关于在centos上离线下载和安装python包的问题

请教：

我按照上述方法，当运行pip install --download ... 命令时，提示no such option，看上去是不能识别这个命令，求助，谢谢！

去掉--download即可

pip --help 仔细看看pip的指令集，里面说得很清楚

pip install [options] <archive url/path> ...

[nieoding]

新版pip已经不支持--download指令，
换成 pip download <yourpackage>

[冯斯特罗]

--download /tmp/offline_packages
这个不知道是干啥的.
一般 pip install -r requirements.txt
就可以.

谢谢！我已经按照最新的命令获取了安装包合集。 安装fastdtw==0.3.2时，出错了，提升如下。联网的情况下是可以安装成功的，我的需求是不联网安装，请大侠帮忙再看看。 Collecting fastdtw==0.3.2 (from -r requirements.txt (line 13)) Complete output from command python setup.py egg_info: Compiling fastdtw/_fastdtw.pyx because it depends on /home/alex/anaconda3/lib/python3.6/site-packages/Cython/Includes/libcpp/vector.pxd.

有人知道吗？

重新描述一下问题吧： 环境：虚拟机 系统：CentOS 7，Python 3.6（Anaconda） 1、运行“pip download -d PythonPackages -i https://pypi.doubanio.com/simple/ --trusted-host pypi.doubanio.com -r requirements.txt“ 获取了安装包，requirements.txt中含有fastdtw==0.3.2。 2、离线状态下，运行“pip install --no-index --find-links=PythonPackages -r requirements.txt”安装。 3、报错： Collecting fastdtw==0.3.2 (from -r requirements.txt (line 13)) Complete output from command python setup.py egg_info: Compiling fastdtw/_fastdtw.pyx because it depends on /home/alex/anaconda3/lib/python3.6/site-packages/Cython/Includes/libcpp/vector.pxd.
