  File "1.py", line 6, in <module>
    tar = tarfile.open("sample.tar.gz", "w:gz")
  File "/usr/local/python3/lib/python3.5/tarfile.py", line 1580, in open
    return func(name, filemode, fileobj, **kwargs)
  File "/usr/local/python3/lib/python3.5/tarfile.py", line 1624, in gzopen
    raise CompressionError("gzip module is not available")
tarfile.CompressionError: gzip module is not available

解决办法

先按照zlib模块，在编译安装

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y

./configure --prefix=/data/app/python-3.5.2 --enable-shared
make
make install

执行命令继续报错
