Python公文包Django：设置.py返回非零退出状态1

Question

• Ubuntu 18.04 LTS
• Python 3.6
• 节点8.11.4（LTS）
• 净现值5.6.0

尝试按照公文包教程中的instructions安装教程django项目。它可以很好地安装Linux文件，但是尝试以相同的方式安装它，但是使用djangopython3 setup.py django -s会导致以下失败：

我尝试过四处搜索，甚至直接用pip install --upgrade --force-reinstall --no-dependencies --target=/home/hv/Projects/tutorial/helloworld/django .运行pip命令，其输出：

^{pr2}$

我对这件事很陌生，正在寻求一些建议。这是在virtualenv中的版本： pip 18.0 from /home/hv/Projects/tutorial/venv/lib/python3.6/site-packages/pip (python 3.6)

更新： 删除了对toga-django==0.3.0.dev9的特定要求设置.py文件，并且它似乎已成功安装。但是，它不能实际启动Django服务器： python设置.pydjango-s-v型
