python下setuptools的安装详解及No module named setuptools的解决方法
前言
python下的setuptools带有一个easy_install的工具,在安装python的每三方模块、工具时很有用,也很方便。
安装setuptools前先安装pip,请参考:linux下pip的安装步骤及使用详解
1. 下载:
在它的官网可以下载到安装包:
https://pypi.python.org/pypi/setuptools
页面最下面的是它的安装链接,如:
$wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-12.0.3.tar.gz#md5=f07e4b0f4c1c9368fcd980d888b29a65
2. 安装
$ tar -zxvf setuptools-12.0.3.tar.gz $ cd setuptools=12.0.3 $ python setup.py install
3. 出现错误提示:
Installed /usr/local/python2.7.3/lib/python2.7/site-packages/supervisor-4.0.0_dev-py2.7.egg Processing dependencies for supervisor==4.0.0-dev Searching for meld3>=1.0.0 Reading https://pypi.python.org/simple/meld3/ Download error on https://pypi.python.org/simple/meld3/: [Errno 1] _ssl.c:504: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed -- Some packages may not be found! Couldn't find index page for 'meld3' (maybe misspelled?) Scanning index of all packages (this may take a while) Reading https://pypi.python.org/simple/ Download error on https://pypi.python.org/simple/: [Errno 1] _ssl.c:504: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed -- Some packages may not be found! No local packages or download links found for meld3>=1.0.0 error: Could not find suitable distribution for Requirement.parse('meld3>=1.0.0')
解决办法:
上网查询了问题原因: 是curl的证书太老了需要下载最新的证书:
下载最新的证书文件
$ wget http://curl.haxx.se/ca/cacert.pem
更名为ca-bundle.crt放置到默认目录
$ mv cacert.pem ca-bundle.crt $ mv ca-bundle.crt /etc/pki/tls/certs
