typescript compiler (tsc) command not working with tsconfig
提问by bnsaa
I installed typescript globally ( npm install typescript -g
)
我全局安装了 typescript ( npm install typescript -g
)
Then created a folder, ran npm --init
, then npm intall typescript --save-dev
- it installed [email protected]
然后创建一个文件夹,运行 npm --init
,然后npm intall typescript --save-dev
- 它安装了 [email protected]
In the folder , I create 'helloworld.ts`
在文件夹中,我创建了“helloworld.ts”
var msg = 'Hello World';
console.log (msg);
ran tsc command with file option - tsc helloworld.ts
and see it compiled to helloworld.js
.
使用文件选项运行 tsc 命令 -tsc helloworld.ts
并查看它编译为helloworld.js
.
Next, I want to use tsconfig.json, so I run tsc --init
- this doesn't work, says Unknown option 'init'
接下来,我想使用 tsconfig.json,所以我运行tsc --init
- 这不起作用,说Unknown option 'init'
i say alright, let me try adding tsconfig.json manually and add it in the folder root as below:
我说好的,让我尝试手动添加 tsconfig.json 并将其添加到文件夹根目录中,如下所示:
{
"compilerOptions": {
"target": "es5"
},
"files": [
"helloworld.ts"
]
}
and I run tsc
on command prompt, but it won't work and outputs me the syntax, example and options of how to use tsc Syntax: tsc [options] [file] ...
我tsc
在命令提示符下运行,但它不起作用并向我输出如何使用 tsc 的语法、示例和选项Syntax: tsc [options] [file] ...
whats wrong?
怎么了?
where tsc
gives below:
where tsc
给出如下:
C:\Program Files (x86)\Microsoft SDKs\TypeScript.0\tsc.exe
C:\Program Files (x86)\Microsoft SDKs\TypeScript.0\tsc.js
C:\Users\Kap\AppData\Roaming\npm\tsc
C:\Users\Kap\AppData\Roaming\npm\tsc.cmd

this is the problem:
这就是问题:
C:\Program Files (x86)\Microsoft SDKs\TypeScript.0\tsc.exe
C:\Program Files (x86)\Microsoft SDKs\TypeScript.0\tsc.js
uninstall-update-remove-get-rid-off: Visual Studio outdated extensions...
卸载更新删除删除:Visual Studio 过时的扩展...
or remove it from the path ...
或将其从路径中删除...
or rename the folder to confirm the problem ... then nuke it :)
或重命名文件夹以确认问题...然后取消它:)
check what happens if you do:
检查如果你这样做会发生什么:
md x
cd x
tsc --init
npm init -y
npm link typescript
echo console.log('it works') > index.ts
tsc -p .
node .
should output
应该输出
it works
also.
I'll need install typescript local to the project if
a module you depend on, depends on it
you need to use a compiler feature in "your" code
you need to use a different version than the installed globally
还。如果
您依赖的模块取决于它,我需要在项目本地安装打字稿,
您需要在“您的”代码中使用编译器功能,
您需要使用与全局安装的版本不同的版本
to init:
初始化:
tsc --init
to compile
编译
a 'project' (based on tsconfig.json):
一个“项目”(基于 tsconfig.json):
tsc -p .
where .means here
哪里。意思是这里
to compile 'other' project
编译“其他”项目
tsc -p other/tsconfig.json

What I did to adjust Typescript version of tsc command on my Windows system was:
我在 Windows 系统上调整 tsc 命令的 Typescript 版本所做的是:
Removing the Typescript 1.0 path here. (Start button-> Type : environment variables, click on the option (English version of Windows here) and choosing the system environment variable PATH).
在此处删除 Typescript 1.0 路径。(开始按钮->输入:环境变量,点击选项(这里是英文版Windows),选择系统环境变量PATH)。
Afterwards I entered:
后来我输入:
npm link typescript
npm 链接打字稿
And then I used the refreshenv command of Chocolateyto refresh the system PATH environment variable I adjusted.
然后我使用Chocolatey的refreshenv命令刷新我调整的系统PATH环境变量。
refreshenv
刷新环境
After then running the command: tsc -v I got: Version 2.2.1
然后运行命令:tsc -v 我得到:版本 2.2.1
The current version of Typescript is 3.5+, but I globally installed Typescript 2.2.1 because I am following a Typescript course using that version.
Typescript 的当前版本是 3.5+,但我全局安装了 Typescript 2.2.1,因为我正在学习使用该版本的 Typescript 课程。
