node.js - antlr4-tool 在 Win10 中失败并显示 : Error: Command failed: which java

Question

在 Win10 中运行，为了在 Node.JS 中创建解析器，我安装了 ANTLR4 工具:

npm install --save-dev antlr4-tool

然:

c:/prj/parser/node_modules/.bin/antlr4-tool.cmd -o parser grammar/Lang.g4

但收到:

Compiling grammar/Lang.g4...
'which' is not recognized as an internal or external command,
operable program or batch file.
child_process.js:677
    throw err;
    ^

Error: Command failed: which java
'which' is not recognized as an internal or external command,
operable program or batch file.

我安装了 Java，运行时可以看到它的位置:

where java

但是因为我在 Windows 中，所以我不明白为什么命令是 which 而不是 where...

Answer 1

对于到达这里的任何人来说，这是一个错误，显然源于 Linux 和 Windows 之间的差异(Linux 中的 which 命令在 Windows 中是 where)。

要 W/A，仅当您在 Windows 中工作时，更改文件:

.../node_modules/antlr4-tool/dist/antlr-core/antlr-compiler.js，第 98 行，来自:

child.execSync('which java');

到:

child.execSync('where java');
