Question

很简单，我在/ usr / local / bin /中有一个指向dart2js的链接，它会在运行时抛出重复的错误。

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，我看到了

...
/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链接，但我不知道为什么会知道。

我刚刚遇到这个问题并发布了此问题Can't run dart command line script using a symlink

我还添加了一个可能对您的情况有所帮助的解决方法 - 您可能需要对其进行一些调整，但它应该让您入门。

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

我查找bash脚本的当前目录并启动dart脚本   （Getting the source directory of a Bash script from within）。

#!/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]}

我没有使用io.Platform.script获取命令的（符号链接）名称，而是必须将其作为参数传递，以使其在dart脚本中可用（我使用用于启动脚本的符号链接的名称，如参数在飞镖脚本内）   这样我就必须区分脚本是否直接启动，否则使用io.Platform.script和args [0]。

我认为这应该更容易。

dart2js没有抛出这样的文件或目录错误
