使用cond在Windows上构建Python包时出现奇怪的“拒绝访问”错误

Question

我试图使用以下方法构建Chaco包：

conda build --numpy=1.16 --use-local conda.recipe\chaco

我在构建过程中遇到了一个非常奇怪的错误：

Using c:\programdata\anaconda3\conda-bld\chaco_1566078508037\_h_env\lib\site-packages

但是，当我检查C:\ProgramData\Anaconda3\conda-bld\chaco_1566078508037\_h_env\Scripts\目录的内容时，我看到fonttools.exe文件：

^{pr2}$

所以，很明显，构建过程是被拒绝访问的。在

当这第一次发生的时候，我想，“啊哦！已损坏的Anaconda3安装。“ 所以，我卸载了Anaconda3，确保所有Windows（7-Pro）更新都是最新的，重新启动并重新安装了Anaconda3。 我也犯了同样的错误！在

我的conda.recipe\chaco\meta.yaml文件的内容，供参考：

还有我的bld.bat：

"%PYTHON%" setup.py install 
if errorlevel 1 exit 1

根据this post中的建议，我尝试卸载Anaconda3并重新安装“just for me”，其效果是在我的主目录下安装Anaconda3。 行为没有变化：仍然收到同一文件的“拒绝访问”错误：fonttools.exe。在

问题：有没有一种方法可以让我进入Chaco构建目录并手动完成构建/上传，这样我就可以在等待帖子回复的同时发布这个PyBERT更新的Windows版本？在

FWIW在Anaconda中找到解决方案之前，另一个可能的解决方案是使用enthough Deployment Manager（EDM）安装一个环境，它在Win/Lin/Mac上为CPython 2.7.15、3.5.2和3.6.5提供chaco4.8.0 EDM Product Description and Download， EDM Documentation
