如何使用打字稿做出一个shell执行节点的文件 [英] How to make a shell executable node file using TypeScript

问题描述

通常，在节点的文件，我只是把

Normally in node files I just put

#!/usr/bin/env node 

在顶部并使其可执行以创建可从一个bash终端中运行的文件。但是，如果我这样做，在一个打字稿文件，编译说：错误TS1001：意外＃字符，并拒绝进行编译。那么，如何可以与一个打字稿外壳可执行节点的文件？

at the top and make it executable to create a file that can be run from a bash terminal. However if I do that in a Typescript file, the compiler says "error TS1001: Unexpected character "#"" and refuses to compile it. So how can I make a shell executable node file with Typescript?

推荐答案

您是对报告的bug微软，他们是错的，收为 wontfix 的

You were right to report the bug to Microsoft, and they were wrong to close it as wontfix.

，直到它的是的固定的，这里有一个解决方法。以下内容粘贴到一个文本文件并将其保存为 shebangify ：

Until it is fixed, here's a workaround. Paste the following into a text file and save it as shebangify:

#!/usr/bin/env node
var fs = require('fs');
var path = process.argv[2];
var data = "#!/usr/bin/env node\n\n";
data += fs.readFileSync(path);
fs.writeFileSync(path, data);

（注意要保留这个答案简洁，code上面没有任何错误检查或其他改进，所以需要您自担风险使用或使用的此内容来代替。另外，看到的这太问题约prepending的文件更多的信息。）

(N.B. To keep this answer concise, the code above doesn't have any error-checking or other refinements, so use at your own risk or use this instead. Also, see this SO question for more info about prepending to files.)

通过使用终端导航到该文件的目录，并执行与制作该文件的可执行文件：

Make the file executable with by using a terminal to navigate to the file's directory and executing:

$ chmod +x shebangify

一旦你创建了一个打字稿程序（例如名为 myscript.ts ），您希望编译，变成一个shell脚本（如名为

Once you have created a Typescript program (e.g. called myscript.ts) that you wish to compile and turn into a shell script (e.g. called myscript), do so by executing a sequence along these lines in your terminal:

$ tsc --out myscript myscript.ts ; ./shebangify myscript ; chmod +x myscript
