python - 运行 edX 开发者堆栈 : Error on running paver lms

Question

我正在按照 edx 教程运行 devstack(来自 http://edx-installing-configuring-and-running.readthedocs.org/en/latest/devstack/run_devstack.html#default-accounts-on-devstack )，我在运行命令“paver lms”时遇到错误。

错误如下:

edxapp@precise64:~/edx-platform$ paver devstack lms

---> pavelib.prereqs.install_prereqs

python manage.py lms --settings=devstack preprocess_assets
Traceback (most recent call last):

python manage.py lms --settings=devstack preprocess_assets

Build failed running pavelib.servers.devstack: Subprocess return code: 1

请指导我运行该命令需要做什么。

Answer 1

你必须跑

paver install_prereqs
paver update_assets lms --settings=devstack
paver update_assets studio/cms --settings=devstack

否则手动安装要求

将以下内容添加到文件requirements/edx/local.txt并重新运行上述命令

-e common/lib/capa
-e common/lib/chem
-e common/lib/dogstats
-e common/lib/safe_lxml
-e common/lib/sandbox-packages
-e common/lib/symmath
-e common/lib/xmodule

请引用paver
