【中文标题】使用 conda 在 Windows 上构建 Python 包时出现奇怪的“拒绝访问”错误【英文标题】：Strange "Access Denied" error when building a Python package on Windows using conda 【发布时间】：2019-08-17 22:15:06 【问题描述】：我正在尝试构建 Chaco 包，使用：
conda build --numpy=1.16 --use-local conda.recipe\chaco
我在构建过程中遇到了这个非常奇怪的错误：

因此，很明显，构建过程没有拒绝访问。
当这第一次发生时，我想，“哦，哦！Anaconda3 安装损坏了。” 因此，我卸载了 Anaconda3，确保我在所有 Windows (7-Pro) 更新上都是最新的，重新启动并重新安装了 Anaconda3。 我得到完全相同的错误！

根据this post 中的建议，我尝试卸载 Anaconda3 并重新安装“只为我”，这具有在我的主目录下安装 Anaconda3 的效果。
行为没有变化：仍然收到同一文件的“访问被拒绝”错误：fonttools.exe。
问题： 有没有办法可以进入Chaco 构建目录并手动完成构建/上传，这样我就可以在等待的同时发布此 PyBERT 更新的 Windows 版本回复我的帖子？
【问题讨论】：
看起来有点类似于在 Windows 上困扰 R 包安装很长一段时间的错误：由于防病毒软件同时扫描目录，R 无法重命名目录。在 IIUC，Anaconda 正在尝试移动一个 exe 文件：它是否也与防病毒软件有关？您可以尝试在构建期间关闭 AV。 @Jean-ClaudeArbaut，感谢您的建议。我尝试暂时关闭我的杀毒软件，但没有任何乐趣；我得到完全相同的行为。 :( 【参考方案1】：FWIW - 在您在 Anaconda 中找到解决方案之前，另一种可能的解决方法是使用 Enthought 部署管理器 (EDM) 安装环境，该管理器在 Win/Lin/Mac 上为 CPython 2.7.15、3.5 提供 chaco 4.8.0 .2 和 3.6.5 EDM Product Description and Download, EDM Documentation
【讨论】：
其实 3.6.5 已经可以使用了@dbanas以上是关于使用 conda 在 Windows 上构建 Python 包时出现奇怪的“拒绝访问”错误的主要内容，如果未能解决你的问题，请参考以下文章
