PythonAnywhere为2.7安装新模块

Question

I"m trying to install html2text using the command below:

>>pip install --username html2text

and I keep getting 'syntax error' and an arrow pointing to the last "l" in "install"...

Answer 1

This would happen when you run this command in the python console.

DEMO

$ python
>>> pip install
  File "<stdin>", line 1
    pip install
              ^
SyntaxError: invalid syntax
>>> pip install --username html2text
  File "<stdin>", line 1
    pip install --username html2text
              ^
SyntaxError: invalid syntax
>>> exit()
$ 

Exit from the python console, and run it outside the python shell at an OS command prompt

Here are a list of valid options: http://pip.readthedocs.org/en/latest/reference/pip_install.html#options May be you mean --upgrade ?

Answer 2

It needs to be run from Bash, not Python and the correct command you're looking for is:

pip install --user html2text

The --user is literal, and not a placeholder for your username.

Answer 3

Pip does not have a flag called --username . I have just checked with the manual for the Python package installer ( usr$ man pip ).

try:

sudo pip install html2text

Answer 4

use --user at last of your install command, so that the package will be installed only for the current user, not for all.

pip install html2text --user

or

pip3 install html2text --user
