conda create出现连接问题_创建conda环境：“发现冲突！”当解决环境和“寻找最短冲突路径”运行时...
我得到了一个environment.ubuntu.yml文件，可以创建conda环境。但是，运行conda create env --file environment.ubuntu.yml会得到以下输出：conda env create --file environment.ubuntu.yml

Finding shortest conflict path持续了很长一段时间-显然它试图解决一些依赖性问题。已经运行了两个小时，现在还不清楚它是否会停止。
我的问题是：这里发生了什么，我能以某种方式手动加速这个过程吗，例如通过删除不必要的依赖项？因为我没有创造环境，我不知道哪些是真正必要的。
我之所以好奇，是因为当dependencies中的冲突路径是2.13.1并且我已经通过2.13.1安装它时，它正在检查fontconfig[version='>=2.12.6,<3.0a0']这样的冲突路径
