Question

当我激活虚拟环境以使用conda并从终端写“conda list”以查看我安装的所有软件包时，我收到以下消息：

[pandas_env] C:\Users\michele.dellamea\Desktop\boms_sent>conda list
# packages in environment at C:\Users\michele.dellamea\AppData\Local\Continuum\A
naconda3\envs\pandas_env:

env\Scripts\pip-script.py", line 5, in <module>
    sys.exit(pip.main())
AttributeError: module 'pip' has no attribute 'main'
An unexpected error has occurred, please consider sending the
following traceback to the conda GitHub issue tracker at:

Include the output of the command 'conda info' in your report.

当我写“conda info”时：

[pandas_env] C:\Users\michele.dellamea>conda info
Using Anaconda Cloud api site https://api.anaconda.org

          config file : None

奇怪的是，我记得一个月前命令“conda list”成功运作，但知道事情发生了变化。

Answer 1

我遇到了这个问题，解决方法很简单，只需将安装目录更改为C：\ Anaconda3，或者某个不包含点或特殊字符和空格的文件夹。

示例：

C:\Anaconda3
C:\Users\Anaconda3

请注意，在您自己的某个目录（您的用户文件夹）中安装Anaconda需要授予管理员权限。

将Anaconda3重新分配到C：\ Anaconda3之后，所有工作都按预期进行。

Answer 2

检查https://github.com/conda/conda/issues/8156。尝试删除C：\ Anaconda3 \ Lib \ site-packages \ Sphinx-1.3.1-py3.4.egg \ EGG-INFO文件
