Python2.6.6 is installed by default in CentOS 6.5. Since python2.6.6 is used in yum, Install the latest python 2 and python 3 including pip, without breaking this environment. At this time, except pyenv.
-
When installing pip, curl: (35) SSL connect error error occurs, so upgrade libcurl to the latest version as follows. And, in order to fix zipimport.ZipImportError: can not decompress data; zlib not available which occurs when installing pip as well, execute yum upgrade after installing the package.
yum install libcurl sudo rpm -Uvh http://www.city-fan.org/ftp/contrib/yum-repo/city-fan.org-release-1-13.rhel6.noarch.rpm sudo vim /etc/yum.repos.d/city-fan.org.repo sudo yum update --enablerepo=city-fan.org libcurl yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel yum upgrade -
Install python. Here we install Python 2.7.14 and Python 3.6.3. Python 3.7.0a1 is not recommended as it will cause installation errors.
mkdir /usr/local/src cd /usr/local/src curl -O https://www.python.org/ftp/python/2.7.14/Python-2.7.14.tgz tar zxf Python-2.7.14.tgz cd Python-2.7.14 ./configure make && make altinstall -
Replace the default Python with the latest version without deleting Python2.6.6. At this time, do not influence yum.
rm -rf /usr/bin/python2 /usr/bin/python2.6 mv /usr/bin/python /usr/bin/python26 vi /usr/bin/yum ##python -> python26 mv /usr/local/src/Python-2.7.14/python /usr/bin/python python --version # Python 2.7.14 python26 --version # Python 2.6.6 -
Install pip.
curl -kL https://bootstrap.pypa.io/get-pip.py | python pip -V # pip 9.0.1 from /usr/local/lib/python2.7/site-packages (python 2.7)
Although it is unknown whether there is a relation, If you install Python using the above method, errors like libpython/Python2.7.a may occur.
Currently, when trying to install "uwsgi", this error has occurred in both pip install and make.
I plan to write countermeasures at a later date.
