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
