我通过NoMachine远程进入运行CentOS 7的Linux虚拟机。NoMachine将客户端的麦克风显示为脉冲音频源。我可以使用Audacity从pulseaudio源进行录制。然而,其他应用程序-- Chrome、火狐、松弛、WebEx --看不到或不能识别脉冲音频源是麦克风。test.webrtc.org说是[ FAILED ] Failed to get access to local media due to error: NotFoundError。

我在Ubuntu18.04下使用virtualenv venv -p python3和source venv/bin/activate创建了一个虚拟环境。然后我尝试安装,它会根据需要安装。ConfigSpace安装失败,并抛出以下错误:
Building wheel for ConfigSpace (setup.py) ... error

我遇到了以下问题:我在xUbuntu OS上,正在尝试在Flask应用程序中使用networkx,并且我有以下代码:
.....
import networkx as nx
......
# Creating and initializing graph object which is networkx object
hosts_graph = get_networkx_graph_object()
# Variable 'coord' where the coordinates for each node will be stored
coord = nx.pygraphv
假设我有这种代码:
// In revision.c
char *path_name(const struct name_path *path, const char *name) // by design, name_path->len is a 32 bits int, but this doesn’t concern name
{
const struct name_path *p;
char *n, *m;
int nlen = strlen(name); // the size is converted to a positive numbe
