我刚刚在 Windows 10 上安装了 conda，但是当我运行“conda info”之类的命令时，我收到以下错误消息：

Traceback (most recent call last):
  File "C:\Users\username\AppData\Local\Continuum\miniconda3\lib\site-packages\conda\exceptions.py", line 1043, in __call__
    return func(*args, **kwargs)

我已尝试按照https://anaconda.org/anaconda/conda-package-handling 和https://github.com/conda/conda/issues/8607 的说明安装“conda_package_handling”，但它不允许我安装它 - 我收到相同的错误消息。我会很感激这方面的任何线索！

【解决方案1】：

我在 ubuntu 16 中遇到了同样的错误，我解决了这个问题如下： 1.https://anaconda.org/conda-forge/conda-package-handling/files，根据你的系统下载合适的版本。我下载了 conda-package-handling-1.3.11-py36_0.tar.bz2。 2. 解压这个文件，然后将'conda-package-handling-1.3.11-py36_0/lib/python3.6/site-packages/conda_package_handling'复制到'/home/emg/anaconda3/lib/python3.6/site-包裹' 3. 也许这个错误可以修复，但是当我运行 'conda info' 时，我遇到了一个新错误，即“ModuleNotFoundError: No module named 'libarchive'” 4.https://pypi.org/project/libarchive/，运行“sudo apt-get install libarchive-dev” 5.终于解决了
