問(wèn)題描述

阿里云主機(jī)，原本centos內(nèi)置python 2.7 ，安裝了python 3.6然后因?yàn)橐褂胠xml 解析文檔，結(jié)果使用

pip3 install lxml

Collecting lxml HTTP error 404 while getting http://mirrors.aliyun.com/pypi/packages/0a/75/d54af657adc8625aa950ae7be4e4f33ef2b5014380556790fc6c7b7d095d/lxml-3.8.0-cp36-cp36m-manylinux1_x86_64.whl#md5=0cf2148ff4e6e65bf9f0bb0c97733f2f (from http://mirrors.aliyun.com/pypi/simple/lxml/) Could not install requirement lxml from http://mirrors.aliyun.com/pypi/packages/0a/75/d54af657adc8625aa950ae7be4e4f33ef2b5014380556790fc6c7b7d095d/lxml-3.8.0-cp36-cp36m-manylinux1_x86_64.whl#md5=0cf2148ff4e6e65bf9f0bb0c97733f2f because of error 404 Client Error: Not Found for url: http://mirrors.aliyun.com/pypi/packages/0a/75/d54af657adc8625aa950ae7be4e4f33ef2b5014380556790fc6c7b7d095d/lxml-3.8.0-cp36-cp36m-manylinux1_x86_64.whlCould not install requirement lxml from http://mirrors.aliyun.com/pypi/packages/0a/75/d54af657adc8625aa950ae7be4e4f33ef2b5014380556790fc6c7b7d095d/lxml-3.8.0-cp36-cp36m-manylinux1_x86_64.whl#md5=0cf2148ff4e6e65bf9f0bb0c97733f2f because of HTTP error 404 Client Error: Not Found for url: http://mirrors.aliyun.com/pypi/packages/0a/75/d54af657adc8625aa950ae7be4e4f33ef2b5014380556790fc6c7b7d095d/lxml-3.8.0-cp36-cp36m-manylinux1_x86_64.whl for URL http://mirrors.aliyun.com/pypi/packages/0a/75/d54af657adc8625aa950ae7be4e4f33ef2b5014380556790fc6c7b7d095d/lxml-3.8.0-cp36-cp36m-manylinux1_x86_64.whl#md5=0cf2148ff4e6e65bf9f0bb0c97733f2f (from http://mirrors.aliyun.com/pypi/simple/lxml/)

請(qǐng)教各位如何解決？按照網(wǎng)上說(shuō)的額

pip3 install wheel

然而還是沒(méi)用請(qǐng)教倒是是怎么解決

當(dāng)然如果直接用pip 那么是python 2.7的根據(jù)這個(gè)帖子 centos python安裝lxml報(bào)錯(cuò)

yum groupinstall development toolsyum install python-devel

發(fā)現(xiàn)安裝的都是python 2.7的結(jié)果還是報(bào)錯(cuò)

問(wèn)題解答

看到報(bào)錯(cuò):

because of error 404 Client Error: Not Found for url: http://mirrors.aliyun.com/pypi/packages/0a/75/d54af657adc8625aa950ae7be4e4f33ef2b5014380556790fc6c7b7d095d/lxml-3.8.0-cp36-cp36m-manylinux1_x86_64.whl

可能是yum源配置有問(wèn)題, 可以先嘗試換一個(gè)yum源, 然后再試下安裝參考下這個(gè): CentOS 7 安裝EPEL源然后再參考下面的, 安裝lxmlcentos7安裝python,pip,redis,lxml

使用pip3 install lxml -v 打印更多信息,我估計(jì)系統(tǒng)沒(méi)裝libXXXdev所致
