我正在尝试让biopython工作,似乎我在这个过程中破坏了conda。此时,将显示 conda 的帮助菜单,并且conda --version
回报conda 4.7.5
但其他任何事情包括conda info
抛出错误AttributeError: dlsym(0x1004381c0, archive_read_open_filename_w): symbol not found
这是在 Mac OS 10.14.4 上。 Conda 刚刚工作,我上次用它来安装 biopython 没有错误conda install -c conda-forge biopython
。跑步import Bio
仍然导致了一个ImportError: No module named Bio
。所以在故障排除时我跑了pip uninstall biopython
(表示它成功卸载了biopython-1.73)并且pip install biopython
返回:
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 安装conda install -c conda-forge biopython
它返回了我上面显示的相同错误conda info
。每当我尝试使用 conda 进行任何操作时,都会出现此 AttributeError 。我在下面包含了回溯。有什么建议么?
