Try to reconnect to your TestRPC network in MetaMask:

<ol>
<li>Select <code>Main Ethereum Network</code> (or any other than Localhost 8545)</li>
<li>Select <code>Localhost 8545</code> again</li>

I've stumbled upon this issue after stopping and starting a new TestRPC node.

Using MetaMask <code>v3.14.1</code> you can reset your account as follow:
<blockquote>
Resetting an Account In the Settings menu, MetaMask has a &quot;Reset
Account&quot; button. This button wipes the current account's transaction
history, which is used to calculate the current account nonce.
<a href="https://i.stack.imgur.com/WJ4Ut.png" rel="noreferrer"><img src="https://i.stack.imgur.com/WJ4Ut.png" alt="enter image description here" /></a>
Normal users should never have a reason to use this feature.
This is useful for developers who reset a test network but want to
continue using the same account, forcing MetaMask to believe this
network ID is a clean network in a fresh state.

Old response:
Answer of yatskevich is correct.
However, for people how are using Truffle 4+ with &quot;truffle develop&quot;, you need to remove and reinstall MetaMask to get it work again, every time you run Truffle Develop!
This issue is addressed here:
<a href="https://github.com/trufflesuite/truffle/issues/681" rel="noreferrer">https://github.com/trufflesuite/truffle/issues/681</a>, here:
<a href="https://github.com/trufflesuite/ganache/issues/112" rel="noreferrer">https://github.com/trufflesuite/ganache/issues/112</a>, and also here: <a href="https://github.com/MetaMask/metamask-extension/issues/1999" rel="noreferrer">https://github.com/MetaMask/metamask-extension/issues/1999</a>
In short they are working on it and in the mean time you need to reinstall MetaMask every time!

Check your <code>truffle.js</code> or <code>truffle-config.js</code>

if you are using the <code>HDWalletProvider</code> like below, it seems that this is what causing the error

<pre><code>var HDWalletProvider = require("truffle-hdwallet-provider");
var mnemonic = "your mnemonic";

module.exports = {
 networks: {
 development: {
 provider: function() {
 return new HDWalletProvider(mnemonic, "http://127.0.0.1:8545/", 0, 50);
 },
 network_id: '*',
 gas: 9999999
 }
 },
 compilers: {
 solc: {
 version: "^0.4.25"
 }
 }
};
</code></pre>

remove the HDWalletProvider like below, it solves mine

<pre><code>module.exports = {
 networks: {
 development: {
 host: "127.0.0.1", // Localhost
 port: 8545, // Standard Ganache UI port
 network_id: "*", 
 gas: 4600000
 }
 },
 compilers: {
 solc: {
 version: "0.5.2"
 }
 }
};
</code></pre>

I have been experimenting with truffle recently and followed the following tutorial: <a href="http://truffleframework.com/tutorials/pet-shop" rel="noreferrer">http://truffleframework.com/tutorials/pet-shop</a>

Whenever I try to setup a transaction I keep getting the same error below

<blockquote>
 Error: Error: the tx doesn't have the correct nonce. account has nonce of: 14 tx has nonce of: 0
</blockquote>

Checked online and read up on a lot of articles related to this but so far haven't found what might be causing this issue.

<ul>
<li>Truffle v3.4.7</li>
<li>Solidity v0.4.13</li>
<li>Npm v5.3.0 </li>
<li>TestRPC v4.0.1 (also happen with Ganache)</li>
<li>Metamask v3.9.5</li>
</ul>

From what I understand it seems it is unable to find the previous transactions to hash the new transaction?

TestRPC/Ganache: the tx doesn't have the correct nonce

我最近一直在尝试松露，并遵循了以下教程：每当我尝试设置一个事务时，我总是得到下面相同的错误错误:错误: tx没有正确的nonce。帐户的随机数为: 14 tx的随机数为:0已在网上查看并阅读了许多与此相关的文章，但到目前为止还没有找到可能导致此问题的原因。松露v3.4.7Solidity v0.4.13Npm v5.3...
