centos PermissionError: [Errno 13] Permission denied: 'geckodriver'

运行一个爬虫文件时运到错误 centos PermissionError: [Errno 13] Permission denied: 'geckodriver'

Traceback (most recent call last):
  File "/home/crawl/lib/python3.6/site-packages/selenium/webdriver/common/service.py", line 76, in start
    stdin=PIPE)

During handling of the above exception, another exception occurred:

网上没有相应的博客，因此我大展身手的机会又来了

原因：爬虫文件无法调用 'geckodriver'

解决方案：更改 'geckodriver'权限

更改执行权限

完美解决
