我在Mac OS El Capitan上，在Parallels中運行Windows 10 64位虛擬機。我安裝了Cygwin和Anaconda3。我想用pip安裝兩個軟件包（pyrsistent和rpy2）。他們兩個都會拋出一個錯誤「error：[WinError 2]系統找不到指定的文件」而沒有指定找不到的文件。在Cygwin中的pip安裝無法找到文件錯誤
下面是輸出：
$ pip install pyrsistent

兩個python3和PIP是在路徑：嘗試安裝rpy2所以它不是給包我的東西特別是當
$ which pip
/cygdrive/c/Anaconda3/Scripts/pip
$ which python
/cygdrive/c/Anaconda3/python
的錯誤是相同的試圖安裝。有沒有人有解決問題的想法或想法？我已經嘗試調試到install.py，但引發錯誤的代碼是在C中。我嘗試在詳細模式下進行安裝，但它仍然沒有說明在這種情況下無法找到哪個文件。 （如果你想知道爲什麼我沒有使用conda，那是因爲它沒有安裝pyrsistent，並且對於rpy2安裝，它堅持將它鏈接到它自己安裝的R，甚至在指定我自己的安裝，有些東西沒有正確鏈接，我已經走下了這條路，並想堅持點）。
