没有错误。

因此，我开始从其示例存储库中修改the provided requirements.txt以启动自己的项目，但是每当我尝试在本地安装软件包时，都会收到TypeError。

我的点是版本:

pip 7.1.2 from /Library/Python/2.7/site-packages (python 2.7)

他们的要求

iron-mq>=0.5
iron-worker>=1.3.1

我的requirements.txt

iron-mq>=0.5
iron-worker>=1.3.1
beautifulsoup4
html5lib

终端命令:

$ docker run --rm -v "$PWD":/worker -w /worker iron/python:2-dev pip install -t packages -r requirements.txt

错误:

Exception:

  File "/usr/lib/python2.7/site-packages/pip/basecommand.py", line 211, in main
    status = self.run(options, args)

 File "/usr/lib/python2.7/genericpath.py", line 49, in isdir
    st = os.stat(s)
 TypeError: must be encoded string without NULL bytes, not str

我在OSX上使用Sublime，并使用UTF-8编码。通常，通过转义某些字符或更改编码来解决与该错误有关的其他线程。但是我找不到使用的替代编码。

有没有技巧可以保存没有空字节的需求？还是有另一个已知的解决方法？

编辑更新:

使用-vvv max详细模式运行pip

docker run --rm -v "$PWD":/worker -w /worker iron/python:2-dev pip install -vvv -t packages -r requirements.txt

唯一的新输出是底部的两行。

运行iconv以识别任何流氓字符只会返回txt文件的内容。

iconv -t UTF-8 requirements.txt

iron-mq>=0.5
iron-worker>=1.3.1
beautifulsoup4==4.4.1

尝试使用Iron docker镜像在Mac上运行pip install时遇到了同样的麻烦。在尝试了许多修复方法后，我将问题归结为Docker Toolbox和vboxfs。他们没有正确同步主机文件系统更改。要修复它，我在docker工具箱VM中运行:
sync; echo 3 > /proc/sys/vm/drop_cachessync调用将所有未完成的写入同步到磁盘。第二条命令告诉内核清除文件系统缓存。

一旦我做到了，我的pip install可以正常工作。
