A few tips in order

按顺序的一些提示

• restart the terminal
• restart the machine
• reinstall nodejs + then run npm install typescript -g

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

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

如果它仍然不起作用npm config get prefix，请运行以查看 npm install -g 放置文件的位置（附加bin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 your TSC command is not found in MacOS after proper installation of TypeScript (using the following command: $ sudo npm install -g typescript, then ensure Node /binpath is added to the PATHvariable in .bash_profile.

如果打字稿的正确安装（使用下面的命令后的MacOS没有找到您的TSC命令：$ sudo npm install -g typescript，然后确保节点/bin路径添加到PATH变量.bash_profile。

Open .bash_profileusing terminal: $ open ~/.bash_profile;

.bash_profile使用终端打开： $ open ~/.bash_profile;

Edit/Verify bash profile to include the following line (using your favorite text editor):

编辑/验证 bash 配置文件以包含以下行（使用您喜欢的文本编辑器）：

export PATH="$PATH:"/usr/local/lib/node_modules/node/bin"";

Load the latest bash profile using terminal: source ~/.bash_profile;

使用终端加载最新的bash配置文件：source ~/.bash_profile;

Lastly, try the command: $ tsc --version.

最后，尝试命令：$ tsc --version.

Easy fix for Mac I found. Just run these commands:

我发现 Mac 的简单修复。只需运行这些命令：

sudo npm install -g concurrently
sudo npm install -g lite-server
sudo npm install -g typescript

Nothing worked except this for me.

除了这个对我来说没有任何效果。

you are all messing with the global installations and -path files. Just a little error might damage every project you have ever written, and you will spend the rest of the nite trying to get a console.log('hi') to work again:-=.

你们都在搞乱全局安装和 -path 文件。一个小错误可能会损坏您曾经编写的每个项目，并且您将花费整晚的时间来尝试让 console.log('hi') 再次工作：-=。

If you have run npm i typescript --save-dev in your project - just try to run:

如果您在项目中运行了 npm i typescript --save-dev - 只需尝试运行：

npx tsc

npx tsc

and see if it works before messing with global stuff (unless ofc you really know what you are doing)

并在弄乱全局内容之前查看它是否有效（除非您真的知道自己在做什么）

干杯

This answer is specific for iTermV2 on MAC

此答案特定于 MAC 上的 iTermV2

1. First of all, I needed to instal as sudo(admin) during NPM install

   sudo npm install -g typescript

2. NPM installs the libraries under /usr/local/Cellar/node/<your latest version>/lib/node_modules/typescriptfolder and symlinks at /usr/local/Cellar/node/<your latest version>/bin/tsc

1. 首先，我需要sudo在 NPM 安装期间以（管理员）身份安装

   须藤 npm install -g 打字稿

2. NPM 在/usr/local/Cellar/node/<your latest version>/lib/node_modules/typescript文件夹和符号链接下安装库/usr/local/Cellar/node/<your latest version>/bin/tsc

hence I went ~/.zshrc ( .bashrc, if you use bash)and added /usr/local/Cellar/node/<your latest version>/binto the $PATH.

因此我去了~/.zshrc（.bashrc，如果你使用bash）并添加/usr/local/Cellar/node/<your latest version>/bin到$PATH。

1. reload the shell profile via source ~/.zshrc(.bashrc in your case)

3. 通过source ~/.zshrc（在您的情况下为 .bashrc ）重新加载 shell 配置文件

The only solution that work for me was put npx tsc -v or for the compiling npx tsc salida.ts

对我有用的唯一解决方案是放置 npx tsc -v 或用于编译 npx tsc salida.ts

"salida.ts" is the name of the file

“salida.ts”是文件名

Non-admin solution

非管理员解决方案

I do not have admin privileges since this machine was issued by my job.

我没有管理员权限，因为这台机器是我的工作发布的。

• get path of where node modules are being installed andcopy to clipboard
  • npm config get prefix | clip
  • don't have clip? just copy output from npm config get prefix
• add copied path to environment variables
  • my preferred method (Windows)
  • (Ctrl + R), paste rundll32 sysdm.cpl,EditEnvironmentVariables
  • under User Variables, double-click on Path> New> Paste copied path

• 获取安装节点模块的路径并复制到剪贴板
  • npm config get prefix | clip
  • 没有剪辑？只需复制输出npm config get prefix
• 将复制的路径添加到环境变量
  • 我的首选方法（Windows）
  • (Ctrl + R)，粘贴 rundll32 sysdm.cpl,EditEnvironmentVariables
  • 在用户变量下，双击路径>新建> 粘贴复制的路径
