Python setup.py开发与安装（python setup安装教程）

在setup.py两个选项develop，并install混淆了我。根据此站点，使用develop创建到site-packages目录的特殊链接。

人们建议我使用python setup.py install全新安装，并且python setup.py develop对安装文件进行任何更改之后。

任何人都可以阐明这些命令的用法吗？

小编典典

python setup.py install 用于安装（通常是第三方）你不会自行开发/修改/调试的软件包。

对于你自己的东西，你想先安装你的软件包，然后能够频繁编辑代码而不必每次都重新安装软件包-正是python setup.py develop这样：它会安装软件包（通常只是一个源文件夹）以某种方式，你可以在将代码安装到（虚拟）环境后方便地编辑代码，并使更改立即生效。

请注意，强烈建议使用pip install .（安装）和pip install -e .（开发人员安装）来安装软件包，因为setup.py直接调用将对许多依赖项（例如pull prereleases和不兼容的软件包版本）做错事，或者使软件包难以使用卸载pip。

ERROR: Command "python setup.py egg_info" python-nss

[root@localhost ~]# pip install python-nss

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won''t be maintained after that date. A future version of pip will drop support for Python 2.7.

查看错误日志缺少头文件

进入python-nss官网，写着To build python-nss you the C language header files and libraries for both NSPR and NSS will need to be installed. This is system and distribution specific, as such we cannot give you explicit instructions. On Linux typically these packages are called:

• nss-devel
• nspr-devel

yum install nss-devel -y

yum install nspr-devel -y

python setup.py install 安装的包 卸载方法

 

增加 –record 参数重新安装软件包，执行命令：

python ./setup.py install --record install.txt

 

删除安装文件，执行命令：

cat install.txt | xargs rm -rf
