pip install 返回无效语法

Question

I've just installed python 3.6 which comes with pip

However, in Windows command prompt, when I do: 'pip install bs4' it returns 'SyntaxError: invalid syntax' under the install word.

Typing 'python' returns the version, which means it is installed correctly. What could be the problem?

Answer 1

try this.

python -m  pip ...

-m module-name Searches sys.path for the named module and runs the corresponding .py file as a script.

Sometimes the OS can't find pip so python or py -m may solve the problem because it is python itself searching for pip .

Answer 2

You need to be in the specific folder where pip.exe exists, then do the following steps:

1. open cmd.exe
2. write the following command:

    cd "The path to the python folder"

or in my case, i wrote

    cd C:\Users\username\AppData\Local\Programs\Python\Python37-32\Scripts

3. then write the following command

    pip install *anypackage*

Answer 3

尝试以管理员身份运行 cmd（在右键单击后弹出的菜单中）和/或单独输入“pip”然后

Answer 4

Don't enter in the python shall, Install in the command directory.

Not inside the python pip cannot be installed inside the python.

Even in the version 3.+ you don't have to write the python 3 instead just python.

which looks like

python -m pip install --upgrade pip

and then install others

python -m pip install jupyter

Answer 5

"D:\\Program Files\\Py\\Scripts\\pip.exe" install numpy -U

YOUR PATH to pip.exe in Python folder + install + YOUR LIB + -U

Answer 6

The OS is not recognizing 'python' command. So try 'py'

Use 'py -m pip'

Answer 7

The problem is the OS can't find Pip. Pip helps you install packages MODIFIED SOME GREAT ANSWERS TO BE BETTER

Method 1 Go to path of python, then search for pip

1. open cmd.exe
2. write the following command:

Eg

cd C:\\Users\\Username\\AppData\\Local\\Programs\\Python\\Python37-32

In this directory, search pip with python -m pip then install package

Eg

python -m pip install ipywidgets

-m module-name Searches sys.path for the named module and runs the corresponding .py file as a script.

OR

GO TO scripts from CMD. This is where Pip stays :)

cd C:\\Users\\User name\\AppData\\Local\\Programs\\Python\\Python37-32\\Scripts>

Then

pip install anypackage

Answer 8

1. First go to python directory where it was installed on your windows machine by using

   cmd

2. Then go ahead as i did in the picture

Answer 9

Try:

pip3 install bs4

If you have python2 installed you typically have to make sure you are using the correct version of pip.

Answer 10

I use Enthought Canopy for my python, at first I used "pip install --upgrade pip", it showed a syntax error like yours, then I added a "!" in front of the pip, then it finally worked.

Answer 11

You can also go into the directory where you have your pip.exe or pip3.exe located. For me it was on my D drive so here is what I did:

D:\>cd python

D:\python>cd Scripts

D:\python\Scripts>pip3.exe install tweepy

Hope it helps

Answer 12

Chances are you are in the Python interpreter. Happens sometimes if you give this (Python) command in cmd.exe just to check the version of Python and you so happen to forget to come out.

Try this command

exit()
pip install xyz

Answer 13

The resolution is pretty easy, altough it took me a while to figure it out.

Two ways to solve this:

1 - Short one

Open your CMD and write

pip install module 
or
python -m install module

2 - Longest one

Open your CMD and check your Python version:

python

After you confirm you are in the correct version, still in the prompt write:

exit()

After that write:

pip install module 
or
python -m install module

That will do the work.

Answer 14

I found that you can download and install pip directly by running:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

Then you can run

python3 get-pip.py

And check the version using:

pip3 --version

I was then able to install Django

pip install Django

Answer 15

I had this error too! I found the problem: it had error cause i opened cmd then entered python then pip!! you shouldn't enter python! just open cmd then write "pip install bs4"

Answer 16

In windows, you have to run pip install command from( python path)/ scripts path in cmd prompt

C:/python27/scripts

pip install pandas

Answer 17

You need to run pip install in the command prompt, outside from a python interpreter ! Try to exit python and re try :)
