好吧，我在虛擬環境中運行我的項目包。我通常通過PyCharm管理這些軟件包。 PyCharm告訴我我已經安裝了Pip 9.0.1。只有當我從命令行運行我的虛擬環境並打印pip版本時，它會顯示7.1.0。如果我嘗試使用升級我pip install --upgrade pip得到一個錯誤Pip版本virtualenv不匹配，不會升級

我的系統級PIP版本是9.0.1，雖然。我只是不知道發生了什麼。希望有人能夠闡明一些看法。我已嘗試重新安裝並重新安裝它，我嘗試使用安裝輪子，不起作用
Windows，順便說一下。
你的機器上可能有不同版本的Python ，比如Python 2和Python 3，每個都有自己的'pip'版本。當你使用'virtualenv'時，它會默認安裝python（你可以選擇的版本）和合適的點。然後在虛擬環境中，您可以根據需要升級'pip'。 – oliversm
@oliversm是的，這是問題，我不能升級它。錯誤日誌在問題中 –
