Centos上安裝python3.5以上版本

標籤：file   tar.gz   預設   this   erro   can   ora   his   tls   

一、準備工作：

　　yum install zlib-devel

　　yum install openssl-devel

二、安裝python3.5

　　wget https://www.python.org/ftp/python/3.5.3/Python-3.5.3.tgz

　　tar -zxvf Python-3.5.3.tgz

　　cd Python-3.5.3

　　./configure --prefix=/usr/local/python3 --enable-shared

　　make && make install

三、替換系統中的python

　　mv /usr/bin/python  python.bak

　　ln -s /usr/local/python3.5/bin/python3 /usr/bin/python

　　由於更改系統預設的python會影響yum，需修改如下兩個檔案：

　　/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、安裝setuptools

　　wget --no-check-certificate  https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26

　　tar -zxvf setuptools-19.6.tar.gz

　　cd setuptools-19.6

　　python3 setup.py build

　　python3 setup.py install

　　(如有報錯： RuntimeError: Compression requires the (missing) zlib module，則需要安裝yum install zlib-devel，安裝後要重新編譯 python3.5:  

make && make install)

五、安裝pip

　　wget --no-check-certificate  https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb

　　tar -zxvf pip-8.0.2.tar.gz

　　cd pip-8.0.2

　　python3 setup.py build

　　python3 setup.py install

　　使用pip安裝包測試：

　　　　如報錯，則缺少yum install openssl-devel,安裝完成後一樣需要重新編譯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
