一、ImportError: cannot import name DependencyWarning

(1)问题描述  
通过ssh远程登录服务器(Ubuntu 18.04)后，输入命令“pip install -r requirements.txt”报错“**ImportError: cannot import name DependencyWarning**”

(2)**解决办法**

sudo pip install -r requirements.txt

二、WARNING: The directory ‘/home/xxx/.cache/pip’ or its parent directory is not owned or is not writable by the current user.

(1)问题描述  
采用sudo方式导致的WARNING，根据反馈的提示“The cache has been disabled. Check the permissions and owner of that directory. If executing pip with sudo, you may want sudo’s -H flag.”，**将/.cache/pip赋予给root用户**。

> xxx指username  
> sudo是给与暂时的root权限，chown是改变文件的归属者；-r指递归(不仅把pip文件夹赋予给root, 其子文件夹以及文件也赋予给root)

(2)**解决办法**

sudo chown -R root /home/$USERNAME/.cache/pip/

> 将$USERNAME换成自己取的名字

三、ERROR: Could not find a version that satisfies the requirement futures==3.2.0

(1)问题描述  
在按照“requirements.txt”搭建环境的过程中产生的ERROR。

(2)**解决办法**(从stackflow获得)

curl https://bootstrap.pypa.io/get-pip.py | python

> ①Note that upgrading pip via pip install --upgrade pip will also not upgrade it correctly. It is a chicken-and-egg issue（CSDN上有些答案便是pip install --upgrade pip，没法解决问题）  
> ②Note: You may need to use **sudo python** above if not in a virtual environment.(如果不是在虚拟机中，**要使用sudo python！！！**)

四、ERROR: Could not find a version that satisfies the requirement pkg-resources==0.0.0

(1)问题描述  
在按照“requirements.txt”搭建环境的过程中产生的ERROR。

(2)**解决办法**(从stackflow获得)  
把requirements.txt中的"pkg-resources==0.0.0"删掉掉；
