今天在云服务器上安装了svn。使用客户端check out的时候,出错了,提示如下:OPTIONS of 'http://xxxxx/svn': Could not read status line:connection was closed by server (http://xxxxx)。请问怎么解决,网上找了半天,也处理不好。selinux没启动。
$ pip install httplib
Collecting httplib
Could not find a version that satisfies the requirement httplib (from versions: )
No matching distribution found for httplib
怎么让它起作用?
我将Python3.6.9升级到Python3.9。在升级之前,我能够使用opencv,但不知怎么我不能使用opencv和其他库(matplotlib.pyplot等)。这有什么问题吗?
我也尝试过升级opencv,但它给了我这行0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded
任何帮助都是非常感谢的。
