python使用pip离线安装库（本机环境）_error: directory 'build/lite' is not installable.

踩

error: directory 'build/lite' is not installable. neither 'setup.py' nor 'py

很多问题都是pip版本太低造成的，所以在往下做之前，可以先升级一下pip为最新版本：

python -m pip install -U pip

二、联网下载库

1. 导出库信息

pip freeze > requirements.txt

这个命令是将已经通过pip安装的包的名称记录到requirements.txt文件中。

导出这个文件后，编辑文件，留下你需要的库，其他删除。

2. 下载库安装包

pip download D:\packages -r requirements.txt

注意：win10有可能因为写入权限的问题导致无法操作成功，可以直接进入目标文件夹然后执行：pip download -r requirements.txt

将requirements.txt中列出来的库下载到packages文件夹。

这里要注意，因为我的pip版本比较新，所以用的download，据说老一点的版本应该是install --download：

pip install --download D:\packages -r requirements.txt

注意：如果requirements.txt里面存在不能通过pip安装的库，下载过程会报错。

三、离线安装库

将requirements.txt和packages文件夹拷贝到需要离线安装的电脑，通过以下命令进行安装：

pip install --no-index --find-links=D:\packages -r requirements.txt

根据pip版本不同，里面的参数有可能是--find-link。

以下是我神奇的奇葩经历，python坑比较多，这还没用多久，就发现几个坑
