Question

我是编程新手，所以遇到了这个麻烦。我已经升级了点子，然后使用点子列表，ipython笔记本，jupyter笔记本来使用anaconda，所以在完成所有这些命令后，我得到了一个答案：

请问您能帮我解决这个问题吗？十分感谢。我在用着： -Ubuntu 16.04。（64位） -Python 2.7.12 -Python 3.6.0 :: Anaconda 4.3.1（64位）

P.S：我尝试使用dotenv进行修复，请确保pip（这使我得到答案是我没有此软件包）。

Answer 1

不是一个完整的答案，因为我无法告诉您为什么会发生这种情况，但是希望这可以帮助您找到解决方案。

我曾经遇到过这个问题。当我从头开始尝试构建rjsmin时，一切顺利，那是当我注意到原因是失败的venv使用的是Python 3.6，而新的venv使用的是Python 3.7。

根据您的控制台输出，您正在使用3.6的anaconda，我认为您可能已通过使用pip手动升级软件包来破坏安装。您可以尝试获取较新版本的anaconda，或进行全新安装。

AttributeError：模块“ importlib._bootstrap”没有属性“ SourceFileLoader”
