Linux下原码安装 python-3.

Linux下原码安装 python-3.6.6

• 下载

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

• 安装依赖包

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

• 解压并进入到解压目录

# 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
将以上几行的#号去掉

# 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

• 编译安装

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

• 查看是否安装成功

  # python3

  python3: error while loading shared libraries: libpython3.6m.so.1.0: cannot open shared object file: No such file or directory
  出现以上报错

• 解决以上问题

# 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

• 再次检查安装是否成功

# python3
>>> exit()
# pip3 –V
