AttributeError:模块“importlib.\u bootstrap”没有属性“SourceFileLoader”

Question

我不熟悉编程，所以遇到了这个麻烦。 我已经升级了我的pip，然后使用pip list、ipython notebook、jupyter notebook来使用anaconda，所以在所有这些命令之后，我得到了一个答案：

你能帮我解决这个问题吗？非常感谢你。 Im使用： -Ubuntu 16.04。（64位） -Python 2.7.12版 -Python 3.6.0:：Anaconda 4.3.1（64位）

附言：我试着用dotenv修复，ensurepip（这让我得到的答案是我没有这个软件包）。在

不是一个完整的答案，因为我不能告诉你为什么会发生这种情况，但希望这能帮助你找到解决办法。在

我遇到了这个问题。当我从头开始尝试构建rjsmin时，一切都进行得很顺利，也就是我注意到原因是失败的venv使用的是python3.6，而新的venv使用的是python3.7。在

根据您的控制台输出，anaconda使用的是3.6版本，我认为您可能已经通过使用pip手动升级包来破坏您的安装。你可以尝试得到新版本的Python，或去一个新的，新的安装。在
