I have installed python3.6.4 and pipenv,and I have git my project to the centos7, and I want to install the project dependencies and used the code like that
pipenv install --deploy --ignore-pipfile

? ???????????????????????????????? 1/2 ? 00

ok, when I have tried so many methods, I found the solutions to the problem.
Use the code like this
pipenv install -r requirements.txt --python 3.6
and then use the commend like that
pipenv shell
pipenv run
at last, try again
pipenv install --deploy --ignore-pipfile
and it worded!

Pipenv can't install Twisted on Python 3.8

I originally ran into this issue using Pipenv to install the news-please package, but I've narrowed the issue down specifically to the combination of the Twisted package and Python 3.8. This pipfile:
[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true
[dev-packages]
[packages]
Twisted = "*"
[requires]
python_version = "3.8"
Results in this error:

When running pipenv install. Trying specific versions of Twisted doesn't seem to help. I can successfully install and use the package with pip3 or by installing from git, but would prefer to use the default pypi index because it simplifies my docker build.

pipenv install --dev

I have handled pipenv errors before and most were pretty reasonable (clashes between dependency and sub-dependecies), but this one makes less sense to me as I did not specifically installed this package, but rather pipenv added it to the pipfile.lock and it doesnt find that version all together while locally that version is available for some reason.
I dont know which dependency is asking for that specific version either.
Pipfile.lock section:
"pyparsing": {
"hashes": [
"sha256:530d8bf8cc93a34019d08142593cf4d78a05c890da8cf87ffa3120af53772238",
"sha256:f78e99616b6f1a4745c0580e170251ef1bbafc0d0513e270c4bd281bf29d2800"
],
"version": "==2.4.1"
},
Any ideas?
EDIT:
you can see in the releases for pyparsing that this version does exist. See it here

Turns out that pyparsing have deleted a version, which is really weird.
I ended up updating a package (scipy) and it update pyparsing to 2.4.1.1, now works fine

Unable to install Django with pipenv because of pytz package failure

This has caused problems for me when developing with django, the simplest case to reproduce this error follows.
I'm using Anaconda 4.6.4 running Python 3.6.5, pip version 19.0.3, and pipenv version 2018.11.26. I've updated all the packages, even tried to use previous versions of several packages.
When I use:
pipenv shell
I get a new virtual environment, then I try:
pipenv install django
I then get the following error message:

This occurs when I'm using command line, power shell, pycharm, atom editor. I've searched for similar errors online all over the place but can't find anything relevant to this. I tried looking at the pipenv source code for the batch_install and _clean_procs functions among others in the stack trace, but couldn't figure out why it's failing.

PermissionError: [WinError 5] Access is denied: 'C:\\Users\\#---No Crossing---#\\Documents\\Red-DiscordBot\\lib\\PIL\\_imaging.cp35-win_amd64.pyd'
I understand that this is some error with the permissions, but I'm not really sure what to do. Can someone help me? Thanks in advance!
[I don't really know too much about Command Prompt or folder permissions, so providing the commands would be nice :)] Thanks in advance once again

I found out the answer.
Here's what to do:
1. Open Command Prompt as Admin (Search for cmd in the start menu, right click and Run as administrator)
2. Type the following in: takeown /f C:\
3. If the operation was succesful, close Command Prompt and go to This PC.
4. Right click on the C:\ drive.
5. Click on Properties. 6. Click on the Security tab at the top of the window.
7. Go to your username and click Edit.
8. Tick the Full Control box.
9. Save it.
10. Run the command again. If this persists, the takeown command might not have executed correctly.
