Linux下原碼安裝 python-3.6.6

• 下載

                  
                    # wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz
                  
                

• 安裝依賴包

                  
                    # yum -y install zlib-devel bzip2-devel openssl-devel sqlite-devel readline-devel gcc
                  
                

• 解壓并進入到解壓目錄

            
              # tar xvf Python-3.6.6.tgz
# cd Python-3.6.6/

            
          

• 修改 Modules/Setup.dist

167 #readline readline.c -lreadline –ltermcap
210 #SSL=/usr/local/ssl
212 #_ssl _ssl.c \
214 # -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
216 # -L$(SSL)/lib -lssl –lcrypto
將以上幾行的#號去掉

            
              # sed -ri 's/^#readline/readline/' Modules/Setup.dist
# sed -ri 's/^#(SSL=)/\1/' Modules/Setup.dist
# sed -ri 's@^#(_ssl)@\1@' Modules/Setup.dist
# sed -ri 's@^#([ \t]*-DUSE)@\1@' Modules/Setup.dist
# sed -ri 's@^#([ \t]*-L\$\(SSL\))@\1@' Modules/Setup.dist
            
          

• 編譯安裝

                  
                    # ./configure --enable-shared
  # make && make install
                  
                

• 查看是否安裝成功

                  
                    # python3
                  
                

  python3: error while loading shared libraries: libpython3.6m.so.1.0: cannot open shared object file: No such file or directory
  出現以上報錯

• 解決以上問題

            
              # find /usr/local/lib/ -name "libpython3.6m.so.1.0"
/usr/local/lib/libpython3.6m.so.1.0
# vim /etc/profile.d/python3_lib.sh
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
# source /etc/profile

            
          

• 再次檢查安裝是否成功

            
              # python3
>>> exit()
# pip3 –V
