查看系統python版本python
python Python 2.7.9 (default, Mar 1 2015, 18:22:53) [GCC 4.9.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>>
1.更新軟件包linux
apt-get update apt-get upgrade
2.安裝依賴包flask
aptitude -y install gcc make zlib1g-dev libffi-dev libssl-dev
若是提示-bash: aptitude: command not found
,則表示你的機子須要安裝aptitude
,安裝命令以下:bash
apt-get install aptitude
3.下載 Python 3.6.5ui
wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
4.解壓壓縮包code
tar -xvf Python-3.6.5.tgz
5.受權文件夾權限orm
chmod -R +x Python-3.6.5
6.進入文件夾,並執行安裝配置ip
cd Python-3.6.5/ ./configure
或者將python3安裝到其它目錄下ssl
./configure --prefix=/opt/python3.6.5
會提示如下信息get
If you want a release build with all optimizations active (LTO, PGO, etc), please run ./configure --enable-optimizations.
按照提示進行執行代碼,參考連接:http://stackoverflow.com/ques...
注意,若是按照提示執行了代碼,那麼剛纔設置的指定安裝路徑則無效,會安裝到 usr/local/bin 裏面。若是你只想用 python3 來執行 flask,那麼是否安裝到指定目錄,對你的目標並無影響。 ./configure --enable-optimizations
7.安裝依賴包,
aptitude -y install libffi-dev libssl-dev
8.編譯安裝
make && make install
顯示下面代碼則表示安裝成功
Collecting setuptools Collecting pip Installing collected packages: setuptools, pip Successfully installed pip-9.0.1 setuptools-28.8.0
9.清理配置文件(有沒有必要進行這一步,我也不知道。)
make clean make distclean
10.添加快捷方式
# ln -s /opt/python3.6.5/bin/python3.6 /usr/bin/python3 # ln -s /opt/python3.6.5/bin/pip3.6 /usr/bin/pip3.6 # ln -s /opt/python3.6.5/bin/pip3 /usr/bin/pip3 # ln -s /opt/python3.6.5/bin/pyvenv-3.6 /usr/bin/pyvenv
