linux更新安装pyperclip模块

安装官网的版本下载了相应的包 结果没有用

sudo apt-get install xsel 
sudo apt-get install xclip 
pip install gtk to install the gtk Python module. 
pip install PyQt4 to install the PyQt4 Python module

打开后 使用仍然报错显示

>>> pyperclip.copy('The text to be copied to the clipboard.')
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/local/lib/python3.5/dist-packages/pyperclip/__init__.py", line 612, in lazy_load_stub_copy
    return copy(text)
  File "/usr/local/lib/python3.5/dist-packages/pyperclip/__init__.py", line 297, in __call__
    raise PyperclipException(EXCEPT_MSG)
pyperclip.PyperclipException: 
    Pyperclip could not find a copy/paste mechanism for your system.
    For more information, please visit https://pyperclip.readthedocs.io/en/latest/introduction.html#not-implemented-error

现在更新安装包如下：

python -m pip install --upgrade --force pip 
pip install setuptools==33.1.1

测试：

import pyperclip
pyperclip.copy('The text to be copied to the clipboard.')
pyperclip.paste()
