[英]Error installing conda packages: conda.core.link:_execute(696): An error occurred while installing package 'conda-forge::qt-5.9.7-h506e8af_3'
I'm trying to update packages, and I'm as it goes through the process it eventually stops and rolls back without updating.我正在尝试更新软件包,并且在整个过程中它最终会停止并回滚而不更新。 I'm trying to run this (I've also tried with other packages like astroML, basemap, nltk, etc with similar effect):我正在尝试运行它(我也尝试过使用其他包,如 astroML、basemap、nltk 等,具有类似的效果):
conda install conda --update-all
And this is the error I'm getting:这是我得到的错误:

I've already tried out answers for conda.core.link:_execute(637) and the chcp error with no luck.我已经尝试过conda.core.link:_execute(637)和chcp 错误的答案, 但没有运气。 If I try to update through the Anaconda Navigator it looks like I'm getting the same results.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。 I appreciate any help in understanding and resolving this issue, thanks!感谢您在理解和解决此问题方面的任何帮助,谢谢!
It might not be the most practical solution, but since you already tried the answers from the previous questions, you might just want to re-install conda.这可能不是最实用的解决方案,但由于您已经尝试了之前问题的答案,您可能只想重新安装 conda。 It takes a while, but for me that was the only fix that worked.这需要一段时间,但对我来说,这是唯一有效的修复方法。
Unfortunately that means that you'll remove all your environments as well, so this might be the perfect time to create an environment.yml file for them (or pat yourself on the back if you already have them).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,请拍拍自己的背)。
i once faced same trouble after 3 hours googling i found the solution every error which end with statement .qt-post-link.bat it caused by the windows administrator access, so open your CMD as an administrator and then execute the command.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,每个错误都以语句 .qt-post-link.bat 结尾,它是由 Windows 管理员访问引起的,因此以管理员身份打开您的 CMD,然后执行命令。
here my result这是我的结果
