2019獨角獸企業(yè)重金招聘Python工程師標準>>>

一、環(huán)境：

Ubuntu 16.04.5 LTS (GNU/Linux 4.4.0-131-generic x86_64)

二、軟件下載：

https://www.python.org/downloads/

https://www.python.org/ftp/python/3.7.1/Python-3.7.1.tgz

https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz

三、升級系統(tǒng)：

sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade

四、安裝所需的組件：

sudo apt-get install build-essential bzip2 gcc libbz2-1.0 libbz2-dev libc6-dev libdb-dev libexpat1 sudo apt-get install libexpat1-dev libffi-dev libgdbm-dev libgdbm3 liblzma-dev libncurses5-dev libncursesw5-dev sudo apt-get install libpcap-dev libreadline-dev libreadline5 libreadline6 libreadline6-dev sudo apt-get install libsqlite0 libsqlite0-dev libsqlite3-0 libsqlite3-dev libssl-dev libssl1.0.0 sudo apt-get install libxml2-dev libxslt1-dev make openssl python-dev python-pip python-setuptools sudo apt-get install python-smbus python3-dev sqlite sqlite3 tcl tk tk-dev uuid-dev xz-utils zlib1g zlib1g-dev

五、編譯python3.7.1

tar zxvf Python-3.7.1.tgz cd Python-3.7.1 ./configure --prefix=/usr/local/python371 --enable-optimizationsexport CPPFLAGS=" -Wno-error=coverage-mismatch" make -j9sudo ln -s /usr/local/python371/bin/python3 /usr/bin/python371 sudo ln -s /usr/local/python371/bin/python3 /usr/bin/python3.7.1 sudo ln -s /usr/local/python371/bin/pip3 /usr/bin/pip371 sudo ln -s /usr/local/python371/bin/pip3 /usr/bin/pip3.7.1

六、編譯python3.7.0

tar zxvf Python-3.7.0.tgz cd Python-3.7.0sed -i "6s/endif/else/" ./Modules/_uuidmodule.c sed -i "7d" ./Modules/_uuidmodule.c sed -i "s/Werror=implicit-function-declaration/Wno-error/g" ./configure./configure --prefix=/usr/local/python370 --enable-optimizations? make -j9sudo ln -s /usr/local/python370/bin/python3 /usr/bin/python370? sudo ln -s /usr/local/python370/bin/python3 /usr/bin/python3.7.0? sudo ln -s /usr/local/python370/bin/pip3 /usr/bin/pip370? sudo ln -s /usr/local/python370/bin/pip3 /usr/bin/pip3.7.0

七、其他命令

adduser?zhangsan usermod -a -G sudo,root zhangsansudo lsb_release -a

八、python3.7.1出現(xiàn)的錯誤

1.-Werror=implicit-function-declaration

The necessary bits to build these optional modules were not found: _hashlib _ssl To find the necessary bits, look in setup.py in detect_modules() for the module's name.The following modules found by detect_modules() in setup.py, have been built by the Makefile instead, as configured by the Setup files: _abc atexit pwd time

解決方式：修改configure文件（sed -i "s/Werror=implicit-function-declaration/Wno-error/g" configure）

2.錯誤：unknown type name ‘uuid_t’ 和錯誤-Werror=coverage-mismatch

?解決方法：設(shè)定環(huán)境變量（export CPPFLAGS=" -Wno-error=coverage-mismatch"）修改文件
