关于python的一次报错处理ansible 1.9.4 has requirement pycrypto>=2.6, but you'll have pycrypto 2.4.1 which is incompatible.
出现报错:
ansible 1.9.4 has requirement pycrypto>=2.6, but you'll have pycrypto 2.4.1 which is incompatible.
这个好弄(坑),直接去官网下载源码包安装就可以了(无语,还是太年轻),你猜到了结果还是不行继续报错,报错还是一模一样。。。。。。。。。。。。。。。
使用pip list 查看确实已经跟新版本了,但是为啥还报错呢?
使用pip uninstall 卸载这个pycrypto包提示
Cannot uninstall 'pycrypto'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.,妈蛋的着了半天没找到方法。
结果看pip文档发现下面的这段话。。。。。。。。。。。。
ip is able to uninstall most installed packages. Known exceptions are:
- Pure distutils packages installed with ``python setup.py install``, which
leave behind no metadata to determine what files were installed.
- Script wrappers installed by ``python setup.py develop``.
明白了吧,pip不能够卸载使用源码包安装的扩展。。。。。。。。。。。。
找到源码包安装后的路径,直接删除掉
rm -rf /usr/lib64/python2.7/site-packages/pycrypto-2.6.1-py2.7.egg-info
在用pip list 查看版本已经降下来了成为2.4的了。。。。吼吼
pip uninstall pycrypto 卸载掉,在用pip install pycrypto 重新安装,默认就是2.6版本了(python2.7目前是这样的2018/5/8)
这个问题解决了:
总结:pip 不可以卸载使用源码安装的扩展,最好使用pip install 安装需要的扩展!!!!!!!!!!!
