安装condaforge:：protobuf3.8.0时，Conda package install[Errno 13]权限被拒绝

Question

我有一个带有python3.6的conda环境，我的Pytorch安装出现了问题，所以我尝试再次安装它。在安装即将结束时，我遇到以下错误：

ERROR conda.core.link:_execute(700): An error occurred while installing package 'conda-forge::protobuf-3.8.0-py36h6de7cb9_1'.
Rolling back transaction: done

[Errno 13] Permission denied: '/Users/myusername/anaconda3/envs/torch/lib/python3.6/site-packages/google/protobuf/__init__.py'
()

此外，它还说“环境不一致”，这可能是已经出了问题的线索。你知道吗

详细信息：

$ conda install pytorch torchvision -c pytorch

更新： 我尝试卸载tensorboard和tensorboardx，但同样的错误发生，阻止卸载。你知道吗

此外：

尝试pip uninstall protobuf，但导致了类似的错误：

Uninstalling protobuf-3.10.0:

除了删除整个环境并重新开始之外，我不知道如何解决这个问题。你知道吗

Answer 1

多亏了this answer，我找到了一个解决问题的方法：

sudo pip uninstall protobuf

之后是

conda install pytorch torchvision -c pytorch
