在过去的几个月里，我一直在研究使用python 3的程序。我已经测试了一段时间了，它似乎应该工作。所以我试图在DSM / Synology上运行它（模型：DS209 +，版本：DSM 4.2-3259）。可悲的是，我对这个环境一无所知。所以我从Synology Package Center安装了python3（3.3.2-0005）并让它运行起来。运行我的代码工作。唯一的问题是，我的程序使用“请求”库。但是我只是不能让pip运行。为了安装pip，我尝试在PuTTY中使用以下行。
curl -k https://bootstrap.pypa.io/get-pip.py | python3
我希望pip能够下载/安装并使用它来获取请求库。但后来发生了这种情况，我不知道自己做错了什么：

似乎使用sudo -H可以解决这个问题。但是我不知道该怎么做以及从哪里开始。谷歌搜索这个问题并没有多大帮助，因为我发现的事情要么让我理解太模糊，要么已经安装了pip这个问题。我希望这个问题也不是太模糊。
就像@hoefling已经提到的那样，这是一个特权问题。
通过SSH登录
ssh user@synology
并输入用户密码。
获得管理员权限
sudo su
并输入sudo密码。
获取安装文件
wget https://bootstrap.pypa.io/get-pip.py
并执行安装文件。
python get-pip.py
让我知道它是否适合你。
使用新的venv pip时可自动使用。例如：
user@host:~$ python3 -m venv env
user@host:~$ . env/bin/activate
(env) user@host:~$ pip --version
pip 7.1.2 from /volume1/homes/user/env/lib/python3.5/site-packages (python 3.5)
之后，您可以将pip升级到当前版本：
user@host:~$ pip install --upgrade pip
...
Successfully installed pip-18.0
这也有一个好处，即使用pip安装包不会破坏系统python。
要自动激活您的环境，您可以创建一个.profile：
user@host:~$ touch ~/.profile
user@host:~$ chmod u=rwx ~/.profile
然后使其内容看起来像这样：
#!/bin/sh
. env/bin/activate
Login to DSM with root permission via SSH/Telnet：
ssh [email protected]sudo -i切换到root。以root身份成功登录后，您将拥有安装pip所需的权限：
root@x:~# curl -k https://bootstrap.pypa.io/get-pip.py | python3
