python3.x - centos python 安裝lxml 錯誤 阿里雲ECS

Question

阿里雲主機，原本centos內建python 2.7 ，安裝了python 3.6
然後因為要使用lxml 解析文檔，結果使用

pip3 install lxml 

Collecting lxml

請教各位如何解決？
依照網路上說的額

pip3 install wheel  

然而還是沒用請教倒是怎麼解決

當然如果直接用pip 那麼是python 2.7的
根據這個帖子 centos python安裝lxml報錯

yum groupinstall development tools
yum install python-devel

發現安裝的都是python 2.7的
結果還是報錯

Answer 1

看到報錯:

because of error 404 Client Error: Not Found for url: http://
mirrors.aliyun.com/pypi/packages/0a/75/d54af657adc8625aa950ae7be4e4f33ef2b5014380556790fc6c7b7d09
5d/lxml-3.8.0-cp36-cp36m-manylinux1_x86_64.whl

可能是yum源配置有問題, 可以先嘗試換一個yum源, 然後再試下安裝
參考下這個: CentOS 7 安裝EPEL源
然後再參考下面的, 安裝lxml
centos7安裝python, pip,redis,lxml

Answer 2

使用pip3 install lxml -v 列印更多資訊,我估計系統沒裝libXXXdev所致
