无法卸载并重新安装松露吗？

Question

请帮我卸载命令/安装松露。

[sudo] password for ubuntu:

ubuntu@ubuntu-vbox:~$ truffle v
Truffle v4.0.4 (core: 4.0.4)
Solidity v0.4.18 (solc-js)

ubuntu@ubuntu-vbox:~$ sudo npm install -g [email protected]
npm WARN deprecated [email protected]: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)
/home/ubuntu/.npm-global/bin/truffle -> /home/ubuntu/.npm-global/lib/node_modules/truffle/build/cli.bundled.js

added 82 packages in 9.783s

ubuntu@ubuntu-vbox:~$ truffle v
Truffle v4.0.4 (core: 4.0.4)

重新安装版本4.1.15后仍是松露v4.0.4版本

我过去曾经使用过。

您将需要：

which truffle

将返回：

/ usr / local / bin / truffle

rm -f /usr/local/bin/truffle

然后继续重新安装过程。我希望这有帮助。
