軟連接
自3.4版本起，setup_tools及pip工具自動(dòng)安裝，所以不用再手動(dòng)安裝了

錯(cuò)誤及解決
錯(cuò)誤1
[zhangxinming@localhost Python-3.6.1]$ sudo python3
python3: error while loading shared libraries: libpython3.6m.so.1.0: cannot open shared object file: No such file or directory
[zhangxinming@localhost Python-3.6.1]$ sudo pip3 install numpy

這兩類是一個(gè)錯(cuò)誤，因?yàn)閹觳辉趐yhon3這個(gè)程序可以正確連接的地方。有兩種解決方案麸折，一種是在./configure加入LDFLAGS="-Wl,-rpath /usr/local/lib" 手動(dòng)指定，另一種是設(shè)定全局變量LD_LIBRARY_PATH粘昨。顯然第一種方案更好一些垢啼，第二種方案導(dǎo)致普通用戶程序感染root程序的執(zhí)行，危害很大张肾。
