makeinstall

python3.7先找的解释器位置一般为:

/usr/local/bin/python3.7

四、删除原软连接

rm-rf/usr/bin/python3
rm-rf/usr/bin/pip3

5.添加python3的软连接

ln-s/usr/local/bin/python3.7/usr/bin/python3
#添加pip3的软链接
ln-s/usr/local/bin/pip3.7/usr/bin/pip3

六、备忘问题

问题一： Modulenotfounderororrororord: No module named '_ctypes'

sudoapt-getupdate
sudoapt-getupgrade
sudoapt-getdist-upgrade
sudoapt-getinstallbuild-essentialpython-devpython-setuptoolspython-pippython-smbus
sudoapt-getinstallbuild-essentialibncursesw5-devlibgdbm-devlibc6-dev
sudoapt-getinstallliblib1g-devlibsqlite3-devtk-dev
sudoapt-getinstalllibssl-devopenssl
sudoapt-getinstalllibffi-dev

问题二： zipimport.ZipImportError: can’t decompress data; zlib not available
