Ubuntu下运行scrapy爬虫框架No module named 'OpenSSL'

终端运行启动新项目scrapy startproject tutorial

出现报错：
Traceback (most recent call last):
  File "/usr/local/bin/scrapy", line 11, in <module>
    sys.exit(execute())
.

.
  File "/usr/local/lib/python3.5/dist-packages/scrapy/utils/versions.py", line 43, in _get_openssl_version
    import OpenSSL
ImportError: No module named 'OpenSSL'

解决方法：终端输入先删除原OpenSSL包 rm -rf /home/croline/.local/lib/python3.5/site-packages/OpenSSL
再重新安装 ：

sudo pip install pyOpenSSL==0.15.1

sudo pip install --upgrade pyOpenSSL

再次报错：
Traceback (most recent call last):
  File "/usr/local/bin/pip", line 9, in <module>
    load_entry_point('pip==19.0.2', 'console_scripts', 'pip')()
 .

.
  File "/usr/local/lib/python3.5/dist-packages/OpenSSL/SSL.py", line 118, in <module>
    SSL_ST_INIT = _lib.SSL_ST_INIT
AttributeError: module 'lib' has no attribute 'SSL_ST_INIT'

解决方法：sudo easy_install3 --upgrade pyOpenSSL
最后终于全部解决！
