condaenv和python包

Question

我是康达的新手，我对它的工作原理只有非常肤浅的理解。 我的目标是使用conda安装一个注释软件（dammit）。 康达的安装方式如下：

wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh -O miniconda.sh && bash miniconda.sh -b -p $HOME/miniconda 
echo 'export PATH="$HOME/miniconda/bin:$PATH"' >> $HOME/.bashrc

然后，我创建了一个环境，设置了频道，并安装了我的软件：

conda create -n dammit python=3 
source activate dammit

conda config --add channels defaults 
conda config --add channels conda-forge 
conda config --add channels bioconda 

conda install dammit

当我试图运行主脚本时，出现了一个错误

Traceback (most recent call last):

    AnyStr = TypeVar('AnyStr', bytes, unicode)

问题似乎出在Python2.7libs中的类型包中。我已经在dammit环境中安装了typing.py和conda，但是发生了相同的错误。如何解决这个问题，并使用“import命令”在dammit/lib/python库中搜索

以下是sys.path：

['', '/opt/python', '/opt/lib64/python2.7/site-packages', '/opt/lib/python2.7/site-packages', '/opt/lib64/python3.7/site-packages', '/opt/lib/python3.7/site-packages', '/home/up201505534', '/home/up201505534/miniconda/envs/dammit/lib/python36.zip', '/home/up201505534/miniconda/envs/dammit/lib/python3.6', '/home/up201505534/miniconda/envs/dammit/lib/python3.6/lib-dynload', '/home/up201505534/miniconda/envs/dammit/lib/python3.6/site-packages']

还有Python：

/opt/python:/opt/lib64/python2.7/site-packages:/opt/lib/python2.7/site-packages:/opt/lib64/python3.7/site-packages:/opt/lib/python3.7/site-packages:
