python - AttributeError：dlsym（RTLD_DEFAULT，AbsoluteToNanoseconds）：找不到符号

问题描述

我正在尝试在 macOS Mojave 上运行“conda install something”，但我每次都会遇到此错误：

conda install update

这是整个回溯：

Traceback (most recent call last):
  File "/anaconda2/bin/conda", line 13, in <module>
    sys.exit(main())
  File "/anaconda2/lib/python2.7/site-packages/conda/cli/main.py", line 149, in main

    func = self.__getitem__(name)
  File "/anaconda2/lib/python2.7/ctypes/__init__.py", line 384, in __getitem__
    func = self._FuncPtr((name_or_ordinal, self))
AttributeError: dlsym(RTLD_DEFAULT, AbsoluteToNanoseconds): symbol not found

我该如何解决？

解决方案

我在 macOS Big Sur 上发生了类似的错误，删除 miniconda2 并安装 miniconda3 对我有用。

我按照https://docs.conda.io/en/latest/miniconda.html上的说明进行操作，基本上是：

rm -rf ~/miniconda2
rm -rf ~/.condarc ~/.conda ~/.continuum
bash Miniconda3-latest-MacOSX-x86_64.sh # after downloading the installable
