ModuleNotFoundError: No module named ‘pip‘等python相关问题

python安装、使用过程中遇到的几个问题及解决。

ModuleNotFoundError: No module named ‘pip’

$ sudo pip install coloredlogs
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in 
    from pip import main
ModuleNotFoundError: No module named 'pip'

$ sudo pip remove coloredlogs
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in 
    from pip import main
ModuleNotFoundError: No module named 'pip'

$ pip -v
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in 
    from pip import main
ModuleNotFoundError: No module named 'pip'

解决：

$ sudo apt-get install python3-pip

如果仍没解决时可以试一下：

$ sudo apt install --fix-missing python3-pip

正常时：

$ pip -V
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)

The virtual environment was not created successfully

$ python -m venv venv
The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

    apt-get install python3-venv

You may need to use sudo with that command.  After installing the python3-venv
package, recreate your virtual environment.

Failing command: ['/home/biren/Downloads/mstarutils/venv/bin/python', '-Im', 'ensurepip', '--upgrade', '--default-pip']

解决：

$ sudo apt-get install python3-venv

ModuleNotFoundError: No module named ‘coloredlogs’

$ ./MstarUtil.py -v
Traceback (most recent call last):
  File "./MstarUtil.py", line 3, in 
    import coloredlogs 
ModuleNotFoundError: No module named 'coloredlogs'

解决：

$ sudo pip install coloredlogs

self.logger.info … SyntaxError: invalid syntax

$ ./MstarUtil.py -h
  File "./MstarUtil.py", line 160
    self.logger.info(f"{' Partition map ':-^29}")
                                               ^
SyntaxError: invalid syntax

解决：

安装python 3.0以上版本即可

$ sudo apt-get install python3.6

Command ‘pip’ not found

$ pip install coloredlogs

Command 'pip' not found, but can be installed with:
sudo apt install python-pip

解决：

$ sudo apt-get install python-pip
如果是python 3.0版本以上时用如下：
$ sudo apt-get install python3-pip

另外说明 ：

pip是python的包安装、管理命令工具
