dart2js不会抛出此类文件或目录错误

Question

很简单，我在/ usr / local / bin /中有一个指向dart2js的链接，该链接在运行时会引发重复的错误。

我跑了

sudo ln -s /Users/macbook/Development/dart/dart-sdk/bin/dart2js /usr/local/bin/dart2js

从终端运行dart2js时，系统会提示我

...
/usr/local/bin/dart2js: line 9: 1=/Users/macbook/Development/dart/dart-sdk/bin/dart2js: No such file or directory
/usr/local/bin/dart2js: line 9: 1=/Users/macbook/Development/dart/dart-sdk/bin/dart2js: No such file or directory
/usr/local/bin/dart2js: line 9: 1=/Users/macbook/Development/dart/dart-sdk/bin/dart2js: No such file or directory
/usr/local/bin/dart2js: line 9: 1=/Users/macbook/Development/dart/dart-sdk/bin/dart2js: No such file or directory
/usr/local/bin/dart2js: line 9: 1=/Users/macbook/Development/dart/dart-sdk/bin/dart2js: No such file or directory
... etc

我想我只是错误地使用了链接，但是我不了解为什么。

我前一段时间遇到这个问题并发布了此问题无法使用符号链接运行dart命令行脚本

我还添加了一种变通办法，它也可能对您的情况有所帮助-您可能需要对其稍加调整，但它应该可以帮助您入门。

我现在使用的一种解决方法是在与testscript.dart相同的目录中创建一个名为'testscript'的bash脚本，并链接到该脚本

我查找bash脚本的当前目录并启动dart脚本（ 从中获取Bash脚本的源目录 ）。

#!/bin/bash
ME="$(basename "$(test -L "$0" && readlink "$0" || echo "$0")")"

SOURCE="${BASH_SOURCE[0]}"
while [ -h "$SOURCE" ]; do # resolve $SOURCE until the file is no longer a symlink
  DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
  SOURCE="$(readlink "$SOURCE")"
  [[ $SOURCE != /* ]] && SOURCE="$DIR/$SOURCE" # if $SOURCE was a relative symlink, we need to resolve it relative to the path where the symlink file was located
done
DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"

${DIR}/${ME}.dart ${BASH_SOURCE[0]}

而不是使用io.Platform.script获取命令的名称（符号链接），我必须将其作为参数传递给它，以便在dart脚本中使用它（我使用了用于启动脚本的符号链接的名称，就像dart中的参数一样。脚本）这种方式我必须区分脚本是否直接启动，并使用io.Platform.script和args [0]。

我认为这应该更容易。
