安装python库时具体怎样怎样执行python setup.py install
现进入CMD，然后输入DOS命令进入setup.py文件所在目录，然后输入python setup.py install就搞定了。
python3.7安装失败
主要是要知道哪里出现问题了啊，点log file看问题出在哪。比如说看操作系统是否匹配，3.7.3仅支持Windows Vista和更新的操作系统版本，不支持XP，如果需要在Windows XP装的话，只能安装Python 3.4及之前版本。只有知道问题在哪，才好出谋划策。
Django安装输入python setup.py install 无效
setup.py文件没有在当前目录下，cd到解压目录下安装，
另外安装django的方法有好几种,下载easy_install或者pip工具
easy_install django==1.5.1
pip install django==1.5.1
高分求python setup.py install 安装出现问题？提示：ImportError: No module named Shared.DC.ZRD
看情况是你的安装包不完整。少了些内容。
shared.dc.zrdb.tm这个包从命名规则上看是一个习惯在windows下编程的人做的。unix和python都是对大小敏感的。所以为了程序的移植性，通常都不使用大小写来命名。
从内容上看，似乎是一个WEB的爬行器，有一个大的URL库，其中库有可能是从网上下载使用的。
所以你可以尝试从网上重新下载完整的安装包。或者是旧的安装包。旧的安装包里也许有这个文件，先安装旧的。再安装新的也许就没有问题了。
为什么python安装包的setup.py没有对应的uninstall参数

python怎么安装第三方类库
使用pip
大多数库都可以通过pip安装，安装方法为，在命令行窗口输入
pip install libname
libname为库名
某些库通过pip安装不了，可能是因为没有打包上传到pypi中，可以下载安装包之后离线安装，方法是
pip install libpath
libpath为本地安装包地址，这些安装包一般以whl为后缀名。表示python扩展包的windows环境下的二进制文件。
有一个专门下载这种文件的地方，是由加利福尼亚大学的师生为方便python用户使用而建立的，并非官方出品，使用时需自行承担风险。
源文件安装
如果下载下来的安装包为带有源文件的压缩包，解压之后，运行setup.py进行安装，方法是
命令行切换到安装包中setup.py文件所在的目录，执行 python setup.py install
运行安装包
有些类库提供了双击运行直接安装的安装包，比如python连接mysql数据库的驱动 mysql-connector-python
这些安装包的后缀名为msi或者exe。下载下来之后，双击运行之后就安装好了，前提是要根据python的版本及windows的位数下载对应的安装包，否则安装过程会报错或者直接提示无法安装。
