Question

这里是python版本:

Python 3.6.5 

我想安装 ruamel:

pip3 install ruamel

但我无法安装它:

(venvpython3) d3alg@ubuntu-59:/$ python
Python 3.6.5 (default, Apr  1 2018, 05:46:30)
[GCC 7.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()

Collecting ruamel
  Could not find a version that satisfies the requirement ruamel (from versions: )
No matching distribution found for ruamel

我做错了什么？

Answer 1

如果您搜索 PyPI对于 ruamel ，您会看到没有具有该名称的包。所有可用的包都将该字符串作为命名空间 (ruamel.)。实际上，您必须选择要安装的每个包(尽管有些包会依赖于其他包并引入多个“ruamel.”命名空间包):

pip3 install -y ruamel.yaml
