问题描述

我一直在努力使biopython正常工作,似乎我在此过程中破坏了conda.此时,将显示conda的帮助菜单,并且conda --version返回conda 4.7.5,但是其他任何内容(包括conda info)都将引发错误AttributeError: dlsym(0x1004381c0, archive_read_open_filename_w): symbol not found

I was playing around with trying to get biopython working and it seems like I broke conda in the process. At this point, the help menu for conda will display, and conda --version returns conda 4.7.5 but anything else including conda info throws an error AttributeError: dlsym(0x1004381c0, archive_read_open_filename_w): symbol not found

这是在Mac OS 10.14.4上. Conda只是在工作,我最后一次使用它来安装biopython而不出现错误conda install -c conda-forge biopython.运行import Bio仍然会导致ImportError: No module named Bio.因此,在故障排除中,我运行了pip uninstall biopython(表示已成功卸载biopython-1.73)和pip install biopython,返回了:

This is on Mac OS 10.14.4. Conda was just working and I last used it to install biopython without error conda install -c conda-forge biopython. Running import Bio still resulted in an a ImportError: No module named Bio. So in troubleshooting I ran pip uninstall biopython (which said it successfully uninstalled biopython-1.73) and pip install biopython which returned:

Requirement already satisfied: biopython in /Users/dmattox/anaconda/lib/python2.7/site-packages (1.73)
Requirement already satisfied: numpy in /Users/dmattox/anaconda/lib/python2.7/site-packages (from biopython) (1.13.1)

然后我再次尝试使用conda conda install -c conda-forge biopython进行安装,该错误返回了我从conda info上面显示的相同错误.每当我尝试使用conda进行任何操作时,都会出现此AttributeError.我在下面包括了回溯.有什么建议吗?

I then tried installing with conda again conda install -c conda-forge biopython which returned the same error I showed above from conda info. This AttributeError appears anytime I try and use conda for anything now. I've included the traceback below. Any suggestions?

以下是我解决该问题的步骤,希望对您有所帮助:

Here are the steps how I solve it, Hope it's helpful to you:

在Mac上导致此错误的原因是之前已安装Python,我试图删除所有python和Anaconda文件,然后再次安装anaconda,然后成功运行conda命令.

The reason caused this error on Mac is Python was installed before, I tried to delete all the python and Anaconda files, and install the anaconda again, then run the conda command successfully.

  1. 从Macintouch-> Frameworks-> PythonFramework-> Versions-> 3.x中删除python
  2. 删除.bash_profile中有关python和anaconda的所有记录(通过shift + command +查找此隐藏文件.)
  3. 在应用程序中删除anaconda导航器
  4. 再次安装Anaconda
