无法在 Ubuntu 上安装 DFINITY Canister SDK

Question

我正在按照此处找到的步骤进行安装DFINITY Canister SDK。
当我运行以下命令时，未创建目录dfx（在 下），因此无法识别该命令：/bindfx

adel@adel-VirtualBox:~$ sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"

Command 'dfx' not found, did you mean:

  command 'fx' from snap fx (11.1.0)
  command 'dfix' from snap dfix (0.3.5)
  command 'dx' from deb dx (1:4.4.4-12build2)
  command 'dex' from deb dex (0.8.0-2)
  command 'dfc' from deb dfc (3.1.1-1)
  command 'df' from deb coreutils (8.30-3ubuntu2)

See 'snap info <snapname>' for additional versions.

adel@adel-VirtualBox:~$ cd /bin
adel@adel-VirtualBox:/bin$ cd dfx
bash: cd: dfx: No such file or directory

下面是我的Ubuntu版本：

adel@adel-VirtualBox:~$ lsb_release -a

从安装命令的输出来看，dfx 似乎安装在/home/adel/bin/dfx. 您能否验证一下：

1. dfx确实存在吗？

test -e /home/adel/bin/dfx && echo yay found it || echo oh no

如果没有，看起来好像安装失败。

如果是的话，可以直接运行：

"$HOME/bin/dfx" --version

2. 检查您的路径是否包含“/home/adel/bin”

echo "$PATH" | tr : "\n" | grep "$HOME/bin"

如果没有，您可以添加它：

echo 'export PATH="$PATH:$HOME/bin"' >> "$HOME/.bashrc"

. "$HOME/.bashrc"

dfx --version
