Scrapy 已安装，但无法从命令行运行 [英] Scrapy installed, but won't run from the command line

问题描述

我正在尝试在 ubuntu 机器上使用 scrapy 运行我在 python 中编写的抓取程序.已安装 Scrapy.我可以导入直到 python 没问题，当尝试 pip install scrapy 我得到 <块引用>

需求已经满足(使用--upgrade升级):scrapy in/system/linux/lib/python2.7/dist-packages

当我尝试从命令运行scrapy时，例如scrapy crawl ...，我得到了.

<块引用>

当前未安装程序scrapy".

这是怎么回事?符号链接是否搞砸了?以及如何解决它的任何想法?

解决方案

如果没有 sudo，pip 会安装到 $HOME/.local/bin、$HOME/.local/lib 等中.将以下行添加到您的 ~/.local/lib 中.bashrc 或 ~/.profile(或其他 shell 的适当位置):

export PATH="${PATH}:${HOME}/.local/bin"

然后打开一个新的终端或重新加载.bashrc，它应该会找到命令.

I'm trying to run a scraping program I wrote for in python using scrapy on an ubuntu machine. Scrapy is installed. I can import until python no problem and when try pip install scrapy I get

Requirement already satisfied (use --upgrade to upgrade): scrapy in /system/linux/lib/python2.7/dist-packages

When I try to run scrapy from the command, with scrapy crawl ... for example, I get.

The program 'scrapy' is currently not installed.

What's going on here? Are the symbolic links messed up? And any thoughts on how to fix it?

解决方案

Without sudo, pip installs into $HOME/.local/bin, $HOME/.local/lib, etc. Add the following line to your ~/.bashrc or ~/.profile (or the appropriate place for other shells):

export PATH="${PATH}:${HOME}/.local/bin"

then open a new terminal or reload .bashrc, and it should find the command.
