在Ubuntu 18.04

Question

我正在尝试在Ubuntu 18.04上使用pip安装pydoop，并不断出现错误“ pydoop的构建轮子失败”。

pip install pydoop

/bin/sh: 1: hadoop: not found

似乎无法识别hadoop命令，但是，只要我在命令行中使用它，就没有问题。我在.bashrc文件中包含了hadoop的路径。

如评论中所建议，sh将不会使用.bashrc。尝试将Hadoop二进制文件添加到您的PATH中，例如export PATH="${hadoop_home}/bin:${hadoop_home}/sbin:${PATH}"
