【问题标题】:Error installing conda packages: conda.core.link:_execute(696): An error occurred while installing package 'conda-forge::qt-5.9.7-h506e8af_3'安装 conda 包时出错:conda.core.link:_execute(696):安装包 'conda-forge::qt-5.9.7-h506e8af_3' 时出错

【问题描述】:

我正在尝试更新软件包,并且我正在经历它最终停止并回滚而不更新的过程。我正在尝试运行它(我也尝试过其他包,如 astroML、底图、nltk 等,效果类似):

conda install conda --update-all

这是我得到的错误:

ERROR conda.core.link:_execute(696): An error occurred while installing package

我已经尝试了conda.core.link:_execute(637)chcp error 的答案,但没有成功。如果我尝试通过 Anaconda Navigator 进行更新,看起来我得到了相同的结果。感谢您对理解和解决此问题的任何帮助,谢谢!

    【解决方案1】:

    这可能不是最实用的解决方案,但由于您已经尝试了前面问题的答案,您可能只想重新安装 conda。这需要一段时间,但对我来说,这是唯一有效的解决方法。

    不幸的是,这意味着您也将删除所有环境,因此这可能是为它们创建 environment.yml 文件的最佳时机(或者如果您已经拥有它们,请拍拍自己的后背)。

      【解决方案2】:

      我曾经在谷歌搜索 3 小时后遇到同样的问题,我找到了解决方案 每个以.qt-post-link.bat语句结尾的错误都是由windows管理员访问引起的,所以以管理员身份打开你的CMD然后执行命令。

      这是我的结果
