编译打字稿时找不到“tsc 命令" [英] 'tsc command not found' in compiling typescript

问题描述

我想安装打字稿，所以我使用了以下命令:

I want to install typescript, so I used the following command:

npm install -g typescript 

并测试tsc --version，但它只显示'tsc command not found'.我已经按照 stackoverflow、github 和其他站点中的建议尝试了很多方法.但它不起作用.我怎么知道安装了 typescript 以及它在哪里.

and test tsc --version, but it just show 'tsc command not found'. I have tried many ways as suggested in stackoverflow, github and other sites. but it doesn't work. How could I know typescript is installed and where it is.

我的操作系统是 Unix，OS X El Capitan 10.11.6，节点版本为 4.4.3，npm 版本是 3.10.5

my OS is Unix, OS X El Capitan 10.11.6, node version is 4.4.3, npm version is 3.10.5

推荐答案

一些小技巧

• 重启终端
• 重启机器
• 重新安装 nodejs + 然后运行 ​​npm install typescript -g

如果仍然不起作用，请运行 npm config get prefix 以查看 npm install -g 放置文件的位置(将 bin 附加到输出)并确保它们在路径中(节点 js 设置执行此操作.也许您忘记勾选该选项).

If it still doesn't work run npm config get prefix to see where npm install -g is putting files (append bin to the output) and make sure that they are in the path (the node js setup does this. Maybe you forgot to tick that option).
