我正在进入Node.js代码库,这需要我通过NPM下载一些依赖项,即jQuery.

在尝试运行时npm install jquery,我不断收到此错误:

Your environment has been set up for using Node.js 0.8.21 (x64) and NPM

C:\Users\Matt Cashatt>npm install jquery

我正在使用"npm install"来下载和编译我编写的一个小node.js应用程序的所有依赖项.我使用的"package.json"文件是正确的,包含所有需要的信息.

其中一个要安装的软件包有"node-gyp"作为依赖项,所以我之前安装了"python2"软件包.

现在,在某个时刻我开始收到错误消息:

> node-gyp rebuild

我开始研究离子,我对此非常陌生,并且按照本教程,我知道已经问过这类问题,但没有适当的解决方案,请提供解决方案,第一步跟随,

1.已安装节点 - node-v8.9.0-x86
2.运行命令npm install -g cordova ionic

npm WARN deprecated node-uuid@1.4.8: Use uuid module instead

+ cordova@7.1.0
+ ionic@3.16.0

3. 然后运行命令ionic start myApp tabs ,得到以下错误

谢谢,

我正在尝试将Tesseract导入Angular2(TypeScript).我可以看到它保存到node_modules文件夹中,但在使用时

import { Tesseract } from '@types/tesseract.js';

它说:

[ts]模块'"c:/Users/black/Projects/projectCLI/tess/node_modules/@types/tesseract.js/index"'没有导出成员'Tesseract'.

在index.d.ts文件中有一个名为Tesseract的命名空间.

有没有其他方法来导入这个或我们是否以错误的方式看待这个？

我曾经npm install --save-dev @types/tesseract.js安装过打字稿Tesseract.

如果有任何使用tesseract的演示教程,请将它们链接到这里吗？

在此先感谢您的帮助.

试图安装Karma

npm install -g karma

产生警告

npm WARN optional dep failed, continuing fsevents@0.3.5

最后似乎没有安装Karma

karma init karma.config.js
'karma' is not recognized as an internal or external command (so a windows installation).

然而,似乎有一个业力

C:\Users\Me\AppData\Roaming\npm\node_modules\karma

和一个builerror.log文件
