Question

我一直在尝试在我的项目上设置laravel mix并按照laravel网站上的安装指南进行操作，但不断出现错误。

我的package.json文件是

create table a (
a_id integer,
a_name varchar2(10),
    PRIMARY KEY (a_id)

)

create table b(
b_id,
b_name varchar2(10),
a_id integer,
PRIMARY KEY (a_id),
FOREIGN KEY (a_id) REFERENCES a(a_id)
)

我运行任何npm run命令时得到的错误是

我正在一个流浪汉的盒子里运行我的项目，我正在运行laravel 5.4。

Answer 1

首先检查是否安装了cross-env模块。如果没有，请运行：

node_modules

之后，您需要转到cross-env文件夹。然后找到cross-env.js文件夹。进去找{4}。

就我而言，它是mode_modules/cross-env/dist/bin/cross-env.js

您需要在cross-env.js文件的scripts部分中更改package.json的路径。

{
  "private": true,
  "scripts": {
    "dev": "node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch": "node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "hot": "node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development webpack-dev-server --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
    "production": "node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
  },

........

}

Answer 2

执行命令

npm install

然后再试一次。

Answer 3

有几种方法可以解决此错误。

删除node_modules文件夹，然后再次执行npm install。如果它没有解决那么：
您可以通过解雇

dev dependency

npm install --save-dev cross-env

如果它当时没有解决：

全局安装cross-env npm install --g cross-env 它将安装在\ Users \ Roaming \ npm模块中。然后我建议你关闭你的外壳然后再打开它。解雇命令。

如果它没有解决的话： - 在Package.json中你可以使用：

node node_modules / dist / bin / cross-env cross-env ...

Answer 4

如果上述解决方案无效，请使用
刷新node_modules import java.util.Arrays; import java.util.Scanner; public class Matrix { public static void main(String[] args) { int[][] matrix = Matrix.matrixCreator(); for(int p = 0; p < matrix.length; p++) { for(int o = 0; o < matrix[p].length; o++) { System.out.println(Arrays.toString(matrix[p][o])); } } } public static int[][] matrixCreator() { int[][] matrix = new int[3][3]; Scanner scan = new Scanner(System.in); int[] convertToInt = new int[3]; for(int position = 1; position <= matrix.length; position++) { System.out.printf("Enter the elements of the matrix in row %d separating them with spaces: " , position); convertToInt[0] = scan.nextInt(); convertToInt[1] = scan.nextInt(); convertToInt[2] = scan.nextInt(); matrix[position - 1] = convertToInt; } return matrix; } }
这对我有用

Answer 5

您需要检查是否已安装cross-env模块。如果没有，请运行：

npm install cross-env

但你需要将它识别为“命令”。根据接受的答案提出修补路径（或者是吗？）使我更进一步，但仍然给了我一个错误。

我的解决方案是重新加载流浪汉“vagrant reload --provision”，并重置我的ssh / putty会话。

Answer 6

有时会删除/node_modules并运行

npm install

将解决此类问题。

Answer 7

如果您像我的情况那样急于解决此错误，只需从您的cross-env中删除package.json并运行没有它的laravel mix ..

Answer 8

快速的解决方案是运行：npm clean-install，可以修复laravel混合错误。

Answer 9

我不得不将存储库克隆到一个新文件夹中。无法识别哪个本地文件/设置导致了错误。

Laravel Mix＆＃34; sh：1：cross-env：not found error＆＃34;
