Question

我在Mac OS El Capitan上，在Parallels中运行Windows 10 64位VM。我安装了Cygwin和Anaconda3。我想用pip安装两个包（pyrsistent和rpy2）。它们都抛出错误＆＃34;错误：[WinError 2]系统找不到指定的文件＆＃34;没有指定它无法找到的文件。

这是输出：

python3和pip都在路径中：

$ which pip
/cygdrive/c/Anaconda3/Scripts/pip

$ which python
/cygdrive/c/Anaconda3/python

尝试安装rpy2时，错误是相同的，因此它不是我试图安装的软件包的特定内容。有没有人有问题的想法或故障排除的想法？我已尝试调试install.py，但抛出错误的代码在C中。我已经尝试以详细模式进行安装，但它仍然没有说明它找不到的文件那种情况。（如果你想知道为什么我没有使用conda，那是因为它没有安装pyrsistent，而对于rpy2安装，它坚持将它链接到它自己的安装R，甚至在指定我自己的安装时，某些东西没有正确链接。我已经走了这条路，并且想坚持点。）

Answer 1

以下是阻止在Windows上安装python包的任何人的解决方法。有几个站点具有用于python包的Windows二进制文件。我能够为rpy2 here找到一个二进制文件，但是还有其他几个网站，如果你只是谷歌类似于＆＃34; python Windows二进制文件＆＃34;。然后我做了：

pip install rpy2-2.7.4-cp35-none-win_amd64.whl

pyrsistent不在该网站或我找到的其他几个二进制网站中。但我的开发团队中的其他人向我发送了他的Anaconda3 / Lib / site-packages目录中的/ pyrsistent目录，并在将其复制到我的机器上的同一目录后，我也能够导入pyrsistent。

它不漂亮，但它确实有用。
