无法在Ubuntu上安装DFINITY Canister SDK

Question

我正在按照找到here的步骤安装DFINITY Canister SDK。

当我运行下面的命令时，没有创建目录dfx (在/bin下)，因此无法识别dfx命令：

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

Command 'dfx' not found, did you mean:

  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)

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

Answer 1

从install命令的输出看，dfx似乎安装在/home/adel/bin/dfx中。你能验证一下吗：

1. dfx确实存在？

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

如果没有，它看起来好像安装不起作用。

如果是，您可以直接运行它：

"$HOME/bin/dfx" --version

1. 检查您的路径是否包含"/home/adel/bin"

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

如果没有，您可以使用以下命令添加：

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

. "$HOME/.bashrc"

dfx --version

Answer 2

当我使用该命令时

dfx --version

它无法识别。

但是当我使用完整的路径时，它是有效的。

sudo /home/osboxes/bin/dfx --version

dfx 0.8.0

Answer 3

我也有同样的问题。由于某种原因，有一个~/bin目录，所以我首先删除它，然后按照前面的答案操作：

ubuntu@ip-172-31-81-158:~$ PATH=~/bin:$PATH
ubuntu@ip-172-31-81-158:~$ export PATH
ubuntu@ip-172-31-81-158:~$ sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"
