Centos上安装python3.5以上版本,centospython3.5,h3 { color
一、准备工作:
yum installzlib-devel
yum installopenssl-devel
二、安装python3.5
wgethttps://www.python.org/ftp/python/3.5.3/Python-3.5.3.tgz
tar -zxvfPython-3.5.3.tgz
cdPython-3.5.3
./configure --prefix=/usr/local/python3 --enable-shared
make && make install
三、替换系统中的python
mv /usr/bin/python python.bak
ln -s /usr/local/python3.5/bin/python3 /usr/bin/python
由于更改系统默认的python会影响yum,需修改如下两个文件:
/usr/bin/yum和/usr/libexec/urlgrabber-ext-down
1 Known problems with Fedora Linux and Python 3 version: Error message: 2 # yum search package 3 File "/usr/bin/yum", line 30 4 except KeyboardInterrupt, e: 5 ^ 6 SyntaxError: invalid syntax 7 If you set python3 globally on your system change the yumshebang to python2: 8 # vi /usr/bin/yum 9 FROM:10 #!/usr/bin/python11 TO:12 #!/usr/bin/python2.713 Similarly: Error message:14 Downloading packages:15 File "/usr/libexec/urlgrabber-ext-down", line 2816 except OSError, e:17 ^18 SyntaxError: invalid syntax19 Exiting on user cancel20 The issue is also related to Python 3 set as a default global version. To fix this error update/usr/libexec/urlgrabber-ext-down script:21 # vi /usr/libexec/urlgrabber-ext-down22 FROM:23 #!/usr/bin/python24 TO:25 #!/usr/bin/python2.7
四、安装setuptools
wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26
tar -zxvfsetuptools-19.6.tar.gz
cdsetuptools-19.6
python3 setup.py build
python3 setup.py install
(如有报错:RuntimeError: Compression requires the (missing) zlib module,则需要安装yum installzlib-devel,安装后要重新编译 python3.5:
make && make install)
五、安装pip
wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb
tar -zxvfpip-8.0.2.tar.gz
cdpip-8.0.2
python3 setup.py build
python3 setup.py install
使用pip安装包测试:
如报错,则缺少yum installopenssl-devel,安装完成后一样需要重新编译python3.5(make&&make install)
[[email protected] pip-9.0.1]# python -m pip install paramikopip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.Collecting paramiko Could not fetch URL https://pypi.python.org/simple/paramiko/: There was a problem confirming the ssl certificate: Can‘t connect to HTTPS URL because the SSL module is not available. - skipping Could not find a version that satisfies the requirement paramiko (from versions: )No matching distribution found for paramiko
