25 #然后尝试一下运行 `conda -V` 命令行看是否已经安装成功,如果返回对应的版本信息,则说明安装成功。

 一、更新 conda 命令:conda update -n base conda
 二、安装 Scrapy 命令:conda install scrapy

2、遇到问题:tar (child): bzip2: Cannot exec: No such file or directory

tar (child): bzip2: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now

————————————

解决方法很简单,只要安装bzip2就行了,yum安装的命令如下:
yum -y install bzip2

如果:centos7安装scrapy error: command ‘gcc’ failed with exit status 1   执行以下命令:

1 yum install gcc libffi-devel python-devel openssl-devel

如果重装  Anaconda3 需要执行以下命令:

1 出现问题:ERROR: File or directory already exists: /root/anaconda3
2 
3 解决方案:删除即可 rm -rf   /root/anaconda3
