在ubuntu系统下,系统默认python2.7和python3.5,但需要使用更高的python版本的pip3时可能遇到的错误
问题一:
Traceback (most recent call last):
File "/usr/bin/pip3", line 9, in <module>
from pip import main
ImportError: cannot import name 'main'
解决办法:
sudo vim /usr/bin/pip3
修改:
from pip import main
if __name__ == '__main__':
sys.exit(main())
为:
from pip import __main__
if __name__ == '__main__':
sys.exit(__main__._main())
注意:单下划线和双下划线
问题二:
使用pip3安装任何模块时的类似报错:
Traceback (most recent call last):

解决办法:
sudo vim /usr/bin/lsb_release
修改第一行,指明python的版本号,若安装的是python3.6则修改:
#!/usr/bin/python3
为:
#!/usr/bin/python3.6
