如何查看Django是否安装成功？

方法一：执行命令：Python -c "import djangoprint(django_version())",如果正确会返回Django的版本号，如图： 方法二： 首先执行：Python，进入Python命令模式。接着执行命令：import Django。再执行命令：Django.get_version()。返回你的Django版本号，则说明已正确安装。 如图参考：

你需要自己安装一个源外的python类库, 而这个类库内含需要编译的调用python api的c/c++文件

你自己写的一个程序编译需要链接libpythonXX.(a|so)

(注:以上不含使用ctypes/ffi或者裸dlsym方式直接调用libpython.so)

其他正常使用python或者通过安装源内的python类库的不需
