Pip无法正确安装python模块

我已将python升级到3.7.3，并创建了指向新版本的符号链接。我正在尝试o导入模块-请求，但失败并给出错误。我怀疑我的链接不正确。

which python
/usr/bin/python

# ls -lrt /usr/bin/python
lrwxrwxrwx 1 root root 28 May 22 12:36 /usr/bin/python -> /usr/bin/Python-3.7.3/python

 which pip
 /usr/local/bin/pip

 which pip3
 /usr/local/bin/pip3

# python -m pip install --user requests
/usr/bin/python: No module named pip

# python -m pip3 install --user requests
/usr/bin/python: No module named pip3


# pip3 install requests
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

You are using pip version 19.0.3, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.


# python
Python 3.7.3 (default, May 22 2019, 12:25:12)
[GCC 7.2.1 20170915 (Red Hat 7.2.1-2)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import requests
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'requests'
>>>

我希望在Linux终端中使用该模块。在Windows-cmd上工作正常。如有任何建议。
