Pip無法找到滿足要求的任何下載Flask == 0.10.1

Question

這完全是奇怪的，因爲這在我的機器上以前工作。我分叉回購從GitHub，創造了一個新的virtualenv，並試圖

pip install -r requirements.txt 

我收到以下錯誤：

Downloading/unpacking Flask==0.10.1 (from -r requirements.txt (line 1)) 
    Could not find any downloads that satisfy the requirement Flask==0.10.1 (from -r requirements.txt (line 1)) 
Cleaning up... 
No distributions at all found for Flask==0.10.1 (from -r requirements.txt (line 1)) 
Storing debug log for failure in /home/michael/.pip/pip.log 

及以下存儲在我的調試日誌：

DistributionNotFound: No distributions at all found for Flask==0.10.1 (from -r requirements.txt (line 1)) 

我的requirements.txt文件看起來像

Flask==0.10.1 
Flask-SQLAlchemy==2.0 
Flask-WTF==0.11 
Jinja2==2.8 
MarkupSafe==0.23 
SQLAlchemy==1.0.10 
WTForms==2.1 
Werkzeug==0.11.3 
argparse==1.2.1 
coverage==3.7.1 
itsdangerous==0.24 
nose==1.3.4 
wsgiref==0.1.2     

有沒有人有任何想法是什麼問題？我以前能夠在同一臺機器上的不同virtualenv上安裝Flask，所以這特別令人沮喪。此外，我試過

pip install SQLAlchemy 

和這工作正常。

pip install Flask 

或

pip install Flask==0.10.1 

給我相同的錯誤消息如上。

任何想法？

謝謝！

請檢查您是否可以訪問「https://pypi.python.org/simple/Flask/」。也許你需要爲https設置代理。
