[英]pip fails to find any packages from requirements.txt
我有一個requirements.txt
文件,其中列出了以下軟件包:
appdirs==1.4.3
APScheduler==3.3.1
asn1crypto==0.22.0
bcrypt==3.1.3
boto3==1.4.4
botocore==1.5.72
當我執行pip install -q -U -r requirements.txt
; 我收到以下錯誤:
找不到滿足 appdirs==1.4.3 要求的版本(來自 -r requirements.txt(第 1 行))(來自版本:)
找不到 appdirs==1.4.3 的匹配發行版(來自 -r requirements.txt(第 1 行))
但是,以下工作:
$ pip install appdirs
Collecting appdirs
Downloading appdirs-1.4.3-py2.py3-none-any.whl
Installing collected packages: appdirs
Successfully installed appdirs-1.4.3
手動安裝 appdirs 后,我嘗試再次從需求運行:
$ pip install -q -U -r requirements.txt
Could not find a version that satisfies the requirement APScheduler==3.3.1 (from -r requirements.txt (line 2)) (from versions: )
No matching distribution found for APScheduler==3.3.1 (from -r requirements.txt (line 2))
我現在嘗試為下一個命令指定確切的版本:
$ pip install APScheduler==3.3.1

如果指定requirements
文件,pip 怎么找不到包? 為什么在沒有它的情況下它會繼續找到相同的包?
PS:一切都在名為.env
的virtualenv
.env
。
$ pip -V
pip 9.0.1 from $PWD/.env/lib/python2.7/site-packages (python 2.7)
$ python -V
Python 2.7.13
$ which python
$PWD/.env/bin/python
執行pip --verbose
命令給出:

其中https://pip.<domain>
是我們自定義托管的pypi-server 層。
您需要將 pypi 服務器上的fallback_url
設置為https
URL,因為pypi.python.org
現在只允許 https 請求。 有關更多信息,請參閱此鏈接(python 郵件列表) 。
