Question

我正在尝试从Anaconda 2安装rp2软件包。

我手动将R exe文件的路径添加到Windows 8的环境变量中的Path字段，现在Path具有以下值：

    C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\Intel\TXE Components\TCS\;C:\Program Files\Intel\TXE Components\TCS\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Skype\Phone\;C:\Program Files\Microsoft SQL Server\Client SDK\ODBC\130\Tools\Binn\;C:\Program Files (x86)\Microsoft SQL Server\130\Tools\Binn\;C:\Program Files\Microsoft SQL Server\130\Tools\Binn\;C:\Program Files\Microsoft SQL Server\130\DTS\Binn\;C:\Program Files (x86)\Microsoft SQL Server\Client SDK\ODBC\130\Tools\Binn\;C:\Program Files (x86)\Microsoft SQL Server\130\DTS\Binn\;C:\Program Files (x86)\Microsoft SQL Server\130\Tools\Binn\ManagementStudio\;C:\users\alex\Anaconda2;C:\users\alex\Anaconda2\Scripts;C:\users\alex\Anaconda2\Library\bin;C:\Program Files\R\R-3.3.2\bin;

然后，我打开Windows Commander，移动到Anaconda 2的Script子目录并写道：

    pip install rpy2

Pip找到了rpy2并下载但是它给了我以下输出，导致出现错误信息：

   C:\Users\ALEX\Anaconda2\Scripts>pip install rpy2

您的建议将不胜感激。

Answer 1

您在分号后插入了一个空格：

...y\bin; C:\Program Files\R\R-3.3.2\bin;
         ^
         |

您在系统中插入的路径实际上是C:\Program Files\R\R-3.3.2\bin：无法正常工作。

删除空格即可。

（要检查一下，请输入where r以查看窗口是否找到它）

使用Anaconda 2安装rpy2会出现错误消息＆＃39;命令＆＃34; python setup.py.egg.info＆＃34;失败，错误1
