Could not find a version that satisfies the requirement yaml ， no matching distribution found for ya

python 3 pip install yaml时候，总是提示没找到yaml的版本

具体提示如下：

ERROR: Could not find a version that satisfies the requirement yaml (from versio
ns: none)
ERROR: No matching distribution found for yaml

然后百度了下，说是可以用pip3 install 尝试，还是不行

又有说Python3.6不支持，我的是3.8版本Python，还是想用yaml

最后问了其他伙伴，给的建议 pip install pyyaml 尝试成功了
