Python安装包：can'；t使用pip install命令安装软件包

我一直试图在anaconda提示符下使用pip install命令在我的conda环境中安装vertex软件包，但我不断收到以下警告和错误：

pip install vertex

大约一周前，我在安装scipy时遇到了同样的问题，但我通过使用以下命令成功绕过了它：

conda install -c conda-forge scipy

它成功了，然后我将康达·弗朗奇频道添加到我的环境中。尝试使用conda install命令安装vertex软件包时，我收到一条消息，它在当前通道中找不到vertex软件包，并且我没有为此找到合适的通道。命令行：

conda install vertex

无论哪种方式，我都无法在我的conda环境中安装vertex软件包

提前感谢所有帮助人员：）

此软件包在Anaconda Cloud上似乎不可用，其历史记录已有几年，没有更新。略过项目，它看起来不处于活动维护状态，因此您可能无法通过包管理器安装它（如果有的话）。

您可以尝试避免混合多个包源。这样做会降低依赖性问题的可能性。据我所知，在您的环境中，您现在有3个来源：

• 康达
• 康达锻造厂
• 皮普

对于干净的conda环境，pip安装包时不会出现错误

conda create -n vertex-env python=3
conda activate vertex-env
pip install vertex
pip list

使用上面的命令序列，我成功地安装了vertex包，尽管我没有验证运行时

$ pip list

考虑到这个包有多旧，几乎没有理由相信它能与任何Python3版本一起工作。事实上，我们发现缺少一些括号，这意味着Python3不兼容。因此，请尝试Python 2.7版本，让Pip解决除Python和Pip之外的所有问题：

vertex.yaml

名称：顶点
频道：
-康达锻造厂
-默认值
-免费的
依赖项：
-python=2.7
-皮普
-pip：
-顶点
-服务标识

然后从shell（例如bash）开始：

conda env create-n vertex-f vertex.yaml
康达激活顶点

这使得Vertex在加载我在测试中发现的一些模块（例如，Vertex import q2q中的

）时能够安装并且不会抛出错误，但我没有运行实际的测试。
是的，你是对的，但是我知道我班上的人能够毫无问题地安装该软件包（我在课程项目中需要它）。考虑到一周前我在使用pip命令安装scipy时遇到问题，我不认为这是安装失败的原因。不管怎样，谢谢。我试过你写的东西，但还是不起作用。我还尝试完全卸载anaconda并重新安装它，然后执行您编写的操作，但仍然不起作用。还是谢谢你的努力。@Niv听起来不错。确保文件中的间距与我提供的间距完全匹配（YAML对空白敏感）。因为你在Windows上，你可能需要启动一个Anaconda提示符会话，而不是默认的命令提示符。它仍然抛出与帖子中相同的错误。对于我的班级项目要求，我需要python 3.7.x
