如何从没有环境名称的文本文件创建新环境？

Question

我正在尝试使用Udacity here提供的给定文件在Anaconda中创建一个新环境。但是，我一直收到这个错误：

  

SpecNotFound：无法处理名称

我认为这是因为在给定的文件中，环境没有名称。我注意到这一点是因为在我当前环境的导出的yaml文件中，我的格式与上面给出的requirements.txt文件格式不同。

所以问题是，如何使用the given file创建新环境？谢谢！

Answer 1

我遇到了同样的错误。我的文件也具有txt扩展名。 我将其更改为yml，并且按预期工作！

（在Ubuntu 18.10上测试）

Answer 2

这似乎是一个pip需求文件而不是conda environment.yaml文件。

您可以使用

在您的环境中通过pip安装所有这些（首先激活它）

pip install -r requirements.txt

或者，如果您需要（我怀疑），要使用conda包管理器进行安装，您可以使用此处引用的任一方法 - Install only available packages using "conda install --yes --file requirements.txt" without error

conda install --yes --file requirements.txt

但请注意，如果在默认频道中找不到要求，则可能会失败。

您可以通过链接问题中的命令编写脚本安装脚本;

while read requirement; do conda install --yes $requirement; done < requirements.txt

或者确实如此，尽可能使用conda，但如果没有，则回退到pip;

$ while read requirement; do conda install --yes $requirement || pip install $requirement; done < requirements.txt

Answer 3

将文件扩展名更改为.yml，然后在anaconda命令提示符下运行以下命令。

C:\Directory\conda env create -f file.yml

这将自动安装所有库。
