货物执行-拒绝[先前]铁锈安装许可-拒绝许可

Question

我用curl https://sh.rustup.rs -sSf | sh安装了生锈装置，并按照指示进行了安装。安装成功，路径被添加到.bash_profile中，如下所示：

export PATH=$HOME/.cargo/bin:$PATH

回送$PATH显示变量已正确设置，如下所示：

rust@rusty:~$ echo $PATH
/home/rust/.cargo/bin:/usr/local/bin:/usr/bin:/bin:/usr/games

我将/home作为一个单独的分区挂载，并通过/etc/fstab安装如下

# Mounting home partition
/dev/sda4                 /home                 ext4      rw,async,users      0 0

最初，我选择了noexec作为选项之一。但是，取消这一政策并没有给结果带来任何变化。

我怀疑我的默认/home分区权限，但没有任何其他的linux运行框来验证。

drwxr-xr-x 22 rust     rust     4096  Jan 19 19:45 rust

这个权限正确吗？

如果有人能弄清楚我遗漏了什么，注意/做错了什么，以及如何解决和解决这个问题，我们将不胜感激。

rust@rusty:~$ cargo
bash: /home/rust/.cargo/bin/cargo: Permission denied

它应该提示我使用cargo的帮助文档，但未能如愿以偿。

编辑-2添加了.cargo和.cargo/bin的权限

>> curl https://sh.rustup.rs -sSf | sh
info: downloading installer

Welcome to Rust!

This will download and install the official compiler for the Rust programming 
language, and its package manager, Cargo.

It will add the cargo, rustc, rustup and other commands to Cargo's bin 
directory, located at:

  /home/rusty/.cargo/bin

This path will then be added to your PATH environment variable by modifying the
profile files located at:

  /home/rusty/.profile
  /home/rusty/.bash_profile

You can uninstall at any time with rustup self uninstall and these changes will
be reverted.

Current installation options:

   default host triple: x86_64-unknown-linux-gnu
     default toolchain: stable
  modify PATH variable: yes

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

Rust is installed now. Great!

To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your PATH 
environment variable. Next time you log in this will be done automatically.

To configure your current shell run source $HOME/.cargo/env

问题是我所拥有的/etc/fstab条目。它在我改变了我的安装方式后起了作用。以下是我的新fstab条目：

/dev/sda4            /home/rusty            ext4            defaults            0  2

我将/home/rusty的所有者和组改为rusty，它起了作用。
