ModuleNotFoundError：conda 中没有名为“__builtin__”的模块

Question

我查看了其他答案，例如 conda install future 和其他答案，但似乎没有一个可以解决此错误。直到昨天一切正常，但今天当我尝试运行我的脚本时，我收到了这个错误。

我最初认为我有多个来自 pip 和 conda 的 pandas 包，所以我从这两个包中卸载，然后再次通过 conda 安装。但错误仍然存​​在。

我已经在 anaconda 2 中安装了 python 3.6 作为单独的环境。

Traceback (most recent call last):
  File "/Users/amit/anaconda2/envs/python36/lib/python3.6/site-packages/pandas/compat/__init__.py", line 49, in <module>
    import __builtin__ as builtins
ModuleNotFoundError: No module named '__builtin__'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "main.py", line 18, in <module>
    from nameserver import NameServer
  File "/Users/amit/Work/ml/marl/nameserver.py", line 4, in <module>
    import pandas as pd

    import http.client as httplib

按照@EvgenyPogrebnyak 的建议，我创建了一个名为py36 的新环境。我尝试从主目录运行 print 语句 python -c "import pandas as pd; print(pd.__version__)" 语句，或者实际上它运行正常的任何其他目录，但是当我从我的项目目录运行它时，我得到了这个特殊的错误，这很奇怪。

amit:~ $source activate py36
(py36) amit:~ $python -c "import pandas as pd; print(pd.__version__)"
0.23.0
(py36) amit:~ $cd Work/ml/marl/
(py36) amit:~/Work/ml/marl $python -c "import pandas as pd; print(pd.__version__)"

我认为下面的代码应该运行。退出环境是你在跑步之前合而为一。

conda create -n new1 python=3.6 pandas
source activate new1
python --version
# expected:
# Python 3.6.0 :: Anaconda 4.3.0 (32-bit)
python -c "import pandas as pd; print(pd.__version__)"
# expected '0.22.0',but more importantly this shows pandas in imported

这会运行吗？您可以使用conda install -n new1 <package> 安装更多库，然后尝试：

python /Users/amit/Work/ml/marl/nameserver.py

pipenv 可以达到类似的结果。
