Linux: Curl installed but -bash: :curl: command not found
提问by Chase Westlye
Running Debian Stretch on an r710. Using the non-free/contrib build for driver support.
在 r710 上运行 Debian Stretch。使用非自由/贡献构建来支持驱动程序。
When I try to use packages that I've installed (curl, zpool, etc), I have to include the path to the package... Which is a pain when I don't always know where packages install to.
当我尝试使用我已经安装的包（curl、zpool 等）时，我必须包含包的路径......当我并不总是知道包安装到哪里时，这很痛苦。
Two questions:
两个问题：
- How do I remedy the path issue in the short term?
- How do I amend Debian so that when packages are installed, their paths update/install automatically?
- 如何在短期内解决路径问题？
- 如何修改 Debian，以便在安装软件包时，它们的路径会自动更新/安装？

Either you can try run curl from the output above for example /usr/bin/curl then try execute this:
您可以尝试从上面的输出中运行 curl 例如 /usr/bin/curl 然后尝试执行此：
/usr/bin/curl
For a temporary fix until you solve the real problem you can do:
对于临时修复，直到您解决真正的问题，您可以执行以下操作：
cd /usr/local/bin; ln -s $(which curl) curl
Or you can just set an alias:
或者你可以只设置一个别名：
echo "alias curl='$(which curl)'" >> ~/.bashrc; . ~/.bashrc
Troubleshoot your problem:
解决您的问题：
Check so PATH folder has the correct paths exported:
检查 PATH 文件夹是否导出了正确的路径：
printf "%s\n" $PATH
Modify current PATH
修改当前路径
Use the export command to add new paths and see if that works you can then update your ~/.bashrc or ~/.bash_profile, but first you can try in shell without adding it permanent to $PATH
使用导出命令添加新路径并查看是否有效，然后您可以更新您的 ~/.bashrc 或 ~/.bash_profile，但首先您可以尝试在 shell 中不将其永久添加到 $PATH
export PATH=$PATH:/missed/bin/folder
To format your PATH variable for easy viewing in future you can add below function to your .bashrc
要格式化您的 PATH 变量以便将来轻松查看，您可以将以下函数添加到 .bashrc
function path(){
old=$IFS
IFS=:
printf "%s\n" $PATH
IFS=$old
}
