python - conda 更新导致 ImportError : No module named tqdm

Question

每当我尝试使用 conda 更新任何内容时，都会收到错误:ImportError:没有名为 tqdm 的模块。这是完整的回溯:

$ conda update conda
Traceback (most recent call last):
  File "/Users/user/anaconda2/bin/conda", line 13, in <module>
    sys.exit(main())
  File "/Users/user/anaconda2/lib/python2.7/site-packages/conda/cli/main.py", line 150, in main
    return conda_exception_handler(_main, *args, **kwargs)

  File "/Users/user/anaconda2/lib/python2.7/site-packages/conda_package_handling/api.py", line 5, in <module>
    import tqdm
ImportError: No module named tqdm

但是，当我尝试使用 pip 安装 tqdm 时，它说它已经安装了:

$ pip install tqdm
Requirement already satisfied: tqdm in /usr/local/lib/python2.7/site-packages (4.32.2)

我在 MacOS Mojave 上使用 Python 2.7，没有虚拟环境。如何修复 conda？

编辑: 我也尝试过:python -m pip install tqdm但它说要求已经满足。

然后我尝试了:/Users/user/anaconda2/bin/python -m pip install tqdm，但它也说要求已经满足:要求已经满足:tqdm in ./anaconda2/lib/python2.7/site-packages (4.31.1)

我最终删除并重新安装了 anaconda，这解决了问题。
