Python 导入错误 : No module named webpack_loader

Question

我曾尝试查看类似的问题，但确实很难找到解决此问题的方法。我知道会有一些 super 聪明的软件工程师比我有更好的想法!

我有一个用 django 后端在 react.js 中构建的单页网站。

它可以在我的电脑上运行，但当我试图将它加载到服务器 (PythonAnywhere) 时就无法运行。真的很沮丧，因为我真的很期待在线发布它。

我收到的错误如下:

Unhandled exception in thread started by <function wrapper at 0x7f67f8b4cb90>

Traceback (most recent call last):

  File "/usr/local/lib/python2.7/dist-packages/django/utils/autoreload.py", line 226, in wrapper

    app_config = AppConfig.create(entry)

  File "/usr/local/lib/python2.7/dist-packages/django/apps/config.py", line 90, in create
    module = import_module(entry)

  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)

ImportError: No module named webpack_loader

我已经看过明确init.py 代码的编码，我认为这可能与下面的 settings.py static_root 和 webpack_loader 设置有关。

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

STATIC_URL = '/static/'

STATIC_ROOT = os.path.normpath(os.path.join(BASE_DIR, 'djreact/static/root'))

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'djreact/static'),
]

WEBPACK_LOADER = {
    'DEFAULT': {
        'BUNDLE_DIR_NAME': 'bundles/local/',  # end with slash
        'STATS_FILE': os.path.join(BASE_DIR, 'webpack-stats-local.json'),
    }
}

我遵循了下面给出的建议，但现在收到此错误。我认为这是由于我没有使用虚拟环境但不确定。解决一个问题，另一个问题就会出现!

提前致谢 - 我是一个十足的新手，但我正在尽可能快地学习!

这是因为你还没有安装模块django-webpack-loader。

只需使用:

pip install django-webpack-loader
